MagstarA high-performance half-inch magnetic tape technology from IBM. Designated 3590 and enhancing the 3480 line, Magstar provides ESCON and SCSI connectivity to IBM mainframes and midrange systems. Tape libraries are available that hold from a handful to thousands of cartridges.
In 1984, the 3480 was a breakthrough magnetic tape technology, providing more storage in a 4x5x1" cartridge than in 10.5" reels, the common tape housing at that time. In addition, the drives took up half the floor space. In 1995, the new 3590 line was branded Magstar. See Magstar MP, half-inch tape and magnetic tape.
