Abstract
PURPOSE: To make the gap constitution face uniform, by reducing breaks at the edge of the gap constitution face by polishing.
CONSTITUTION: Wafer N where gap constitution face 9 of width 9 corresponding to a desired track width by plural grooves 6 and 7 is stuck to the sticking plate of the polishing device with surface 1 down, and the surface of the wafer, namely, gap constiution face 9 is polished by the rotated lapping plate. By this polishing, breaks generated at the groove forming time are reduced to make the track width uniform.
