Abstract

Automatic loading and unloading of tape reels to and from tape drives is enhanced by enabling a single autoloader to travel along a row of tape drives, for servicing a plurality of drives rather than a single drive.

Autoloader for Tape Drives

Automatic loading and unloading of tape reels to and from tape drives is enhanced by enabling a single autoloader to travel along a row of tape drives, for servicing a plurality of drives rather than a single drive.

An autoloader for tape drives is shown by V. M. Andrews et al in the IBM Technical Disclosure Bulletin, "Autoloader for Tape Drives," Vol. 8, No. 8, January 1966, Pages 1035-1040. The operation of that autoloader can be enhanced by making it movable along a bank or row of tape drives 10. A rail extends along the top of the drives immediately over reel-receiving cavities 11. Carriage 12 moves along the rail in accordance with computer-generated instructions. When carriage 12 is positioned over a tape reel-receiving cavity as at 13, reel 14 already in the cavity and to be removed is first accessed by pivotable arm 15. The motion is as follows. Arm 15 first moves axially outward as indicated by the dotted lines. It then rotates downwardly to be aligned with the hub of reel 14. A motor, not shown, then axially moves arm 15 into engagement with reel 14 (such as at B). Arm 15 then returns to dotted-line position rotating upwardly, while arm 16 moves outwardly and downwardly for aligning reel 17 with the hub in reel-receiving cavity 11. As soon as arm 16 is aligned, arms 15 and 16 move inwardly depositing reel 17 in cavity 11. The motion is again repeated as arm 16 separates from reel 17.

Both arms 15 and 16 are then brought to a p...
