(4) Adjustment of Azimuth of Magnetic Recording/Playback Head:
* Adjust the position of Fig. 28-1 so that Fig. 28-1 may
position about 0.2mm lower from the assumed film path.
In practice, put a plastic ruler on Fig. 28-3 and 5» and
adjust Fig. 28-1 by turning Fig. 28-6 so that Fig. 28-1 may
slightly touch the ruler.
Next, move Fig. 28-1 about 0.2mm towards Fig. 28-2 by turning
Fig. 28-6 counterclockwise.
Note: Unless Fig. 28-1 is fixed at proper position, it
causes the below-mentioned troubles and gives bad
influence upon Sound Quality (Wow/Flutter, Frequency
Response, etc.).
(a) Film sags
(b) Untouch or unstable head-touch of Sound Track
So use best care to keep proper position of Fig. 28-1.
* Adjust the position of Fig. 28-1 by turning Fig. 28-4 so that
the center of Fig. 28-1 may coincide with the center line of
Fig. 28-2 ((w) in Fig. 28).
* Adjust the distance between Fig. 28-1 and 8 ((x) in Fig. 28)
to be about 2.5mni by turning Fig. 28-7x3> and load a film.
Readjust the position of Fig. 28-1 by turning Fig. 28-7x3
slightly so that Fig. 28-1 may locate at the correct position
against magnetic sound track.
Make certain that Fig. 28-1 may not interfere with picture.
* Running 7,000Hz Test Film such as SMPTE TEST FILM (M16AL
AZIMUTH ALIGNMENT, 7»000HZ), adjust the position of Fig. 28-1
by turning Fig. 28-7x3 so that the maximum output power may
be achieved.
After the adjustment, fix Fig. 28-7x3 with adhesive.
