Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape can with relative ease record and play back audio, visual, and binary computer data.
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track , later 9-track tape.
IBM 2401 System/360 tape drives that introduced the 9-track format Full-size reel of 9-track 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 ...
The magnetic flux distribution of a linear Halbach array may seem somewhat counter-intuitive to those familiar with simple magnets or solenoids. The reason for this flux distribution can be visualised using Mallinson's original diagram (note that it uses the negative y component, unlike the diagram in Mallinson's article). [ 4 ]
Elcaset, a format introduced in 1976 by Sony based on the RCA tape cartridge that was supposed to be more convenient than its predecessor; Digital based Digital Tape Format, a magnetic tape data storage format developed by Sony; Digital Audio Tape (DAT), a signal recording and playback medium developed by Sony and introduced in 1987
A magnetisation distribution is achieved along the magnetic tape. Finally, the distribution of the magnetisation can be read out, reproducing the original signal. The magnetic tape is typically made by embedding magnetic particles (approximately 0.5 micrometers [4] in size) in a plastic binder on polyester film tape. The most commonly-used of ...
