The disk inside the casing a circular piece of magnetised plastic. Because it is floppy, it gets easily damaged. A floppy disk works instead similarly to a hard disk.

The read and write leave actually makes contact with the circular disk, thus reducing the commissariat span of the disk TapeMagnetic tape is often employ when large amounts of data need to be backed up. This government say-so that tape is often used to backup data so that if a disk crashes then there is a indorsement copy of the data which can be recovered onto a new disk. Ta! pes are not useful for data which is creation constantly used because the actual tape could be 100s of metres wide-cut and it would take a long time to get from one end to another. The access time is slow, because the read and write capitulum cant go directly to a special(a) piece of data, it has to wind through the whole tape. This is known as series or sequential access.
