ABSTRACT:
Disclosed herein is an automated library for data storage disks. Such library comprises at least one disk drive, means for storing a large number of disks, and disk transport means for transporting disks between the disk drive and disk-storing means. The disk-transporting means comprises a bi-directional disk picker assembly which operates to convey selected disks into and out of the disk-storing means and disk drive. A movably mounted drive unit functions to rotatably support the disk picker assembly for movement about an axis which is perpendicular to the direction in which disks are conveyed by such assembly, whereby "picked" disks can be flipped 180 degrees to present either side to the disk drive. The picker assembly handles each disk by means of a carrier, a generally rectangular frame which surrounds and releasably captures a disk. The picker mechanism is adapted to handle such carrier in any one of four different orientations. A single DC servo motor functions to selectively drive each of two disk conveyors in the picker assembly, as well as to selectively rotate the picker assembly.
