ABSTRACT:
This invention teaches a method for producing small machined parts by laser including a description of how to avoid sensitive edges of the work piece being machined and how to control beam size for maintaining uniform cavity depth over a relatively long work piece and also how to generate non-uniform cavity depth profiles on the surface of one or more parts. The invention also teaches that such a process can be used to produce satisfactory negative pressure air bearing sliders which are used to support the transducing magnetic heads for high density magnetic storage disk drives.
