There are a "reproduction-only" type, which reads information stored on a disk called "M" or the like, and a "writable type", which can write information on the disk. In the writable type, a write-once optical disk device (CD-R) that can be written only once, a magneto-optical disk device that can be written any number of times, and a phase change disk (PD, CD-RW) device And the like.

[0003] Conventional optical disk devices are described above.
A plurality of optical disk devices are required because the disk is dedicated to the disk. In order to solve such inconvenience, for example, a disk device in which different types of disks can be mounted on the same tray has been developed.

[0004] As a conventional disk device to which such different types of disks are mounted, for example, there is one in which a disk cartridge containing a CD-ROM and a PD disk can be mounted on the same tray. FIG. 11 shows C
FIG. 12 is a perspective view for explaining the configuration of a tray on which a D-ROM and a disk cartridge can be mounted. FIG.
FIG. 13 is a side view of the tray for explaining a state where the ROM is mounted, and FIG. 13 is a side view of the tray for explaining a state where the disk cartridge is mounted.

The tray 1 has a double structure comprising an inner tray 2 on which a CD-ROM is mounted and an outer tray 3 on which a disk cartridge is mounted. The inner tray 2 is moved up and down inside the outer tray 3. Mounted as possible. The inner tray 2 has a small-diameter disk mounting portion 2a on which a disk having a diameter of 8 cm is mounted, and a disk mounting portion 2b on which a disk having a diameter of 12 cm is mounted. In addition, inner tray 2
Is normally urged to an upper position for supporting the CD-ROM 9, but is mounted so as to move downward when the disk cartridge 10 is mounted.

A lifting mechanism 4 for raising and lowering the inner tray 2 includes a pressing rod 5 for pressing the inner tray 2 in the direction A, a coil spring 6 for urging the pressing rod 5, and cams formed on both side surfaces of the outer tray 3. It comprises a groove 7 and a pin 8 which protrudes from both sides of the inner tray 2 and fits into the cam groove 7.

Since the spring 8 is pressed in the direction A by the spring force of the coil spring 6, the pin 8 is fitted over the cam groove 7. Therefore, the inner tray 2 is held at the upper position where the CD-ROM 9 is mounted. When the disk cartridge 10 is placed on the inner tray 2, the pin 8 moves down the cam groove 7 by the load of the disk cartridge 10 and descends.
