Abstract:
A data reader may have a magnetoresistive stack with a magnetically free layer decoupled from a first shield by a cap. The cap can have one or more sub-layers respectively configured with a thickness of 4 nm or less as measured parallel to a longitudinal axis of the magnetoresistive stack on an air bearing surface.

Claim (Index 17):
A method comprising:\n depositing a magnetoresistive stack having a magnetically free layer; forming a cap layer atop the magnetically free layer, the cap having a thickness of 4 nm or less as measured parallel to a longitudinal axis of the magnetoresistive stack on an air bearing surface (ABS), the cap comprising a first material inert to reactive etching; depositing a first mask layer on the cap layer; forming a second mask layer on the first mask layer, the first and second layers being independently definable; patterning the first and second mask layers to a common reduced width as measured perpendicular to a longitudinal axis of the magnetoresistive stack on the ABS; patterning the magnetoresistive stack, the magnetoresistive stack having a reader width as measured perpendicular to a longitudinal axis of the magnetoresistive stack on the ABS, the reader width being greater than the common reduced width; depositing an isolation structure and side shield structure; removing the second mask layer; removing the first mask layer; and depositing a shield in contact with the cap layer, the cap layer decoupling the magnetically free layer from the shield.
