(3) Check Transitional Operation from RPS to Play
Check transition from RPS mode to play mode :
Using a pre-recorded SP tape, make sure the entry
side of envelope comes to an appropriate steady state
within 3 seconds (as shown in Fig. 5-12).
If the envelope waveform does not reach specified
peak-to peak amplitude within 3 seconds, adjust as
follows :
1) Make sure there is no gap between the supply
roller lower flange and the tape.
If there is a gap, adjust the supply guide roller
again.
2) Change operation mode from the RPS to the play
mode (again) and make sure the entry side of
envelope rises within 3 second.

from RPS to Play Mode
(4) Envelope Check
1) Make recordings on T-120 (E-120) and T-160
(E-180) tape.
Make sure the playback output envelope meets the
specification as shown in Fig. 5-13.
2) Play back a self recorded tape (recording made on
the unit using with T-120 (E-120).
The video envelope should meet the specification
as shown in Fig. 5-13.
In SP mode, (A) should equal (B).
If the head gap is wide, upper cylinder should be
checked.

(5) Tape Wrinkle Check
1) Run the T-160 (E-180) tape in the playback, FPS,
RPS and Pause modes and observe tape wrinkle at
each guide.
2) If excessive tape wrinkle is observed, perform the
following adjustments in Playback mode :
◆
Tape wrinkle at the guide roller S, T section :
Linearity adjustment.
◆
Tape wrinkle at tape guide flange :
ACE head assembly coarse adjustment.
