MAGNETO-RESISTIVE READING HEAD

摘要

A magnetic reading head having a magneto-resistive element of the non-magnetically biased type, in which the current is forced to flow through the element at an angle with the easy axis of magnetization. For adjusting the dynamic range of the element (for example, in behalf of the application of different types of tape) means are present to subject the element to an auxiliary field the strength of which can be varied and the direction of which is parallel to the easy axis of magnetization.
