Abstract
A method and system provide a magnetic read transducer having an air-bearing surface (ABS). The magnetic transducer includes a first shield, a second shield, and a read sensor between the first shield and the second shield. The read sensor extends along a stripe height direction perpendicular to the ABS. A first portion of the read sensor at the ABS has a first width in a track width direction parallel to the ABS. A second portion of the read sensor is recessed from the ABS along the stripe height direction and has a second width in the track width direction. The second width is greater than the first width.
