Abstract
A plurality of trays are arranged in a disk package disposed in a disk device, and disks of different types are placed on the trays, respectively. A first lock mechanism for locking all the trays is arranged in the package, and a locking operation of this lock mechanism can be released by a manual operation. A second lock mechanism is designed to be able to lock only a tray on which a RAM disk or the like is placed and to prevent the RAM disk or the like from being removed. However, when an projection portion of the tray is deformed, the tray can be removed.
