Tape Head Cleaner

       This invention provides a cleaning process for test heads
by lapping the rails of the slider, thereby cleaning the surface, yet
not penetrating deep enough to cause scratching.

      In Fig. 1, the thruster 1 provides the linear movement required
to perform scrubbing when the head 7 (see Fig. 2) is loaded.  The arm
2 is inserted into the thruster at approximately the same height as
the disk registration surface.  The lapping tape 4 is held onto the
arm 2 by the spring-loaded rollers 3.  This tape is actually held off
a portion of the arm 2 by the foam pieces 5 causing a radius to
form.  This allows the tape 4 to penetrate up against the tapered
leading edge of the slider during the cleaning action.

      The thruster extends so that the heads can be loaded at
position 6.  The heads are loaded, and the thruster oscillates back
and forth causing a scrubbing action.  When done, the heads are
unloaded, and the thruster retracts.
