IBM 3480 magnetic tape subsystem
The IBM 3480 Magnetic Tape Subsystem of 1984 was a major milestone in IBM storage. Two radically new features incorporated into its design were shape and size: square cartridges replaced the traditional round tape reels and the overall footprint of the box was reduced. Seen here are design models of the 3480 control unit Model A22 (at left) with four Model B22 tape units.
