Abstract

PURPOSE: To manufacture a multi-element magnetic head with no crosstalk at low cost, by omitting a shield board by winding a core winding part with a tape with shielding effect.
CONSTITUTION: Around magnetic core 2 provided with winding 5, tape 6 with a magnetic body such as Permalloy stuck on the surface of a non-magnetic electric insulating tape is wound several times covering the entire surface of the surface layer of the above-mentioned winding 5. Next, magnetic core 2 mentioned above is built in housing 3" to form a multi-element magnetic head. Since crosstalk is cuased by mutual inductance coupling between windings originally around cores, the above tape 6 is wound around winding 5 to shield almost all parts, so that deterioration in S/N ratio due to the crosstalk can be reduced.
