ABSTRACT:
A magnetic head having a pair of magnetic core assemblies sandwiching a spacer assembly in a direction of track width includes a laminate consisting of a magnetic material and a nonmagnetic material in a part of the spacer assembly, and the remaining part of the spacer assembly is made of nonmagnetic materials. The spacer assembly is fabricated by forming a plurality of grooves on a surface of a magnetic material block, filling a joint material in the grooves and join the magnetic material block with a nonmagnetic material block to form a composite block, and cutting the composite block to obtain a plurality of spacer assemblies. The spacer assembly together with other elements of the magnetic head is assembled to manufacture a magnetic head.
