4-2-3. Head Cable Treatment
Technical Reference Manual
Head cable should be arranged correctly by the clampers with appropriate
margin in length so that the head carriage can move on the guide shafts
smoothly.
(1) Clamp the head cable with cable clamper area of the disk guide so that
the cable has appropriate"looseness when the head carriage is set to
track 00 (rear end of the moving area). The appropriate length of the
head cable from the head carriage output to the cable clamper is
approximately 80mm (see Fig.406).
Also confirm that the head cable do not touch the tail end of the
steel belt.
(2) Thread the head cable through the hole of the disk guide and arrange
it under the chassis to hold with a cord clamper. There should be
no excessive looseness of the cable between the cable clamper and the
cord clamper which may cause undesirable contact of the cable to the
disk when inserted. The cable length between the cable clamper and
the cord clamper is 65mm, approx.
(3) Remove the front bezel according to item 4-5-9. Thread the head cable
along the U-groove of the disk guide and pull it up on the chassis to
connect it to the head connector, J9. The cable length between the
U-groove of the disk guide and the head connector is 25mm, approx.
(see Fig.406).
If the head cable is too long, turn the cable around the cord clamper
under the chassis.
