Method of manufacturing magnetic head

Abstract

Abstract PURPOSE:To additionally greatly improve the yield and reliability of products by exactly regulating the magnetic recording medium-sliding surfaces of individual magnetic heads having magneto-resistance effect elements to respectively prescribed depth values. CONSTITUTION:Plural pieces of the MR head elements 21 formed with upper layer shielding magnetic materials 3 are collected and disposed in parallel, by which a substrate 22 is produced. This substrate is subjected to grinding by using a grinding surface plate 23 while the bias characteristics of the respective MR elements 1 are measured, by which the surfaces of these elements are regulated to the prescribed head depth values.
