On-line tape library system

Abstract From the Canadian patent

An on-line magnetic tape library system has a common transfer mechanism capable of advancement along a center aisle between rows of tape reels stored in one or more tape modules arranged in end-to-end relation. The transfer mechanism undergoes high-speed movement under the control of an operating program to different selected positions along the tape modules and includes a selector mechanism capable of selective removal of a tape from a storage position for transfer to and from an automated reel mount unit for a tape transport in such a way that several tapes may be processed at one time.
