Disk driving unit

摘要

A compact disk drive unit capable of changing disks in a very short time. An access mechanism 10 for transferring a disk 5 between a rack 1 and a plurality of disk driving mechanisms 37a through 37f is pivotally supported by a central shaft which is approximately in parallel with the central shaft of the rack. A disk transfer means is provided to selectively face to the rack and the disk driving mechanisms to transfer a disk between them. Said disk driving mechanisms are radially disposed around the central shaft of the access mechanism to face to the revolving access mechanism at a preset distance. <IMAGE>
