4-4. ADJUSTMENT OF MECHANISM TAPE TRAVEL SYSTEM
4-4-1. Preparation for adjustment
(1) Clean the tape running areas (guide poles, rollers, drum, Capstan shaft, Pinch roller) (Figure 1)
(2) Connect the oscilloscope to the following TPs.
RF output ... TL3306
H-SW-P ...... TL405
GND ........... TL3318
(3) Playback the alignment tape (VR2DBOPS).
(4) Ascertain that each guide is free from remarkable curl.
(5) Ascertain that the RF waveform of inlet and outlet sides is flat on the oscilloscope (Figure 2, (a)). Unless the waveform
is flat, (Figure 2, (b), (c)), make an adjustment as follows.
4-4-2. Adjusting the Sup GR and Tu GR
(1) Turn the Sup and Tu guide rollers to get the flat waveform at the inlet and outlet sides.
