Abstract

Tape library systems employing 1/2-inch tapes usually require a large area of floor space to accommodate storage of a large number of tape reels or volumes, plus attached or associated tape drives or transports. By volume sharing between the storage rack and tape transports, the width of a 1/2-inch tape library can be substantially reduced thereby facilitating differing configurations.

Single Spool Tape Library Arrangement

Tape library systems employing 1/2-inch tapes usually require a large area of floor space to accommodate storage of a large number of tape reels or volumes, plus attached or associated tape drives or transports. By volume sharing between the storage rack and tape transports, the width of a 1/2-inch tape library can be substantially reduced thereby facilitating differing configurations.

A typical 1/2-inch tape library will accommodate a plurality of tape drives, such as shown in the Burke et al Patent 2,941,738. In that patent, tape transports abut the storage racks. By placing the tape drives into the racks as at 10 and 12, the total width of the assemblage is substantially reduced. Performance is enhanced in that the travel distance from carriage travel path 13, usually extending between a pair of open-sided facing racks 14 and 15, is also reduced.

While the Burke et al patent teaches the use of a two-spool cassette in such a system, the well-known single-spool tape reels with wrap-around cartridges provide a more efficient storage. To load tape drive id, the carriage (not shown) traveling along path 13 selects a tape reel from one of the plurality of storage compartments. Than it moves to loading position 16 immediately in front of drive
10. The carriage then moves to unload position 17. An autoloader, not shown, constructed in accordance with the teachings of the Burke et al patent or any other form of autoloader, takes a tape reel from position 18 and loads it onto the ca...
