Verfahren zur Herstellung eines Ferritmagnetkopfkernes.

摘要

A method of producing a ferrite magnetic head core (10) having a flux gap (14) in the magnetic flux path thereof, in which the head core is cut from a bar (20) having an O-shaped cross section and comprising first and second ferrite pieces (25, 26) having opposed faces (34, 35) including the flux gap there-between, comprises depositing a hard non-magnetic layer (14) as a gap material on the face of one of the ferrite pieces. A layer (31, 40) of a magnetic material of the type which can be bonded to ferrite by heat and pressure is then sputter deposited on the gap material. The layer of magnetic material is then bonded to the face of the other of the ferrite pieces by the application of heat and pressure below a point which may affect the ferrite's magnetic characteristics.
