摘要
PURPOSE:To decrease the chipping, cracking, etc., of insulating films in production process by forming the ridge parts on the converting element forming surface of the thin-film magnetic head to stepped shapes. CONSTITUTION:The plural converting elements 2 and the insulating films 3a, 3b are formed on the prescribed surface of a substrate 1 and this substrate is cut (divided) to respective magnetic head units 14. The ridge part of the converting element surface of each magnetic head 14 in the cut position is constituted to the stepped shape 17. The stepped shape 17 is formed to at least the depth over the entire thickness of the insulating films 3a, 3b. The ridge part of the insulating films 3a, 3b is stepped 17 in this way and the insulating films 3a, 3b are eventually formed to the shape recessed to an inner side and, therefore, the generation of the chipping, cracking, etc., of the insulating films 3a, 3b is decreased.
