3-5. TG1 Height Adjustment
1) Replay the tracking standard (XH2-1A1) (Ref. No. J-12).
2) Confirm that the waveform of the tape path is flat.
(Refer to Fig. 6-2-11, and 6-2-12.)
3) Confirm to see that there are gaps between top edge of the
tape and the TG1 flange, and bottom edge and the TG1 flange.
(Refer to Fig. 6-2-13.)
If the top and/or the bottom edge of the tape contacts with
TG1 flange, adjust the height of the TG1 so that there is gap
between the edge of the tape and the flange.
If the height of the TG1 is adjusted, check the entrance side of
the tape path waveform (refer to Fig. 6-2-11, and 6-2-12). If
there is any change in the entrance side of the tape path wave-
form, re-adjust the entrance side (TG2). (Refer to “3-4. TG2/
TG4 Guide Fine Adjustment.)

3-4. TG2/TG4 Guide Fine Adjustment
1) Play back the tracking standard (XH2-1A1) (Ref. No. J-12).
2) Adjust the TG2 so that the RF envelope has the larger ampli-
tude at the entrance side first, than adjust TG2 guide for flat
amplitude. (Refer to Fig. 6-2-11.)
3) Adjust the TG4 so that the RF envelope has the larger ampli-
tude at the exit side first, than adjust TG4 guide for flat ampli-
tude. (Refer to Fig. 6-2-12.)
