Sony BVH-2000, Operation And Maintenance Manual

Page: 412 / 505

Preliminary Information
A. This adjustment is to make the heads trace the record
pattern of the tape and make
the heads come into contact with the tape properly so
that the tape interchangeability is maintained.
The height or slant of the taper guide, slant guides
(entrance and exit) and guide post 3 must be
adjusted.
The RF waveform
of the tape entrance side must be
adjusted first, and then that of the tape exit side
must be adjusted.
Each
of the taper slant
guide should be adjusted alternately while checking
the RF waveform.
@)
Before turning the slant guide screw,
push the tape lightly and check the direction in
which the slant guide must be moved.
G)
For the relation between the turning direction of
the adjustment screw and direction of
slant guide, see Fig. 10-13.
®
Make as much of the tracking adjustment as possible
by the slant of the slant Be careful
that the flange does not press the tape ex-
cessively when turning the height adiustrnent screw.
(J)
Each height of the guide post 3 and exit slant guide
should be adjusted
while checking the RF waveform.
C. To adjust the height and slant, use phillips screwdriver
for M2.6.
If the tracking cannot be correctly owing to
the wear of the entrance slant guide, exit slant guide or
the tape guide section of the head drum assembly, re-
place the part in acordance with the following section.
