❏ Wrap Adjustment
1. While reproducing 8kHz portion of the Low Speed Test Tape, apply pressure
with a cotton swab to the left side of the head. Observe the level change. If
the level increases by more than 0.5 dB, wrap adjustment is necessary. In the
same way, if the level increases by 0.5 dB when applying pressure from the
right side, wrap adjustment is necessary.
2. Turning the screw marked "W" in Figure 6-9, visually adjust the head so that
the tape approaches and leaves the head gap at approximately the same
angle. If the level increases by more than 0.5dB when pressing on the tape
on the right side of the head, rotate the head clockwise. If the level increases
by more than 0.5dB when pressing the tape on the left side of the head,
rotate the head counterclockwise.
3. Repeat step 1 and confirm that the level increases by less than 0.5 dB.
NOTE: Refer to the § 7.3.2 and § 7.4.4 for azimuth adjustment procedures.
