ABSTRACT:
A magnetoresistance effect type magnetic transducer head apparatus comprises a magnetoresistance effect sensing element, means for applying a high-frequency magnetic field to the sensing element, means for taking-out an output signal from the sensing element, a filter for taking-out the high-frequency component of the output, and another filter for rectifying the output and taking-out the low-frequency component. The magnetic head apparatus may be constructed as a digital circuit so that a multi-channel apparatus can be easily implemented.
