Abstract
PURPOSE: To perform erasing efficiently with less erase current for alloy tapes of high coercive force by constituting the head with a rear part core body composed of sintered ferrite of E shape and a front core body composed of 3 pieces of Sendust alloy bodies.
CONSTITUTION: The magnetic head is divided to a front core body 4 and a rear core body 5, the front core body 4 being constituted by a Sendust alloy body and the rear core body 5 by sintered ferrite. The rear core body 5 is molded to an E shape so that its three leg parts 6a thru 6c become of integral construction. A bobbin body 7 having been would with winding is inserted onto the central leg part 6b of these leg parts. The front core body 4 comprises molding three Sendust alloy bodies 8a thru 8c to suitable shapes in corresondence to the three leg parts of the rear core bodies and respectively opposedly bonding the Sendust alloy bodies 8a thru 8c of the front core body 4 and the leg parts 6a thru 6c of the rear core body 5. Thereby, erasing may be performed efficiently with less erase current.
