Abstract:
1. A magnetic head, comprising: an upper shield layer; a lower shield layer on which a lead contact portion is provided on the edge of the lower shield layer in a stripe height direction within a same plane, the lead contact portion having a width either being equal to or shorter than a maximum length of the lower shield layer in a track width direction; a magnetoresistive sensor which is formed between the upper shield layer and the lower shield layer; a first lead line which is electrically connected to the lead contact portion of the lower shield layer; and a second lead line which is electrically connected to the upper shield layer, wherein when the upper shield layer is projected on a plane where the lower shield layer exists, the lead contact portion of the lower shield layer is provided in a position not overlapped by the upper shield layer, and sense current flows through the upper shield layer, the magnetoresistive sensor and the lower shield layer.
