Abstract
The magnetic head includes an alternative multilayer including a magnetic layer(2) and an insulating layer and has a head gap(9), a glass(10) and a head contact surface(11). The apparatus comprises the steps of: forming a substrate(1,1a) which is a ferrite; forming demagnetic layer(5) on a side of the ferrite which is etched except for the multilayer magnetic layer(4). The manufacturing method includes the process step of etching a side of ferrite, and the process for coating the demagnetic layer(5) on an etching side.
