Abstract

PURPOSE: To smooth an edge of a groove so that a medium is not flawed, by driving to rotate a grinding member provided with a grinding line consisting of an abrasive, which has been formed in a shape of a concentric circle on a substrate, running a magnetic head against the grinding line, and forming a groove on a medium sliding surface of the magnetic head.
CONSTITUTION: In the beginning, grooves 6W8 are not formed on a magnetic head, a sliding surface of the magnetic head is constituted, and thereafter, a shape of the sliding surface is put in order to a desired shape by a method of tape lapping, etc., and also depth of a gap of magnetic poles 4, 5 is formed to a desired value. Subsequently, a discoid grinding member is used for forming the grooves 6W7 of the head sliding surface. The grinding member is provided by sticking in a shape of a concentric circle an abrasive consisting of various kinds of well-known abrasive grains, of polishing lines 13 of a concentric circle shape between then innermost peripheral part 12 and the outermost peripheral part 11, of a base material 10 consisting of a flexible material having a mechanical characteristic being equal to that of a video floppy disk. When working the grooves 6W7, they are formed by making the rotary head on which the sliding surface has been formed to a desired shape coincide with the grinding line 13 of the base material 10 and sliding it.
