Abstract
PURPOSE: To improve the magnetic characteristic of the magnetic head to high frequency though its structure is simple, by forming a groove along the direction in which the magnetic flux flows on the whole in the core.
CONSTITUTION: A groove 11 is provided to the upper face or the lower face, or both the upper and lower surfaces of the head core 10 made of alloy metal such as sendast, etc., so that the winding window 12 is surrounded. When providing the groove 11 on the core 10, the method by which the recess part is provided by scanning the circumference of the winding window 12 with the laser light whose luminous flux has been stopped down to the extent of the groove width W and evaporating the metal of the part irradiated by the light, the photoetching method, the electrospark machining method, etc. are available. In any method, the narrower the groove width W and the groove interval W' are made, and the deeper the groove is made within the allowance of strength, the more satisfactory the characteritic in high frequency is obtained. In this regard, it is not always necessary to make the groove 11 a closed loop, and it is allowable that the groove is disconnected in the vicinity of the magnetic gap 3.
