A lapping machine comprises a lapping surface plate (1) rotated by a rotating mechanism, a lapping jig (28) having a plurality of projections to bottom surfaces of which a work (30) to be lapped by a lapping surface on the lapping surface plate (1) is fitted, amount-of-projection adjusti
6370763 Manufacturing method for magnetic heads April 16, 2002
Disclosed is a magnetic head manufacturing method for accurately measuring resistance value whereby magnetic heads are processed while measuring the resistance values of process monitoring element. After forming on a wafer magnetic head elements and monitoring element, in which resistanc
6196897 Automatic lapping method and a lapping apparatus using the same March 6, 2001
The present invention relates to an automatic lapping method for lapping a work piece and a lapping apparatus using the same. The lapping apparatus laps a work piece by moving the mounting base 103 relatively to a lapping plate 104. On a coarse processing step, the lapping plate 104 is
6132290 Automatic lapping method of a thin film element and a lapping apparatus using the same October 17, 2000
The present invention relates to an automatic lapping method and a lapping apparatus for lapping a work piece, which is bonded to a row bar, including a thin-film element in order to control the lapping process by accurately measuring height of the work piece. The automatic lapping a
