Abstract:
A magnetoresistive head for reading data from a magnetic media comprising: a magnetoresistive element extending into the head from an air bearing surface of the head, the air bearing surface being arranged to fly the head a design distance from the media moving relative to the head at a design velocity; and a selectively-etched recess extending from the air bearing surface into the magnetoresistive head for determining a design height of the magnetoresistive element, wherein the magnetoresistive element extends into the head a design extent from the air bearing surface and the selectively-etched recess comprises a recess in the magnetoresistive element extending from the air bearing surface into the head, the recess having a design depth into the air bearing surface to define a selected height to the magnetoresistive element between the extent of the magnetoresistive element and the recess.
