ABSTRACT:
A process for finishing a disc drive slider in which a pressure generator applies multiple pressures to the back surface of one slider while the front surface of the one slider contacts a lapping surface to form a finished front surface of the slider. The slider is part of a substrate having multiple unfinished sliders formed in it. An etch process is used to etch trenches in the substrate aligned between the sliders and to form webs joining the sliders together. After the sliders are finished by lapping, the webs are removed to separate the sliders. The multiple sliders are conveniently held together during the finishing process and the etching process avoids damage to the sliders.
