发明名称 Magnetic head and method for manufacture thereof
摘要 A magnetic head is disclosed in which a pair of magnetic core halves, each having a magnetic metal film formed in the vicinity of at least a substrate surface facing a magnetic recording medium, are abutted to each other for defining a magnetic gap between the magnetic metal films, wherein a recess for forming a coil is formed in an abutting surface of at least one of the magnetic core halves and the coil formed by a thin film forming technique is arranged within the recess. A multi-channel magnetic head is also disclosed which includes a plurality of magnetic heads having different azimuth angles of the magnetic gaps, wherein each magnetic head is formed by abutting a pair of magnetic core halves to each other, each of the magnetic core halves having a magnetic metal film formed in the vicinity of at least a substrate surface facing a magnetic recording medium, for defining a magnetic gap between the magnetic metal films, and wherein a recess for forming a coil is formed in the abutting surface of at least one of the magnetic core halves, and the coil is formed in the recess by thin film forming technique. The methods for producing the magnetic head and the multi-channel magnetic head are also disclosed.
