摘要： A method of fabricating a multi-element magnetic head core is provided in which a plurality of first grooves are formed in a surface of a magnetic block to form a plurality of magnetic circuits, a plurality of second grooves are formed in this surface in directions perpendicular to the first grooves to separate the magnetic circuits from each other, the first and second grooves are filled with a non-magnetic material, the magnetic block is then cut along lines parallel to the second grooves to obtain a plurality of core blocks, and a third groove is formed in each core block from a side wall thereof to isolate the magnetic circuits completely from each other. According to this method, the number of fabrication steps required for forming a multi-element magnetic head core can be reduced, and moreover a multiplicity of magnetic head cores can be formed at the same time.

摘要： A magnetic recording/reproducing head assembly comprising a first magnetic path forming member on which a coil is mounted, a second magnetic path forming member which forms a magnetic path in cooperation with the first magnetic path forming member, and a film laminate formed at a front gap portion between the first magnetic path forming member and the second magnetic path forming member. The film laminate includes a magnetic detecting element for detecting a change in a magnetic field and a soft magnetic film or films. This magnetic head assembly is prepared by forming the film laminate on a head base of the head assembly, bonding a core member to the head base with the film laminate formed thereon, and mounting a coil on the core member.
