Float lapping fixture.

摘要

Described is a technique and associated fixture for lapping magnetic recording heads in a group such that each head is mounted on a "free floating" part in the fixture (F,F1), being biased for lapping only by the weight of this part and being individually removable during lapping mode; and also characterized by capability for pivoting the fixture to change the lap-angle of all such heads in common to a new constant prescribed angle, the parts also being selectibly kept non-rotatable in the fixture.
