Detailed explanation-1: -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.
Detailed explanation-2: -Magnetic tapes can hold anywhere between 1 to 15 terabytes of data per tape in a compact format, making them great for long term storage such as the archival of system backups that includes large files.
Detailed explanation-3: -Large organisations who need to back up their systems daily tend to use magnetic tapes to store their data. Magnetic tapes can store up to one terabyte of uncompressed data-as much as can be stored on a hard disk. Magnetic tape uses ‘serial access’ to find a piece of data.
