TG7 Guide Adjustment
1)
Establish the FWD mode. Confirm that tape slack does not
occur in between capstan and TG7 guide. (Specification value:
0.5 mm or less of tape slack) If any tape slack occurs, rotate
the tG7 guide to remove the tape slack.
2)
Establish the REV mode. Confirm that RF waveform at exit
side is normal. (Refer to Fig. 6-2-38.)
3)
If the RF waveform at exit side has abnormality, rotate the TG7
nut by 90 degrees in counter-clockwise direction. Then perform
steps 1) and 2) again.

Check upon Completion of Adjustment
1. Tracking Check
1)
Play the tracking alignment tape (XH2-1A1) (Ref. No. J-18) back.
2)
Confirm that RF waveform has amplitude of about 0.65A (65%)
in the FWD mode taking the waveform amplitude during CUE/
REV mode as A (= 100%). (Refer to Fig. 6-2-39.)
3)
Confirm that difference between the minimum amplitude
(E.min) and the maximum amplitude (E.max) of RF waveform
in the FWD mode is 30% or more taking the waveform
amplitude during CUE (or REV) mode as A (= 100%).

E.min: Minimum amplitude
E.max: Maximum amplitude
(E.min – E.min)
4)
Confirm that the RF waveform does not have excessive
fluctuation.
