A small read/write head in the computer’s disk drive interprets

the magnetic patterns. When you put a diskette in a drive, the

read/write head is directly over the large oval hole. The hole

allows read/write head access to the diskette so you can store,

retrieve, and delete data. The data is stored magnetically so

you can retrieve it, record over it, and erase it - just as you

play, record, and erase music on cassette tapes.

Choosing diskettes for the Apex

The Apex uses diskettes that are 5 l/4-inch, double-sided,

double-density, 48 TPI (tracks per inch). The diskette boxes

are usually marked DS-DD

or 2S-2D, soft sector, 48 TPI. Each

diskette can hold 360 KB of data, which is the equivalent of

about 150 pages of text. For best results, use only high-quality

diskettes with reinforced hub rings - the added reliability is

well worth the extra cost.

These diskettes are compatible with those used with the IBM

PC. This means you can use diskettes on the Apex that were

prepared and used on another IBM-compatible computer.

You need to format new diskettes before you can use them with

MS-DOS. The process of formatting erases all data on a diskette

and prepares it to receive new data, so be sure to format only
