Abstract
A method is provided for manufacturing magnetic heads having excellent magnetic properties comprising the steps of removing a certain thickness of a portion of at least one of the apexes of first and second core halves to form a space therebetween above at least one winding groove, bonding the first and second core halves by filling the space with bonding glass, and applying a first magnetic film on the whole tape sliding surface of the bonded first and second core halves. The first magnetic film is removed from one of the first and second core halves. Then gap material and a second magnetic film are applied in sequence on the whole tape sliding surface. The whole tape sliding surface is lapped until the first magnetic film is exposed, and the second magnetic film is spaced from the first magnetic film by the gap material.
