ABSTRACT:
A read head assembly senses information recorded on magnetic media from tracks having different widths. The read head comprises a magnetoresistive strip which is positioned normal to the direction of movement of the magnetic media. In a preferred embodiment, the magnetoresistive strip includes two pairs of signal conducting leads, one pair of which has a lead spacing approximately equal to a first relatively narrow track width, and the other pair having a spacing approximately equal to a second, relatively wide track width.
