<p>PURPOSE:To obtain a disk cartridge suitable for miniaturization and thin formation, the disk drive device and the disk changer for using this disk cartridge. CONSTITUTION:The disk cartridge consists of an upper case 3, a lower case 2 and a middle case 4, and a disk 1 is housed in the middle case 4, and the middle case 4 is slid in a gap formed by sticking the upper case 3 and the lower case 2 to each other, and then the disk 1 is drawn out more than half to be used. Consequently, since the disk cartridge is prevented from dropping in, and an optical pickup part is allowed to approach the disk, a dead space inside the drive device is minimized, and an installation space for a circuit part is secured, and then the miniaturization and thin formation of the drive device are feasible.</p> |
