Abstract

A manufacturing method of a flying magnetic head slider includes a step of providing a substrate with a plurality of inductive write head elements formed thereon, each head element having a pair of magnetic poles facing to each other via a magnetic gap, and with a protection layer covering the plurality of inductive write head elements, a step of cutting the substrate to separate into a plurality of bar members, each of the bar members having aligned inductive write head elements, a step of processing the protection layer of each bar member so that a distance from an end edge of the pair of magnetic poles to an edge of a bottom surface of the bar member becomes in a range of 1 to 15 μm, a step of lapping each bottom surface of the bar member, and cutting each bar member to separate into a plurality of individual magnetic head sliders.
