Abstract
Magnetic transducing head, comprising a core of magnetizable material having two slightly spaced limbs defining a transducing gap between them, a bundle of insulated wires of electrically conducting material running parallel to the transducing gap being bonded both to the inside and to the outside of at least one core limb, the ends of the wires of different bundles located on the same side of the core limb being connected together by means of connection wires in such a manner that a plurality of electrical turns is formed.
Claims6
A magnetic transducing head comprising
- two core limbs of magnetizable material, said limbs being spaced to form a transducing gap therebetween, each limb having an inside facing the inside of the other limb, an outside opposing the inside of the respective limb, and a pair of opposed lateral sides between said inside and said outside,
- a bundle of insulated wires bonded to the inside of at least one of said core limbs and extending between the opposed lateral sides thereof, each of said insulated wires having an end at one of said lateral sides,
- a bundle of insulated wires bonded to the outside of said at least one of said core limbs and extending between the opposed lateral sides thereof, each of said insulated wires having an end at said one of said lateral sides,
- connection wires extending across said one lateral side between respective ends, at said one lateral side, of wires in the bundle on the inside and wires in the bundle on the outside to complete the turns of a coil, whereby,
- wire bonding techniques known from integrated circuit technology may be used to connect the connection wires to wire ends in the bundles.
