IBM 7340

From Wikipedia, the free encyclopedia

TheIBM 7340"Hypertape" system was amagnetic tape data storageformat designed to work with theIBM 7074,7080and7090computers that was introduced in 1961 and withdrawn in 1971.

As a technology, it deviated in several ways from the then dominantIBM 7 tracksystem. It distinguished itself by having higher capacity, faster data transfer speed, faster load times, and lower wear on the tape. It achieved this by using tape that was twice as wide (1 vs. 1/2 inch), preloaded on two reels, and held in a large cassette.
