摘要

A storage disk module includes a frame (10), and a disk drive unit (20) having a storage disk. The disk drive unit is accommodated in the frame. A circuit unit (31) controls the disk drive unit, and is accommodated in the frame. A power source (30) supplies the disk drive unit and the circuit unit with energy. The power source is accommodated in the frame. The disk drive unit, the circuit unit and the power source are arranged side by side in the frame in a direction perpendicular to a direction in which the storage disk module is inserted into a locker. A back panel (40) is formed in a back portion of the frame. The back panel electrically connects the disk drive unit, the circuit unit and the power source to each other.
