Abstract:
1. A magnetic read transducer having an air-bearing surface (ABS) and comprising: a first shield; a magnetoresistive sensor including a sensor layer, the sensor layer having at least one edge in the track width direction along the ABS; at least one soft magnetic side shield adjacent to the at least one edge, the at least one soft magnetic side shield having a full film permeability of at least ten; a second shield, the magnetoresistive sensor residing between the first shield and the second shield such that the first shield and the second shield reside in a direction substantially perpendicular to the track width direction from the magnetoresistive sensor, the magnetoresistive sensor being free of an in-stack hard bias layer; and wherein the at least one soft magnetic side shield is magnetically coupled and physically connected with at least one of the first shield and the second shield.
