PURPOSE: To obtain a composite magnetic head which is suitable for tapes which are highly resistive to the magnetic force, by forming the head core by using a specified technology in such a way that a magnetic ferrite is used for the working gap forming surface and a metallic magnetic material having a large saturated magnetic flux density (Bs) for the other main magnetic pathes.

CONSTITUTION: A composite substrate 6 is manufactured by piling up a ferrite plate on the whole surface of a non-magnetic card 1 made of glass, ceramic, etc., and by forming plural parallel ferrite pieces 3 by etching, and then, by filling grooves between the ferrite pieces with a metallic magnetic material layer 5 of sendust, etc., having a Bs which is higher than that of the ferrite. A plural number of the substrate 6 is piled up in layer and a layered body 8 is formed, and the layered body 8 is cut along dotted lines 7 into blocks 9, and then, each block 9 is further cut along dotted lines 10 into core blocks 11 and 12. Then, each head tip 17 is formed in such a way that a groove for winding 14 is installed into each block 11 and gap (g) forming surfaces 14 and 15 are mirror finished, and then, two block cores are united with each other with a spacer between them. Finally, each magnetic head is obtained when the tape contacting surface is polished and a winding is installed. In this way, a composite head having excellent characteristics in both high density recording and reproducing is obtained.
