Abstract

A method for manufacturing a magnetic head having a laminated core formed by alternately laminating metal magnetic layers and oxide layers on a non-magnetic substance base to a prescribed thickness. The method includes the steps of, positioning the laminated core in a frame of oxide magnetic substance to form a laminated core block, fusing the laminated core and the frame into one body, cutting the fused body to form a complementary pair of laminated core blocks, forming a groove for coil windings on one of the complementary pair of the laminated core blocks, applying a non-magnetic substance film between the laminated cores of the laminated core blocks to form a magnetic gap, joining the complementary pair of the laminated core blocks together to form a magnetic head block and finishing a surface of the magnetic head block to form a prescribed head surface around the magnetic gap.
