Abstract
A magnetoresistive (MR) sensor shield shields against both down track and cross-track interference. The shield can be formed in a single deposition step. In one implementation of the disclosed technology, a “tail” portion of the shield is eliminated by including a non-magnetic material adjacent to opposite sides of a middle portion of the sensor stack.
