Abstract: A reader of a magnetic recording head includes a sensor stack, a first side shield and a second side shield disposed on opposite sides of the sensor stack in a cross-track dimension, and a bridge. The bridge is configured to align magnetic moments of the first side shield and the second side shield. The bridge is disposed above the sensor stack relative to a media-facing surface of the magnetic recording head and proximate to the first side shield and the second side shield.

Abstract: A recording head that includes a reader having a front end at a bearing surface of the recording head and a rear end behind the bearing surface. The reader has a non-rectangular shape with a front-end width that is less than an average width of the reader. A first bias element is positioned proximate to a first side of the reader, and a second bias element is positioned proximate to a second side of the reader. Each of the first and second bias elements has a bias level that is a function of a ratio of the front-end width to the average width of the reader.

Abstract: A method of forming a read head. The method includes forming first and second read sensors that are substantially trapezoidal in shape. A first read measurement is performed on a storage medium using the first read sensor. A second read measurement is performed on the storage medium using the second read sensor. Based on a comparison of the first and second read measurements to a predetermined quantity, either the first read sensor or the second read sensor is selected to be operational in a data storage device.

Abstract: A reader includes a bearing surface and a free layer having a front surface that forms a portion of the bearing surface. The reader also includes a synthetic antiferromagnetic (SAF) structure below the free layer, the SAF structure has a narrow portion with a front surface that forms a portion of the bearing surface and a wide portion behind the narrow portion. The reader further includes an antiferromagnetic (AFM) layer in contact with the wide portion of the SAF structure. The SAF structure is configured to prevent switching from one magnetic state to another magnetic state in the wide portion under thermal fluctuations.

Abstract: A reader having a sensor stack and a top shield above the sensor stack. The top shield has an upper surface and a lower surface. The reader also includes at least one side shield below the top shield and adjacent to the sensor stack. The reader further includes a decoupling layer between the upper surface of the top shield and the at least one side shield. The decoupling layer is configured to decouple a first portion of the at least one side shield, proximate to the sensor stack, from at least a portion of the top shield.
