Double-sided and high-density diskettes have 80 tracks on each

side and double-sided, double-density diskettes have either 40

or 80 tracks on each side. Diskettes can have 8, 9, 15, or 18

sectors per track.

A hard disk consists of two or more platters stacked on top of

one another and thus has four or more sides. In addition, a hard

disk has many more tracks per side than a diskette, but the

number of tracks depends on the capacity of the hard disk. The

number of sectors depends on the type of hard disk.

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 to the position under the read/write head

where the data is to be written. 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.

per side, 18 sectors per track, and hold up to 1.44MB of
