This government force that tape is often used to backup data so that if a disk crashes then there is a blurb cop y of the data which can be recovered onto a ! new disk. Tapes are not useful for data which is being constantly used because the actual tape could be 100s of metres abundant and it would take a long time to get from one end to another. The access time is slow, because the read and write mastermind cant go directly to a special(a) piece of data, it has to wind through the whole tape. This is known as accompanying or sequential access.
