Magnetic-tape data storage

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. Modern magnetic tape is most commonly packaged in cartridges and cassettes, such as the widely supported Linear Tape-Open (LTO)[1] and IBM 3592 series. The device that performs the writing or reading of data is called a tape drive. Autoloaders and tape libraries are often used to automate cartridge handling and exchange. Compatibility was important to enable transferring data.

Tape data storage[2] is now used more for system backup,[3] data archive and data exchange. The low cost of tape has kept it viable for long-term storage and archive.[4]
