PROCESS FOR PRODUCING A MAGNETIC HEAD

摘要

In a process for producing a magnetic head having improved registry between opposite track width controlling grooves, a magnetic gap forming nonmagnetic thin film (10) is deposited on a first magnetic oxide substrate (9a) made of a magnetic oxide material, and a thin magnetic metal film (11a) is formed over the nonmagnetic thin film. Recording/reproducing track width controlling grooves are formed in the surface of the magnetic oxide substrate, thereby providing a first core half (12a). On a second magnetic oxide substrate (9b) is formed a thin magnetic metal film (11b) to provide a second core half (12b). The two core halves are joined to produce a head block by joining the two thin magnetic metal films. The head block is then sliced to form discrete magnetic heads.
