b.
To cOITlplete the shutdown, press the VACUUM OFF and POWER
MAIN ON buttons. This action cOITlpletely reITloves vaCUUITl and
power froITl the tape drive.
Tape Mounting and Loading
1. To ITlount a tape reel, the following procedures should be followed:
a. Place the tape status switch in the TAPE CHANGE position.
b. Mount the tape reel and press it firITlly in place on the reel ITlount.
The stainless steel hub on the reel ITlount ITlust be pressed while
ITlounting the reel. After securing the reel on the reel ITlount,
release the hub and the reel will be locked in place.
c. Unwind approxiITlately three feet of tape froITl the supply reel and
thread it through the tape cleaners and under the read/write
head. Loop the free end of the tape up over the take-up reel in
a clockwise direction (ITlaking sure that the tape is not twisted).
Insert the forefinger of the left hand through one of the slots in
the take-up reel and ITlanually rotate the reel clockwise until at
least one cOITlplete turn of tape is firITlly seated on the reel.
After the tape is seated on the reel, reITlove the finger and continue
ITlanually turning the take-up reel for 10 or 15 ITlore turns.
NOTE: Do not ITlanually rotate the supply reel while turning
the take-up reel, since friction provides the necessary
windup tension on the take-up reel.
d. Press the VACUUM ON button. Make sure the tape is aligned
properly in the tape feeding guide on each side of the read/write
head, then back off both reels approxiITlately one or two turns to
provide the tape slack for sucking into the loop chaITlbers.
e. Set the tape status switch to either the PERMIT or the PROTECT
position to activate the tape unit for the desired status. If the tape
being ITlounted is to be written on, the plastic write-enable ring
ITlust be in place in the supply reel, and the tape status switch ITlust
be set in the PERMIT position. At the cOITlpletion of the tape
ITlounting procedure, the BOT indicator on the tape unit control
panel is illuITlinated.
Tape Rewinding
1. To perforITl a rewind operation to the beginning-of-tape reflective ITlarker so
that the tape ITlay be deITlounted:
a. Place the tape status switch in the TAPE CHANGE position. The
read/write head rotates upward out of position, and the tape re-
winds onto the supply reel. The rewind proceeds at six tiITles
read/write speed until the reel diaITleter photocell senses light
b.
as the rewind nears cOITlpletion. At this point, the tape decel-
erates to the norITlal read/write speed and continues at this rate
until the beginning-of-tape reflective ITlarker is sensed. When
this occurs, tape ITlotion stops and the tape unit is in a released
condition with the MAIN ON and VACUUM ON indicators illuITlinated.
Press the VACUUM OFF button. This allows the tape unit to cycle
down; i. e. , all ITlotors are de-energized, and loop chaITlber and cap-
stan vaCUUITl are vented, etc., so that the supply reel ITlay be
reITloved.
