Abstract
A method and system for providing a magnetic transducer is described. The method and system define a magnetoresistive sensor in a track width direction, provide hard bias material(s) adjacent to the sensor in the track width direction, and provide sacrificial capping layer(s) on a portion of the hard bias material(s). The sacrificial capping layer(s) have a first height in a stripe height direction. The method and system also provide a mask for defining a stripe height of the sensor. The mask covers at least part of the sensor and has a second height in the stripe height direction. The second height is less than the first height. The method and system define the stripe height of the sensor while the mask covers the sensor. The sacrificial capping layer(s) are configured to prevent removal of the portion of the hard bias material(s) while the stripe height is defined.
