Abstract

PURPOSE:To increase the reliability and to enable mass-production, by constituting a tape opposing plane with a plane having a operating magnetic gap, providing a notched part to a core semisphere part to other plane, filling adhesives to it and holding the core semisphere pairs. CONSTITUTION:In a magnetic head 12, a pair of core semispheres 1A, 1B made of an amorphous alloy thin plate constituting an operation magnetic gap g are interposingly located between nonmagnetic guards 2, 2', and a notched part 13 is provided to the core semispheres at both and lower sides other than a tape opposing plane 11 of the gap g, the both nonmagnetic guards 2, 2' are strongly bonded with an adhesives 7 filled in the notch part 13, and the core semispheres 1A, 1B are supported in one body. Through the constitution that the magnetic head 12 is supported in one body with a bonding force between the members 2, 2' without bonding the core semispheres 1A, 1B made of amorphous alloy, a magnetic head with a narrow track width made of an amorphous alloy magnetic member which have been difficult for manufacture can be achieved.
