A method of producing a magnetic head as well as a magnetic head produceable in accordance with the method.

摘要

A method of producing a magnetic head (1), the method being based on the use of at least two ferrite core limbs (2, 3), one of the core limbs being provided with a layer (5, 6) of a material having a higher saturation magnetization than the ferrite of the core limbs, whereafter this core limb with the layer present thereon is structured in one manufacturing step, by means of a reactive ion etching process. In the magnetic head (1) the dimension (a), in a direction parallel to the gap width, of layer (5) is smaller than the corresponding dimension (b) of the facing core limb. The layer (5, 6) and a portion of the core limb (2, 3) under this layer have a trapezoidal cross-section.
