PURPOSE:To reduce crosstalks of a multi-element thin film magnetic head and, at the same time, to manufacture the magnetic head through a simple process by forming the 1st and 2nd thin films of a magnetic substance on a non-magnetic substrate, then, the 3rd and 4th thin films of the magnetic substance on them in interposing a magnetic gap between them. CONSTITUTION:Holes 12a and 12b for windings are provided through a non-magnetic substrate 11 of ferrite, etc., and the 1st and 2nd thin films 13a and 13b of a magnetic substance, such as ''Sendust'', etc., are formed on the substrate 11. The substrate 11 is covered with a non-magnetic substance 14 and the 3rd and 4th thin films 17a and 17b of the magnetic substance are formed on the non-magnetic substance with magnetic gaps 15a and 15b between the non-magnetic substance 14 and thin films 17a and 17b. Then coils 18a and 18b are wound around them through the holes 12a and 12b. Since the thins films 13a and 17a and 13b and 17b of the magnetic substance having thicknesses of ten to serveral tens micrometer are used as the head core and core facing areas between adjacent magnetic head elements are small and, at the same time, the thin films of the magnetic substance are sufficiently separated trom each other, crosstalks can be minimized sufficiently. Moreover, since the number of the thin films used is small, this magnetic head can be manufactured through simple processes. |
