Your computer uses the read/write heads in a disk drive to store
and retrieve data on a disk. To write to a disk, the computer
spins it in the drive to position the area on the disk where the
data is to be written under the read/write head. A diskette has
an exposed area where the read/write head can access it.
Because data is stored magnetically, you can retrieve it, record
over it, and erase it-just as you play, record, and erase music
on a cassette tape.
