Abstract
A giant magnetoresistive (GMR) sensor for reading information from a magnetic storage medium has a first non-magnetoresistive layer, a first magnetoresistive layer formed on the first non-magnetoresistive layer, a second non-magnetoresitive layer formed on the first magnetoresistive layer, a second magnetoresistive layer formed on the second non-magnetoresistive layer, and a third non-magnetoresistive layer formed on the second magnetoresistive layer. The first non-magnetoresistive layer is provided with a single step on a surface of the first non-magnetoresistive layer. The step has an edge extending in a direction substantially parallel to a plane of a working surface of the GMR sensor.
