GENERAL

DESCRIPTION

SECTION I

INTRODUCTION

The

compact

SA810

single-sided

and

SA860

double-sided half-height 8-inch floppy disk drives offer a reliable, low

cost, high performance solution for OEM data storage applications which require maximum capacity in

the

smallest

space possible. The

SA810/860

drives are half the height of the Shugart SA801 floppy disk drive,

fit

in comfor-

tably with a CRT, require

ac voltage,

and

offer up to

1.6

megabytes of unformatted capacity.

The

SA810/860

offers the

follOWing

standard features:

a. Half-height sizing:

2.31

in. (59 mm) high by

8.55

in. (217 mm) wide by

12.00

in. (305 mm)

b. Interface

and

media compatibility with Shugart

SA801/851

disk drives

c. Low

heat

dissipation

d. Fast access time

ms track to
