DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of recording information on a recording medium such as a read-only compact disk (hereinafter referred to as a CD-ROM), a floppy disk, a memory card or the like for recording information. The present invention relates to an apparatus and an information recording medium recorded based on the apparatus.

[0002]

2. Description of the Related Art Today, with the spread of personal computers, various data such as application programs and search databases are produced, and these data are generally recorded on information recording media such as CD-ROMs, floppy disks, and memory cards. It is provided by being recorded on a medium. These information recording media are recorded based on various standards of the respective information recording media, but the standards themselves do not incorporate copy protection measures, and unless any copy protection measures are taken, This is a situation that can be easily copied.

[0003]

In the case of CD-ROMs in particular, there has been no suitable recording medium capable of copying all data having such a large storage capacity, and the copying has not been performed much. With the advent of compact discs (hereinafter referred to as CD-Rs) capable of recording only, the situation surrounding compact discs (hereinafter referred to as CDs) has changed drastically, and an environment has emerged in which even large-capacity CDs can be easily copied. I have. Such copying is generally performed by using a personal computer. As a method, data of a CD-ROM is once copied to a hard disk having a dramatically increased capacity, and then copied to a CD-R. -If a ROM drive and a CD-R drive can be installed at the same time,
There is a method of copying to the like. However, if the data developed with a large development cost is easily copied in this way, the copyright cannot be protected. Therefore, the present invention has been made in order to improve such a drawback, and has taken measures to prevent copy to a recording medium such as a CD-R. It is an object of the present invention to provide an applied information recording method, an apparatus thereof, and an information recording medium on which the information is recorded.

[0004]

In the following description, the present invention will be described.
Related to the technology covered by the invention is the third information record.

This is a description of the information recording medium.
It is an explanation regarding the technology that forms the technical premise of the invention. In order to run a computer application program on a computer, it is necessary to install the application program recorded on a CD-ROM or the like into the computer, but the form of introduction is various. For example, there is a method in which a necessary program is first installed on a hard disk mounted on a computer and then executed. In this case, introducing information to the hard disk is called installation, and a procedure for introducing the information is described, and a program that executes the introduction in accordance with the described contents is called an installer. For example, in WINDOWS and MS-DOS (registered trademark of Microsoft Corporation), "SETU
P. EXE ”or“ INSTALL. A file having a name such as “EXE” is an installer. This file is first expanded in a memory of a computer and executed to obtain data relating to various contents of an application program (these data are referred to as main data in this specification). After preparing the installation environment, under this environment, the main body data, which is generally a compressed file stored on the CD-ROM as the installation source, is decompressed into the hard disk while being decompressed according to the installation procedure described in the installer. In other words, in this case, the installer is read first, and the main body data is read by executing the installer, or the application program may be directly executed without installation.

As described above, the execution of an application program provided on a CD-ROM means that there is a preceding program to be read first, and then a subsequent program is read under the execution environment of the preceding program. Take steps. Therefore, a part which cannot be read by an ordinary computer is provided in a part of the subsequent program, and an algorithm for executing the subsequent program while avoiding the uncopiable part in the preceding program executed prior to the subsequent program With this idea, the idea was that the normal operation of a genuine disk (original master) could be completely guaranteed, while the creation or execution of an illegally copied product could be prevented. Based on such an idea, the present invention has completed the invention in the following procedure.

In the present invention, when a computer application program is recorded on an information recording medium, a defective portion is provided in a subsequent program such as the above-mentioned main data which is a part of the program. Here, the defective portion means not only a literal defect such as a flaw, dirt, or alteration deviating from the physical characteristics defined by the standard of the information recording medium, but also a portion having a low read signal level in that portion, or a recorded physical format. Is a broad concept that also includes those whose logical format differs from the standard, or that the recorded file format is different from the predetermined type.
Any reading unit that operates in an operating environment of a computer where illegal copying is performed and cannot be read normally is included in the concept of the defective portion. In the present invention, after the preceding program is read in this way, a defective portion is included in a subsequent program that is subsequently read, but on the other hand, the preceding program, such as the installer or the execution program described above, is read ahead of the subsequent program. An algorithm for reading a subsequent program that does not include the defective portion is recorded in the preceding program that is read and executed. Alternatively, as another method, a method is proposed in which the location information of the defective portion and an algorithm for reading the subsequent program while avoiding the defective portion are recorded in the preceding program. As still another method, a method of switching to an operating environment in which the defective portion of the subsequent program can be read in the preceding program and recording an algorithm for reading the defective portion and verifying the content of the defective portion may also be recorded. suggest. FIG.
(A) schematically shows an application program on which such a recording is made. A subsequent program is provided with a defective portion, and the preceding program records an algorithm for avoiding reading of the defective portion. Represents.

[0007] As an effect of the above-mentioned measures, when the information recording medium is normally used, a preceding program such as an installer or an execution program is read and executed prior to the succeeding program, and under the control of the preceding program, the succeeding program is executed. Is read. At this time, there is a defective portion that cannot be read normally in the subsequent program, but an algorithm for avoiding this defective portion is described in a program that is read and executed earlier than the defective portion. Reading is performed while avoiding a defective portion. FIG. 1B is a flowchart showing a process for a defective portion when the application program of FIG. 1A is executed, and shows that the reading of the defective portion is avoided and the execution ends normally. I have.

On the other hand, such an algorithm does not work during illegal copying. For example, in a copy command such as a disk copy command attached to an OS that is usually used for illegal copying, the entire disk is copied under the assumption that the entire disk has the same data format. Try to copy. However, this defective portion is a reading unit that operates in the operating environment of the computer and cannot be read normally, so that the reading cannot be performed normally, and the computer stops the subsequent processing, thereby preventing illegal copying. . FIG.
FIG. 1C shows the application program of FIG.
FIG. 9 is a flowchart showing a response when a defective portion is encountered when a copy is made by a copy command, in which reading of the defective portion is not avoided and copying is impossible because reading is impossible.

Next, the operation of each of the above solutions will be described. The first information recording method includes:
At least a reading unit that operates in an operating environment of a computer in which illegal copying is performed records a subsequent program having a defective portion that cannot be read normally. On the other hand, a preceding program including information for specifying the location of a portion to be read of the subsequent program that does not include the defective portion and an algorithm for reading based on this information is recorded on the information recording medium.

Therefore, during normal use of the information recording medium recorded by this information recording method, the subsequent program is read under the control of the preceding program which is read and executed prior to the subsequent program. By the operation of the above-described algorithm, the subsequent program can be read normally even though there is a defective portion in the subsequent program that cannot be read normally.

On the other hand, if the information recording medium is illegally copied to another information recording medium by a copy command such as a disk copy command attached to the OS mounted on the computer, the copying is normally completed. do not do. In other words, since this copy command only copies the entire disk without analyzing the contents of the disk, it also attempts to copy a defective portion. However, this defective portion is copied under the normal operating environment of the computer where illegal copying is performed. The normal reading cannot be performed by the reading unit operating under the condition (1), and the computer stops the subsequent processing, thereby preventing illegal copying.

[0030] The second information recording method is as follows.
At least a reading unit that operates in an operating environment of a computer in which illegal copying is performed records a subsequent program having a defective portion that cannot be read normally. On the other hand, on the information recording medium, a preceding program including information for specifying a position where the defective portion of the subsequent program exists and an algorithm for avoiding reading of the defective portion is recorded.

Therefore, at the time of regular use of the information recording medium recorded by this information recording method, the subsequent program is read under the control of the preceding program, as in the first information recording method. Although there is a defective portion that cannot be read normally, the following program can be read normally by the operation of the above algorithm. In addition, by the same operation as the first information recording method, illegal copying from the information recording medium to another information recording medium can be prevented.

[0032] The third information recording method is as follows.
At least a reading unit that operates in an operating environment of a computer in which illegal copying is performed records a subsequent program having a defective portion that cannot be read normally. On the other hand, the information recording medium is switched to an operating environment in which the defective portion of the subsequent program can be read, and a preceding program including an algorithm for reading the defective portion and verifying the content of the defective portion is recorded.

Therefore, at the time of regular use of the information recording medium recorded by this information recording method, the subsequent program is read under the control of the preceding program as in the case of the first information recording method, and is read from the subsequent program. Although there is a defective portion that cannot be read normally, the following program can be read normally by the operation of the above algorithm. In addition, by the same operation as the first information recording method, illegal copying from the information recording medium to another information recording medium can be prevented.

Even if an illegally copied product of the information recording medium is created by any method, the illegally copied information recording medium does not have the defective portion, and the illegally copied information recording medium is not used. At the time of reading, since the preceding program cannot detect the defective portion which should originally exist, it is possible to verify that the information recording medium used for reading is not a genuine product, thereby preventing unauthorized use of illegal copying.

The fourth information recording method has the following operation in addition to the operation of any one of the first to third information recording methods. That is, in this information recording method, the information recording medium has a defective portion different from the recorded contents of the physical characteristics predetermined for recording on the information recording medium. Therefore, according to this method, since the defective portion has physical characteristics different from those of the normal portion, reproducibility of the defective portion can be ensured during reproduction of the information recording medium.

The fifth information recording method has the following operation in addition to the operation of any one of the first to third information recording methods. That is, in this information recording method, the information recording medium has a defective portion different from a logical recording format predetermined for recording on the information recording medium. Therefore, according to this method, the defective portion can be formed only by processing in a software area such as a file or a format, and there is no need to perform processing in a hardware area. Therefore, flexibility can be given to the method of forming the defective portion.

The first to fifth information recording devices have the same operations as the corresponding first to fifth information recording methods.

The first information recording medium is a reading unit that operates at least in an operating environment of a computer in which illegal copying is performed, and records and records a subsequent program having a defective portion that cannot be read normally. On the other hand, this information recording medium records a preceding program including information for specifying the location of a portion to be read of the subsequent program that does not include the defective portion, and an algorithm for reading based on this information.

Therefore, when this information recording medium is used regularly,
The subsequent program is read under the control of the preceding program which is read and executed prior to the subsequent program. However, due to the operation of the algorithm, there is a defective portion in the subsequent program that cannot be read normally. Nevertheless, the subsequent program can be read normally.

On the other hand, if the information recording medium is illegally copied to another information recording medium by a copy command such as a disk copy command attached to the OS mounted on the computer, the copying is normally completed. do not do. In other words, since this copy command only copies the entire disk without analyzing the contents of the disk, it also attempts to copy a defective portion. However, this defective portion is copied under the normal operating environment of the computer where illegal copying is performed. The normal reading cannot be performed by the reading unit operating under the condition (1), and the computer stops the subsequent processing, thereby preventing illegal copying.

The second information recording medium is a reading unit which operates at least in an operating environment of a computer in which illegal copying is performed, and records a subsequent program having a defective portion that cannot be read normally. On the other hand, this information recording medium
Information for specifying the location of the defective portion of the subsequent program and a preceding program including an algorithm for avoiding reading of the defective portion are recorded.

Therefore, at the time of regular use of this information recording medium,
The subsequent program is read under the control of the preceding program which is read and executed prior to the subsequent program. However, due to the operation of the algorithm, there is a defective portion in the subsequent program that cannot be read normally. Nevertheless, the subsequent program can be read normally. In addition, by the same operation as the first information recording medium, illegal copying from this information recording medium to another information recording medium can be prevented.

The third information recording medium is a reading section which operates at least in an operating environment of a computer in which illegal copying is performed, and records a subsequent program having a defective portion that cannot be read normally. On the other hand, this information recording medium
A preceding program including an algorithm for switching to an operating environment in which the defective portion of the subsequent program can be read, reading the defective portion, and verifying the content of the defective portion is recorded.

Therefore, when this information recording medium is used regularly,
The subsequent program is read under the control of the preceding program which is read and executed prior to the subsequent program. However, due to the operation of the algorithm, there is a defective portion in the subsequent program that cannot be read normally. Nevertheless, the subsequent program can be read normally. In addition, by the same operation as the first information recording medium, illegal copying from this information recording medium to another information recording medium can be prevented.

Even if an illegal copy of the information recording medium is created by any method, the illegally copied information recording medium does not have the defective portion, and the read of the illegally copied information recording medium is not performed. Sometimes, because the preceding program cannot detect the defective part that should originally exist,
It is possible to verify that the information recording medium used for reading is not a genuine product, and to prevent unauthorized use of an illegal copy.

The fourth information recording medium has the following operation in addition to the operation of the information recording medium described in any of the first to third information recording media. That is, the defective portion included in the information recording medium is different from the recorded content of the physical characteristics predetermined for recording on the information recording medium. Therefore, in this information recording medium, since the defective portion has physical characteristics different from those of the normal portion, reproducibility of the defective portion can be ensured during reproduction of the information recording medium.

The fifth information recording medium has the following operation in addition to the operation of the information recording medium described in any of the first to third information recording media. That is, the defective portion of the information recording medium is different from a logical recording format predetermined for recording on the information recording medium. Therefore, a defective portion of the information recording medium can be formed only by processing in a software area such as a file or a format, and there is no need to perform processing in a hardware area to form the defective section. Therefore, flexibility can be given to the method for forming the defective portion of the information recording medium.

The sixth information recording medium has the following operation in addition to the operation of the information recording medium described in any of the first to fifth information recording media. That is, this information recording medium has a recording of the subsequent program, but since this is another information recording medium for recording the preceding program, it can be dedicated to recording of the subsequent program, and is generally the subject of the application program. The recording capacity of the following program can be increased.

The CD-ROM according to the first embodiment, which is manufactured based on the CD-R recorded as described above, is normally installed at the time of normal use. Must be able to do it. Therefore, next, the possibility of copying the CD-ROM of the first embodiment and the possibility of installation at the time of regular use will be examined. The apparatus of FIG. 2 is used for this examination. The program used has the configuration shown in FIG. In FIG. 5, 6
Indicates a CD-ROM drive, 12 indicates an OS, 16 indicates an installer, 17 indicates main body data, 23 indicates a CD-ROM device driver, 25 indicates a CD-ROM, and arrows indicate directions in which read information flows. These programs use ordinary programs generally distributed in the market.

First, the possibility of copying a CD-ROM of the first embodiment will be examined. As a method of this copying, the information of the CD-ROM of the first embodiment is once copied to the HDD 2 of FIG. 2 and then copied to the CD-R. Generally, copying of a CD-ROM is performed by a disk copy command attached to an OS mounted on a computer connected to a CD-ROM drive. In the copying by the disc copy command, generally, the recorded contents of the information recording medium are not analyzed in the course of execution, and the entire disc is copied on the assumption that the entire disc has the same data format.

Therefore, after setting the CD-ROM of the first embodiment in the CD-ROM drive 6 of FIG.
, The central processing unit 1 mechanically reads the information of the CD-ROM of the first embodiment in units of sectors starting from the first sector and records the information in the HDD 2. The file A3, which is an abnormal file existing in the information content of the first embodiment, is also to be read.
Since it is configured not to be readable by an ordinary computer using hardware and software distributed in the market, the file A3 cannot be read by the program having the program configuration of FIG. Cancel the processing of. Therefore, from hard disk to CD-R
Cannot be copied, and unauthorized copying can be prevented. The method of copying is from CD-ROM to CD-ROM.
There is also a method of copying directly to the R,
The above is exactly the same as above except that the drive 7 is replaced.

First Embodiment In the case where the copying of a CD-ROM is performed noting the above-mentioned mechanical reading in units of sectors but focusing on the file, the copying of the information content of the first embodiment is performed at the time of copying. The contents of the root directory may be referred to. However, also in this case, as shown in FIG. 3D, the root directory contains a file A3 which is an abnormal file, and the file A3 is also a target to be read. However, similarly to the above, the file A3 cannot be read, and also in this case, illegal copy can be prevented.

Next, the possibility of installation of the CD-ROM of the first embodiment will be examined.

Is done. First, the installer is installed in the memory of the CPU 1, and then the main body data is installed according to the procedure of the installed installer. As described above, the installer reads the file shown in FIG.
As shown in (b), each file name of file A1, file A2, and file A4 except file A3, which is an abnormal file, is stored, and an algorithm for performing installation based on this file name is stored. Although the file A3 constituting the defective portion shown in FIG. 3B exists in the main body data, the installer reads only the remaining three files excluding the file A3.
Therefore, the CD-ROM of the first embodiment can be normally installed.

In the above description, the defective part is the CD-RO
A logical recording format different from the logical recording format predetermined for recording M (CD-R), that is, an abnormal file is specifically used, but a defective portion is recorded on CD-ROM (CD-R). There is also a method in which the recording contents are different from the recorded contents of the physical characteristics determined in advance. That is, information recording on the CD-ROM is actually performed by forming pits on the surface of the CD-ROM, and these pits are different from normal pits by some method. For example, the first embodiment CD

A hole is physically formed before or after formation of a pit on the surface of the CD-ROM on which the pits are arranged, or the pit is crushed after the pit is formed, thereby forming a defective sector.

In this case, the CD-ROM of the information content of the first embodiment is used.
The recording on the R is performed by using the file A3 as a normal file having dummy information, for example, all 0s, and using the normal CD-R device driver 13 shown in FIG. 4, and then manufacturing based on the CD-R. Sector No. of the CD-ROM written A hole is made in the board surface portion where a3 is arranged, or a pit in that portion is crushed. These processes can be performed simultaneously with the formation of pits in the CD-ROM mass production system process by processing the stamper. In the first embodiment, a circuit for forming defective pits in a recording amplifier of a CD-R drive, which is a circuit immediately before recording information on a CD-R, at a stage of recording information contents on the CD-R. And sector No. A method is also conceivable in which a defective pit is formed on a CD-R by operating the added circuit at the portion a3, and a CD-ROM is manufactured based on the CD-R.

Recording on a CD-R according to the above-described method does not require the use of a special CD-R device driver 13, and has the advantage that recording can be performed with a normal CD-R device driver 13. Further, according to the above-mentioned method, since the defective portion has different physical characteristics from the normal portion, it is possible to manufacture a CD-ROM with reproducibility of the defective portion when reproducing the CD-ROM.
