Disk package capable of loading a disk package containing multiple disks of different types and locking mechanism dependent on individual disk type

摘要

A plurality of trays (T) are set in a disk package (P) loaded into a disk device, and different types of disks are rested on the trays (T). A first lock mechanism (L1) for locking all of the disks is provided in the package (P) such that this lock mechanism can be manually operated to unlock. A second lock mechanism (L2) locks only the trays on which RAM disks are rested, thereby preventing the RAM disks from being taken out. The disk device comprises unlocking members for releasing the locks established by both locking mechanisms.
