Abstract

A method of machining a slider (16) for a magnetic head used in a hard disk or a floppy disk in which a groove (11) and a recess can be formed in an arbitrary shape by using a masking material (14) and jetting fine abrasive grains carried by a carrier gas against the slider (16), and the edges of the surface of the slider (16) are rounded when necessary by blending-machining with the fine abrasive grains.
