Any mounting scheme
in
which the disk drive
is
part of the structural integrity of the enclosure may cause equip-
ment operating problems and should be avoided.
Mounting schemes should allow for adjustable brackets or incorporate resilient members to accommodate
tolerances.
1.11.2
Dust Cover
The design of an enclosure should incorporate a means to prevent contamination from loose items- e.g., dust,
lint, paper chad - since the disk drive does not have a dust cover.
1.11.3
Cooling System Requirements
Heat dissipation
from
a single disk drive is normally 15 watts (51 Btu/Hr.) under high line conditions. When the
disk drive
is
mounted so that the components have access to
the
free flow of air, normal convection cooling allows
operation over the specified temperature range.
When the disk drive
is
mounted in a confined environment, air flow must be provided to maintain specified air tem-
peratures
in
the vicinity of the motors, the PCBA's, and the diskette.

DISKETTE
CARE, HANDLING, AND STORAGE
It
is
important
that the diskette be cared for, handled, and stored properly so that the integrity of the recorded data
is maintained. A damaged or contaminated diskette can impair or prevent recovery of data, and can result in dam-
age to the Read/Write heads of the disk drive.
The following list contains
information
on how the diskette can optimally be cared for, handled, and stored.
1.
Keep the diskette away from magnetic fields.
2.
Do not touch the precision surface of the diskette with fingers.
3.
Insert the diskette carefully
into
the disk drive until the backstop is encountered.
4.
Do not bend or fold the diskette.
5.
Put the diskette
into
its jacket when it is not
in
use.
6.
Store the diskette at temperatures between 10°c and 52°C or 50°F and 125°F.
1.13
WRITE PROTECT
The disk drive is equipped with a Write Protect Switch Assembly. This sensor operates in conjunction with a dis-
kette that has a slot cut in the protective jacket.
When the slot is covered with a self-adhesive tab, the diskette is write protected. The slot must be uncovered to
write on the diskette.
1.14
OPERATION OF THE DISK DRIVE
The disk drive consists of the mechanical and electrical components necessary to record and to read digital data
on a diskette. User-provided DC power at
+
12 V and
+
5 V is required for operation of the disk drive.
