BACKGROUND OF THE INVENTION
The present invention relates to a disk device that is mounted on a personal computer (hereinafter referred to as a personal computer) or the like and reproduces or records information on a disk.
[0002]
[Prior art]
With the diversification of large-capacity media such as optical disks, CDs (Compact Disk), CD-ROMs (CD read only memory), CD-Rs (CD recordable), CD-RWs (CD rewritables) etc. The drive which can handle various discs is installed. Recently, media such as DVD (Digital Versatile Disk), DVD-R (DVD recordable), and DVD-RAM (DVD random access memory) have been remarkably widespread, and personal computers equipped with drives that can handle these media have appeared. Yes.
[0003]
However, the various types of discs described above have almost the same external shape and are difficult to distinguish at first glance. Therefore, the user often causes confusion and mishandles the handling. For example, the disc inserted into the drive for playing a CD may actually be a DVD, or the disc inserted into the drive for recording on a CD-RW may actually be a CD-R. In order to eliminate such mistakes, in the past, the disk was taken out and checked each time, or software installed on the PC (writing software, etc.) was started and the type of disk was checked on the monitor. I was trying to do it. For this reason, it takes time and effort to confirm the type of the disk.
[0004]
Therefore, as a means for easily confirming the type of the disk, for example, it is conceivable to provide a display indicating the disk type on the front surface of the drive. In Japanese Patent Laid-Open No. 10-228718, in order to discriminate between a CD and a DVD, an LED (light emitting diode) is provided corresponding to each disk, and when a CD or DVD is loaded, the LED corresponding to each is provided. An optical disc apparatus is described in which the type of the disc can be confirmed by turning on. According to this, it is possible to easily confirm whether the loaded disk is a CD or a DVD by lighting the LED without having to take out the disk and confirm the type of the disk on the monitor.
[0005]
[Problems to be solved by the invention]
However, in the above publication, there is no problem if the number of types of discs handled is small, but when handling many types of discs as described at the beginning, it is necessary to provide an indicator for each disc. There is a problem that the number of display devices increases and the cost increases, and a large display space is required.
[0006]
The present invention solves such problems, and it is an object of the present invention to provide a disk device that can reduce the number of display devices and save display space even if the number of types of disks increases. It is said.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a first display group that displays a disc type in a higher classification and a second display group that displays a disc type in a lower classification. The upper classification is a classification that represents a disc type by a large classification such as CD or DVD, for example, and the lower classification is a classification that represents a recording / reproduction mode such as ROM, R, or RW. The first display group is composed of a plurality of displays provided corresponding to disc types such as CD and DVD, and characters representing the disc type are displayed corresponding to the respective displays. . The second display group is composed of a plurality of displays provided corresponding to the recording / reproducing modes such as ROM, R, RW, etc., and characters representing the recording / reproducing mode corresponding to the respective displays. It is displayed. Based on the disc type thus discriminated, the indicator corresponding to the disc type of the disc is turned on in the first indicator group, and the display corresponding to the recording / reproducing mode of the disc is indicated in the second indicator group. The combination of a character indicating the disc type corresponding to the lighted display of the first display group and a character indicating the recording / reproducing mode corresponding to the lighted display of the second display group Display the disc type.
[0008]
In the present invention, when no disc is loaded, all the indicators of the first and second indicator groups are turned off, and when an illegal disc such as a disc not to be handled is loaded, You may make it light all the indicators of the 1st and 2nd indicator group.
[0009]
As described above, the characters indicating the disc type (upper classification) corresponding to the indicator lit in the first display group, and the recording / reproducing mode (lower classification) corresponding to the indicator lit in the second display group ) Is displayed in combination with the characters indicating), it is not necessary to provide as many display devices as the number of disc types, and the number of display devices and display space can be reduced.
