ABSTRACT:
A magnetoresistive magnetic head comprising a magnetoresistive film, a pair of hard magnetic material films disposed on the magnetoresistive film, and a pair of leads disposed on the magnetoresistive film for feeding a sense current to the magnetoresistive film, wherein at least a part of each lead is formed between the pair of hard magnetic material films on the magnetoresistive film. According to this construction, generation of unstable magnetization at both ends of the track portion can be suppressed, so that a large reproduction output may be obtained.
