Using Diskettes
Diskette drives allow you to store data on diskettes and retrieve and
use stored data. The Equity LT-286 has a 1.44MB 3 1/2-inch
diskette drive; it also supports an optional external 5 1/4-inch
diskette drive. This section explains how diskettes work and tells
you how to do the following:
l Choose diskettes
l Care for diskettes
l Make backup copies
l Write-protect diskettes.
How Diskettes Work
The diskettes you use are made of plastic coated with a magnetic
material and enclosed in a protective plastic case. Information is
recorded in magnetic patterns on both surfaces of the diskette.
Because data is stored magnetically, you can retrieve, record over,
and erase data, just as you play, record, and erase music on cassette
tapes.
When you insert a diskette in a drive, a metal shutter above the
access area moves aside, exposing the diskette surface. When your
computer reads data from or writes data to the diskette, it causes
the diskette to spin within its plastic casing. Then a small read/
write head positioned above and below the two diskette surface
locates the appropriate position on the diskette and carries out the
desired operation.
