ABSTRACT:
A method of making a magnetic head wherein a metal material is sandwiched between non-magnetic substrates, including the steps of: forming a magnetic metal material at least on one side of a non-magnetic substrate; forming by sputtering a crystallization glass layer at least on one side of a compound substrate prepared by forming an anti-diffusion film on the magnetic metal material; then heat-treating in an oxygen containing atmosphere the compound substrate on which the crystallization glass has been formed; further laminating together a number of the aforesaid compound substrates under pressure and then processing (such as by cutting, grinding, and heat-treating) the laminate.
