1) Full Track Erase Head
At playback mode, loosen head height control
screws (a) (a’), and adjust so that the tape is
equi-distant in relation to the protruding top and
bottom edges of the full track erase head core
(width between top edge of tape and top edge
of head core is the same as the distance between
the bottom edge of the tape and the bottom
edge of the head core).
2) 4-track Erase Head
At playback mode, loosen head height control
screws (b) (b’) shown in Fig. 16, and adjust so
that the upper edge of the tape is about 0.1 mm

3) Recording Head
At playback mode, adjust recording head height
by turning head height control screws (c), (d), (e)
shown in Fig. 16 to left and right until the upper
edge of the tape is the same height as the upper
edge of track-1 head core of the recording head.
At this time confirm that the lower edge of the
tape is also the same height as the lower edge
of track-4 head core of the recording head.
4) Playback Head
With head height control screws (f) (g) (h) shown
in Fig. 16, adjust the playback head height in
the same way as outlined above for recording
head.
5) After the various head height adjustments have
been made, confirm that the core side of the
heads are at right angles with the chassis during
tape travel.
