The first 3480 tape drives were introduced in 1984. The IBM 3480 was the first tape drive to employ magnetoresistive (MR) heads and the first to use chromium dioxide tape. One way the format stands out from earlier formats is that the gap between blocks is too small for the drive to stop the tape within it, so the drive must have a write buffer.
Most (but not all) modern tape cartridges are 1 ⁄ 2 in (13 mm) format tape, first popularized by the IBM 3480 and DEC DLT formats. This is a small, rectangular and easily handled tape cartridge compared to the previously common 7-track and 9-track round tape reels.
Cassette tape, a two-spool tape cassette format for analog audio recording and playback and introduced in 1963 by Philips; DC-International, a format that was created by Grundig after Phillips had abandoned an earlier format that was being created alongside the Compact Cassette; 8-track tape, continuous loop tape system introduced in 1964
Early IBM tape drives, such as the IBM 727 and IBM 729, were mechanically sophisticated floor-standing drives that used vacuum columns to buffer long u-shaped loops of tape. Between servo control of powerful reel motors, a low-mass capstan drive, and the low-friction and controlled tension of the vacuum columns, fast start and stop of the tape ...
9-track tape is a format for magnetic-tape data storage, introduced with the IBM System/360 in 1964. The 1 ⁄ 2 inch (12.7 mm) wide magnetic tape media and reels have the same size as the earlier IBM 7-track format it replaced, but the new format has eight data tracks and one parity track for a total of nine
The company provided the S-100 bus CUTS Tape I/O interface board, which offers both CUTS and Kansas City standard support to any S-100 system. The Quick CUTS standard proposed by Bob Cottis and Mike Blandford and published in the Amateur Computer Club newsletter operated at 2400 baud, encoding "0" as a half-cycle of 1200 Hz and "1" as a whole ...
Currently, as of 2007, Graham Magnetics buys used tape cartridges and reconditions them for reuse. For the period 1995–1999, Graham was a part of Anacomp Corp. During this time, Anacomp/Graham was the world leader in open-reel computer tape production and one of 3 major manufacturers of IBM 3480 Family tape cartridges. They sold tape under ...
After a failed attempt to develop an IBM-compatible mainframe, and an optical disk product line, the company filed for Chapter 11 bankruptcy protection in 1984. Starting in 1987, new management invested in an automated tape library product line that "picked" tapes from a silo-like contraption with a robot arm. StorageTek emerged as a dominant ...
