ABSTRACT:
A magnetic head of a construction, wherein first and second magnetic cores each having a magnetic gap are joined together with first and second non-magnetic structures, and the lamination is such that the first magnetic core is in contact with the second non-magnetic structure, and that the second magnetic core is in contact with the first non-magnetic structure, the magnetic head having its feature in that it is made up of the magnetic core members and the non-magnetic core members which are combined in the form of a letter "W" in its cross-section having mutually parallel and upright leg portions.
A method for manufacturing the magnetic head of the above construction, having its feature in that it comprises the first step of producing a core body having a shape such that an open end part of a combination of the magnetic member and the non-magnetic member is closed; and the second step of placing the core body in an opening or openings formed in a carrier plate, followed by subjecting the core body to the polishing work.
