Abstract

PURPOSE:To obtain the titled magnetic head which is small in size and suitable for recording and reproduction with high density, by making both magnetic gap intervals small enough, in a composite head which is formed as one body a recording/reproducing head and an erasing head. CONSTITUTION:A recording/reproducing head is constituted of first and second magnetic cores 5, 6a of a base body of a high magnetic permeability material, in which a coil groove 4 is formed, a gap spacer 7 of SiO2, and a reinforcing part 8. Also, an erasing head is constituted of the second magnetic core 6a, a third magnetic core 11 consisting of a base body of a high magnetic permeability material, in which a coil groove 10 is formed, a gap spacer 13 of SiO2, etc. interposed between both the magnetic cores 6a, 11, and the reinforcing part 8 of glass, etc. The head for recording and reproduction, and erasion uses the second magnetic core 6a jointly, goes to a structure in which a gap interval between the recording/reproduction use magnetic core and the erasion use core is shortened, since no non-magnetic material is provided, and accordingly, a composite magnetic head being small in size and suitable for a high density recording/reproducing device is obtained.
