【発明の名称】改良されたコイル導体層を備える薄膜磁気ヘッド
Document Type and Number:
Japanese Patent JP2611867
Kind Code:
B2
Abstract:
A thin film magnetic head in which at least a magnetic layer, a conductor layer constituting a coil and an insulating layer (or layers) are formed and patterned to a predetermined shape on a substrate, wherein the conductor layer is formed of a Cu-Ag alloy of Cu100-xAgx where 0.1=x=10 in atomic percent. The gap surface has a surface irregularity level not exceeding 350 Angstroms at Rmax and the conductor layer has a resistivity of 2 mu OMEGA cm or less even after heat treatment at 450 DEG to 550 DEG C.
