GENERAL DESCRIPTION
The SA850/851 diskette storage drives are enhanced double-headed versions of the standard Shugart
SA800/801 drives. SA850/851 drives provide up to four times the on-line storage capacity, faster access
time, and lower heat dissipation along with improved reliability and maintainability.
SA850/851 drives read and write
in
single or double density on standard diskettes and
on
both sides of two-
sided diskettes. The drives are exactly the same size as Shugart SA800/801 drives and are plug compatible.
The SA850/851 drives are also media compatible with IBM 3740 and S/32 single-sided drives as well as IBM
4964 and 3600 series two-sided units.
The proprietary
Fasflex™
actuator utilizes aflexible metal band for sure low friction head movement and a
fast 3ms track-to-track access time.
In
addition, Shugart's
Bi-Compliant™
read/write head assembly pro-
vides superior compliance resulting
in
excellent data integrity.
Other valuable features include: programmable door lock and write protect plus dual index sensor to dif-
ferentiate between single and two-sided diskettes.
The SA850/851 will prove highly cost-effective
in
applications such
as:
intelligent terminals, minicom-
puter/microcomputer systems, small business systems as well as word processing systems and intelligent
calculators.
