[REGARDING TRACK SHIFT JIG}
The 8 mm video system employs a high precision
tracking ATF ( auto track finding ) which
instantaneously controls the tape running speed with
the four kinds of pilot signals. In this way, the
tracking adjustment knob becomes unnecessary, and
accurate tracing has become possible,
On the other hand however, there has been difficulty
in adjusting the tape path system with the ATF
method, that is it’ was impossible to make a perfect
adjustment because the ATF automatically corrected
even small head-tracing errors,
Because of this, adjustment is carried out to the tape
path system by using the track shift jig (Ref. No.
J-6080-891-A) *, As the track shift jig forcibly releases
the ATF and sets the tracking amount (track shift)
manually, the adjustment of the tape path system
can easily be carried out,
* Previous track shift & monitor jig (J-6080-851-A)
also can be used, Be sure to use the specified
connector.
