Abstract
The method of manufacturing a magnetic head is capable of correctly setting a raw bar, which includes small sliders, on to a supporting jig, machining the raw bars precisely and improving yield of manufacturing sliders. The method comprises the steps of forming a magnetizable layer, on a surface of a substrate whose thickness is greater than a length of said slider; and cutting said wafer into a raw bar after forming the layers.
Claims5
A method of manufacturing a head slider, comprising the steps of:
- forming a magnetizable layer on a surface of a substrate wafer having a thickness greater than a length of the slider;
- cutting said wafer into a plurality of raw bars after forming said layer while said thickness of said wafer is still greater than said length of the slider;
- supporting said plurality of raw bars by a supporting jig;
- arranging dummy sections of said plurality of raw bars in a single direction;
- forming air bearing surface patterns on air bearing surface faces of said plurality of raw bars by photolithography;
- and
- removing said dummy sections from said plurality of raw bars after forming said air bearing surface patterns.
