Magnetic Head Throat Height Calibrator

The method, as depicted, is for precisely controlling the throat height of a magnetic head as it is being lapped.

A slot 10, hereinafter called throat height calibrator, is cut in the top of a core block from which the magnetic head is to be manufactured. The bottom of slot 10 is in the same plane as the high end of the throat tolerance. The throat height calibrator will be in each individual core section as it is sliced out of the core block.

The person lapping each core section to the final throat height and finish will simply observe the slot 10. When the slot is removed, the desired throat height is obtained.
