Abstract

PURPOSE:To obtain a magnetic head for a magnetic tape, such as an alloy tape, having high coercive force easily and efficiently, by slicing and polishing a block body obtained by joining a magnetic member which has high saturated magnetic flux density with another magnetic member which has less high frequency loss. CONSTITUTION:The 1st magnetic member 5, such as Fe-Al-Si alloy with high - saturated magnetic flux density, which has greater thickness than the depth of the front gap of a magnetic head is joined with the top surface of the 2nd magnetic member (ferrite, etc.) 6 which has less high frequency loss, thus forming a block A. The block A is sliced (S1, S2...Sn) in parallel, at prescribed intervals T and at an angle theta into blocks B, and after the sliced surface 6' of the block B is polished and a groove 7 is formed, the block B is sliced in parallel to W track width size, thus obtaining a core member C. The member C is provided with winding 8, and two members are bonded together with a gap spacer 9 between to form a magnetic head. Thus, mass-producibility is improved.
