Abstract

A read/write head useful for perpendicular recording includes a magnetoresistive (MR) sensor element 1 positioned between two MR shields 2 and 3. The MR shield 2 has a substantially shorter leg than the MR shield 3. The short leg 3 is used as a shield for the MR sensor during the read mode.
