Abstract
A method of slider machining is disclosed. A slider may be diced out of a row bar. A jet of clean air may dry the slider. A laser, guided by a jet of water, may micro-grind the periphery of the slider. The edges of the slider and the corners of the leading edge may be rounded to a pre-determined radius. The slider may be cleaned with de-ionized water, then dried in a hot oven.
