Description

  The present invention relates to an optical disk device and an optical disk processing system, and more particularly to a verify process.

  Conventionally, a verify process for ensuring the reliability of recorded data is known. The verify process is a process for confirming whether or not the user data can be normally reproduced without error according to a strict error evaluation standard after the user data is recorded. In the case of a recordable optical disc, there are a lead-in area, a user data area, and a lead-out area. For data recorded in the lead-in area, can the tray be ejected after data recording, and the optical disc loaded again to start up normally? Confirm by no. Further, the reliability of the data recorded in the user data area is ensured by executing the above verify process. However, the lead-in area has a problem that it takes time due to a wasteful operation of ejecting / loading the tray, and there is a problem that a start-up process takes a long time even when the lead-in is illegally recorded. Further, for the user data area, since the verification process is accompanied by the reproduction of the recorded data, when the verification process is performed, the data recording and the data reproduction are repeatedly performed, so that the actual recording speed is lowered. There's a problem.

  Japanese Patent Application Laid-Open No. 2004-151561 discloses a technique for verifying only a predetermined area immediately before the normal recording end area or only a predetermined area immediately before the error occurrence area to shorten the processing time. Patent Document 2 discloses determining whether or not to perform a verify operation based on a matrix table indicating whether or not the verify operation exists in a one-to-one correspondence with each media ID previously owned in the optical disk drive. .

  However, any of the above prior arts automatically sets the presence / absence of verification or the verification area on the drive side, and there is a problem that the efficiency is low in a specific optical disc as well as flexibility. For example, when manufacturing custom-made optical discs used for school materials, souvenirs, gifts, etc., the same recorded data will be automatically recorded on multiple optical discs, especially to ensure the quality of the recorded data. The data part is roughly determined. In such a case, for example, it is not meaningful to verify only the outer peripheral portion where an error is likely to occur, and it is desirable to verify only the data portion for which it is desired to ensure the quality of the recording data. Of course, since the data portion for which the quality of data is to be ensured varies depending on the data content to be recorded, it is desirable that it can be set adaptively according to the data.

  An object of the present invention is to provide an apparatus and a system capable of adaptively and efficiently performing a verify process.

The present invention relates to an optical disc apparatus having a verify process for reproducing recorded data after recording on an optical disc and confirming whether or not the data can be normally reproduced, a recording means for performing user data recording, and verifying means for processing, in the recording area of the optical disc, have a control means for controlling said verifying means so as to verify processing the lead-in area, the control means, according to the execution mode set by the user The verifying means is controlled to immediately verify the area or to verify the area in a close command .

  The present invention also provides the above optical disc apparatus, a printing unit for printing on the label surface of the optical disc, display means for displaying a setting screen for the user to set an area to be verified, and setting by the user And an optical disk processing system for continuously processing data recording in the optical disk device and label surface printing in the printing unit.

  The present invention also provides a plurality of optical disc devices, display means for displaying a setting screen for a user to set a region to be verified, and information on the region set by the user to the optical disc device. And an optical disc processing system for continuously processing data recording in the plurality of optical disc apparatuses.

  According to the present invention, a verification process can be performed adaptively and efficiently.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a block diagram of the internal configuration of the optical disc apparatus 15. The optical disk D loaded by the disk tray is clamped by a magnet clamper (not shown), is placed on the turntable 100, and is rotated together with the turntable 100 by a spindle motor (SPM) 120. The spindle motor SPM 120 is driven by a driver 140, and the driver 140 is servo-controlled by the servo processor 300 so as to have a desired rotation speed.

  The optical pickup 160 includes a laser diode (LD) for irradiating the optical disk D with laser light and a photodetector (PD) that receives reflected light from the optical disk D and converts it into an electrical signal, and is disposed opposite to the optical disk D. . The optical pickup 160 is driven in the radial direction of the optical disc D by a sled motor 180, and the sled motor 180 is driven by a driver 200. The driver 200 is servo-controlled by the servo processor 300 in the same manner as the driver 140. In addition, the LD of the optical pickup 160 is driven by a driver 220, and the driving current of the driver 220 is controlled by an auto power control circuit (APC) 240 so that the laser power becomes a desired value. The APC 240 and the driver 220 control the light emission amount of the LD according to a command from the drive controller 320. Although the driver 220 is provided separately from the optical pickup 160 in the drawing, the driver 220 may be mounted on the optical pickup 160.

  When recording data on the optical disc D, data to be recorded supplied from the system side which is a host is supplied to the encode / decode circuit 360 via the interface I / F 400. The encode / decode circuit 360 stores data to be recorded in the buffer memory 380, encodes the data to be recorded, and supplies the data to the write strategy circuit 420 as modulated data. The write strategy circuit 420 converts the modulation data into a multi-pulse (pulse train) according to a predetermined recording strategy, and supplies it to the driver 220 as recording data. Since the recording strategy affects the recording quality, it is usually fixed to a certain optimum strategy. The laser light power-modulated by the recording data is irradiated from the LD of the optical pickup 160 and the data is recorded on the optical disc D. After recording the data, the optical pickup 160 reproduces the recorded data by irradiating the laser beam with the reproduction power, and supplies it to the RF circuit 260. The RF circuit 260 supplies the reproduction signal to the binarization circuit 340, and the binarized data is supplied to the encode / decode circuit 360. When executing the verify process, the encode / decode circuit 360 decodes the modulated data and checks whether or not an error is detected under conditions where the error evaluation criterion is stricter than usual. The result of the verification is supplied to the drive controller 320. The drive controller 320 determines whether to continue recording data according to the verification result, to perform replacement recording in a replacement recording area secured in advance, or to stop recording due to an error.

  In such a configuration, the optical disc apparatus according to the present embodiment does not always perform verification as in the prior art or automatically sets the area to be verified on the drive side, but manually sets the area to be verified by the user. . Specifically, it is configured so that a setting program of a host device such as a personal computer or a host device is started, a setting screen is displayed on the screen, and a user can freely set a verification area using this setting screen. . When the user sets using the setting screen, the set command is supplied from the host device to the drive controller 320 as an ATAPI command. The drive controller 320 receives a command from the host device, and executes a verify process according to the received command.

  FIG. 2 shows an example of the setting screen 50 displayed on the screen of the host device. The setting screen 50 includes a mode specifying unit 52 that specifies an execution mode and an area specifying unit 54 that specifies a verify area. The mode designating unit 52 has an immediate execution mode and an execution mode within a close (CLOSE) command, which can be selected alternatively. A check box 56 is displayed in front of each mode, and the user selects any mode by checking this check box. The area specifying unit 54 includes, as areas to be verified, lead-in (Lead-In), inner circumference (Inner), middle circumference (Middle), and outer circumference (Outer). Can be selected. A check box 56 is displayed in front of each area, and the user selects an area by checking this check box. Here, the inner circumference side, the middle circumference side, and the outer circumference side are not fixed areas with respect to the optical disc D, but are relative areas determined in the recording area of the recording data. That is, when the recording data is recorded up to the middle circumference of the optical disc D, the inner circumference side, the middle circumference side, and the outer circumference side are relatively set within the range of the recording area. Therefore, the outer peripheral side of the recording area may correspond to a physical middle peripheral area in the optical disc D. In the drawing, it is shown that the immediate execution mode is selected by the mode specifying unit 52, and the lead-in and the middle circumference side are selected by the region specifying unit 54.

  The area specifying unit 54 specifies an area to be verified, but other area designation methods are possible in addition to the inner circumference side, the middle circumference side, and the outer circumference side. For example, the inner peripheral side can be further divided into two, the middle peripheral side can be further divided into two, and the like. It can also be divided into a start area, an intermediate area, an end area, and the like. Furthermore, the area may be specified by directly specifying an address. If the address is specified directly, the start address and length may be specified.

  FIG. 3 shows an example of another setting screen 50. This is a setting screen 50 when the optical disc D is a multi-session disc. The setting screen 50 includes a mode specifying unit 52 and an area specifying unit 54. The mode designation unit 52 has an immediate execution mode and an execution mode within a close command, and the area designation unit 54 has a lead-in and a session lead-in (out). The session lead-in (out) includes an area for recording management information of each session, and this management information is called RMD (Recording Management Data) in a DVD-R or the like. In DVD + R etc., it is called SDCB (Session Disc Control Blocks). Either one or a plurality of lead-in and session lead-in (out) can be arbitrarily selected. A DVD + R or the like is multi-session, but a DVD-R or the like is multi-border. In this case, borderin (out) corresponds to session lead-in (out).

  When the verification mode and area are set using the setting screen 50 of FIG. 2 or FIG. 3, these setting commands are supplied to the drive controller 320, and the drive controller 320 executes a verify process in accordance with these setting commands. In the present embodiment, these setting commands are hereinafter referred to as “Easy Verify” setting commands.

  4 to 6 show processing flowcharts of the present embodiment. FIG. 4 shows main processing. First, idle processing and other initial setting processing are executed (S101), and it is determined whether or not an easy verify setting command is received (S102). When the easy verify setting command is received, processing is executed in accordance with the setting command (S103). Then, it is determined whether or not a close command has been received (S104), and when a close command is received, processing corresponding to this is executed (S105).

  FIG. 5 shows a detailed flowchart of processing according to the easy verify setting command in S103 of FIG. First, a setting command is received, and an execution mode and a verification area are set (S201). The verification area is divided into a lead-in area, an inner circumference side (Inner), a middle circumference side (Middle), and an outer circumference side (Outer). Execution) is set. For example, in the example of FIG. 2, the verify execution is set on the lead-in and the middle periphery side, and the verify non-execution is set at other times.

  Next, the addresses on the inner circumference side, the middle circumference side, and the outer circumference side are calculated (S202). As described above, the inner circumference side, the middle circumference side, and the outer circumference side are relatively determined according to the recording area. Therefore, according to the recording data capacity, the first 1/3 is set as the inner circumference side, 2/3 is set as the middle circumference side, and up to 3/3 is set as the outer circumference side, and the first number in each area is set. The track is subject to verification. Since the area of the lead-in address is determined for each type of optical disc D, the drive controller 320 automatically sets the address according to the type of optical disc D.

  Next, it is determined whether or not the mode is the immediate execution mode (S203). If the mode is the immediate execution mode, the verification is immediately executed on the data already recorded at the timing when the setting command is received (S204 to S210). . That is, if the verify of the lead-in is set, the verify of the lead-in is executed (S204, S205), and if the verify on the inner periphery is set, the verify of the data at the inner peripheral address calculated in S202 is performed. Execute (S206, S207). Thereafter, the verification on the middle and outer peripheral sides is similarly executed (S208 to S211). In the example of FIG. 2, only lead-in and middle-side verification are executed in S205 and S209.

  It should be noted that the readability (reproduction capability) at the time of verification is desirably set in consideration of compatibility with other drives. The readability at the time of verification is determined as an error when a PI (inner code parity) PO (outer code parity) or C1C2 error is monitored during verification reproduction and a predetermined threshold value (error evaluation standard) is exceeded. Adjust it.

  FIG. 6 shows a detailed flowchart of the closing process in S105 of FIG. First, it is determined whether or not the execution mode is a close command execution mode (S301). When the execution code is in the immediate execution mode, verification is not executed in the close process. In the execution mode within the close command, the verification of the specific area is executed in the close process that is always performed when the optical disc D is created (S302 to S309). Specifically, the normal close process is performed, and then the verification of the set area is executed.

  7 to 8 show processing flowcharts in the case of a multi-session disc. FIG. 7 is a detailed flowchart in S103 of FIG. In S502, it is determined whether or not the immediate execution mode is set, and verification of a specific area is executed in S503 to S508. In step S507, the user area is divided into a plurality of areas, and one or a plurality of these areas are verified. Of course, this is a case where one or a plurality of user data can be selected on the setting screen 50 of FIG. FIG. 8 is a detailed flowchart of the close process in S105 of FIG. In S601, it is determined whether or not the execution mode is the close command execution mode. In S602 to S607, the specific area is verified in the close process. That is, first, a normal close process is executed, and then the verification of the set area is executed. Note that the normal close process is a process for ending each session (border), and specifically, a process for recording border-in, border-out, and the like.

  Thus, in this embodiment, since the user can specify the area to be verified, the verification can be executed flexibly and efficiently. For example, when it is necessary to record certain data on a plurality of optical disks D such as a duplicator, an area in which particularly important data is recorded is specified. Therefore, the user can efficiently ensure the reliability of data in the plurality of optical discs D by setting the verification area such as the lead-in, the middle circumference side, and the like. In this embodiment, since the user can set not only the area to be verified but also the verification execution mode, the operability for the user is extremely high. When the immediate execution mode is set, it is possible to immediately verify already recorded data and ensure its reliability. In addition, when the execution mode within the close command is set, the verification is automatically executed only in the area selected by the user only by issuing a normal close command without newly issuing a special command. Therefore, it is easy to use. The fact that there is no need to issue a separate command for verification will also reduce the application program design load. Furthermore, even when verifying the lead-in, the verify time can be shortened because the tray is not ejected and reloaded as in the prior art.

  FIG. 9 shows an external view of an optical disc processing system including the optical disc apparatus according to the present embodiment.

First, when the optical disc D in the uppermost layer of the case C2 is clamped by the disc clamp unit 1 and sequentially conveyed to the printing unit 14 and the recording unit 15 and the predetermined processing is completed, the processed optical disc D is a collection case. Housed in C1. When the optical disc D of the case C2 is sequentially processed and the optical disc D accommodated in the case C2 is exhausted, the case C2 is made a recovery case at this time according to the judgment of the control program. When the process is continued, the unprocessed optical disc D accommodated in the case C3 is subjected to a predetermined process and then accommodated in the case C2 serving as a collection case. Thereafter, the same processing is repeated.

  In the above description, the optical disk D is first printed on the label surface by the printing unit 14, and then the data is recorded by the recording unit 15. However, the optical disk D is taken out from each case and is first stored in the recording unit 15.
