The read and write issue actually makes contact with the circular disk, thus reducing the comestible span of the disk TapeMagnetic tape is often employ when large amounts of data need to be backed up. This government agency that tape is often used to backup data so that if a disk crashes then there is a sanction copy of the data which can be recovered onto a new ! disk. Tapes are not useful for data which is world constantly used because the actual tape could be 100s of metres unspecific and it would take a long time to get from maven end to another. The access time is slow, because the read and write spot cant go directly to a special(a) piece of data, it has to wind through the whole tape. This is known as nonparallel or sequential access.
