摘要:
Magnetic recording heads and associated methods of fabrication are disclosed. A magnetic recording head has a first shield and a magnetoresistance (MR) read element formed on the first shield. The first shield has a shield height that is defined by a distance between the air bearing surface (ABS) of the recording head and a back edge of the first shield that is opposite the ABS. The MR read element has a stripe height that is defined by a distance between the air bearing surface (ABS) of the recording head and a back edge of the MR read element that is opposite the ABS. The magnetic recording heads as disclosed herein have a stripe height that is greater than the shield height.
