MAGNETO RESISTANCE EFFECTIVE-TYPE MAGNETIC HEAD AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a structure of a magnetic head which prevents electrostatic destruction between a magneto resistance effect film 5 and a lower-part shield film 3 caused in a process, in which a wafer takes an electrical charge, such as an ion milling and so on in the manufacturing process of a magneto resis tance effective type magnetic head, and also provide its manufacturing method. SOLUTION: A through-hole 10 is formed at a part of a lower-part gap film 4 which is formed on the lower-part shield film 3, and the lower-part shield film 3 and the magneto resistance effect film 5 are short-circuited when the magneto resistance effect film 5 is made, and the short-circuiting is maintained in the subsequent manufacturing processes.
