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.
A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and long archival stability. A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access ...
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.
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 ...
Linear Tape-Open (LTO), also known as the LTO Ultrium format, [1] is a magnetic tape data storage technology used for backup, data archiving, and data transfer.It was originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats available at the time.
Digital Linear Tape (DLT; previously called CompacTape) is a magnetic-tape data storage technology developed by Digital Equipment Corporation (DEC) from 1984 onwards. In 1994, the technology was purchased by Quantum Corporation , who manufactured drives and licensed the technology and trademark.
