Control Function
POWER ON/POWER OFF Switch Turns the power on and off.
POWER Indicator Light
Illuminated whenever the power is on.
ENABLE/DISABLE Switch
When the READY light is on and this
switch is in the ENABLE position, the
disc drive is on -line. If this switch is in
the DISABLE position, the disc drive is
in local.
START/STOP Switch When this switch is moved to the START
position, the disc pack begins rotating, a
set of brushes cleans any dust from the
disc surfaces, and then the head assembly
emerges and positions itself at the outer-
most track. When this switch is moved to
the STOP position, the head assembly re-
tracts into the wall of the disc drive and
the pack slows to a halt.
READY Indicator Light Provided that no FILE UNSAFE condition
exists, the READY light is on whenever
the disc pack is rotating at the proper
speed (2400 rpm + 2%).
FILE UNSAFE Indicator Light The FILE UNSAFE light turns on when-
ever the disc drive detects a malfunction
which could conceivably result in loss of
recorded data. When the FILE UNSAFE
light turns on, any read or write opera-
tion currently in progress is terminated
immediately, and the disc drive cannot
-respond to any further instructions. To
turn off the FILE UNSAFE light, the
operator must move the START/STOP
switch to the STOP position and then
(after the pack has slowed to a halt) move
the START/STOP switch back to the
ST ART position.
