PROBLEM TO BE SOLVED: To prevent needless ruggedness from being formed on an ABS plane by etching for processing a slider ABS plane even when a gap layer is constituted of a non-alumina base non-magnetic material being a different kind from a constitution material of a substrate. SOLUTION: Many thin film magnetic head elements 3 consisting of plural constitution layers including magnetic gap layers 8, 11, 13 constituted of a non-magnetic material are formed in a lattice arrangement state on a wafer surface. In such a forming process of the elements 3, a constitution material of the magnetic gear layers 8, 11, 13 existing in a region to which etching for processing a slider shape is performed is previously eliminated. Then, the wafer on which the elements 3 are formed is cut for every head block, and slider shape processing of a plane 20 opposed to a magnetic recording medium constituted of cut planes of the head block is performed by etching. |
