Resistance pattern for gap depth machining of thin film magnetic head and gap depth machining method

摘要

The present invention relates to a resistance pattern for gap depth processing of a thin film magnetic head and a gap depth processing method using the same, and more specifically, a rectangular main resistance pattern 15 for position detection and two terminal patterns for an external pattern. (16) and by using a resistance pattern consisting of an internal wiring pattern 17 connecting the terminal pattern 16 and the main resistance pattern 15 to short-circuit the terminal pattern at the final machining position by using the existing resistance pattern The gap depth of the thin film magnetic head, which can control the gap depth of the thin film magnetic head with precision that requires more accuracy than the processing method, and can manufacture the thin film magnetic head with high reliability in the machining process, and the resistance pattern for processing and the gap depth using the same It relates to a processing method.
