Abstract: A data sensor may be configured in accordance with some embodiments to have a magnetically responsive stack that contacts at least one shield. The at least one shield may be constructed with a non-rectangular shaped electrical contact, such as a triangular and trapezoidal shape, respectively positioned on top and bottom shields on opposite sides of the magnetically responsive stack.

Abstract: A heat-assisted magnetic recording head includes a laser, a near-field transducer, a primary waveguide, a secondary waveguide, and a photodiode. The laser is configured to emit electromagnetic radiation. The near-field transducer is configured to focus and emit an optical near-field. The primary waveguide configured to receive the electromagnetic radiation and propagate the electromagnetic radiation toward and proximal to the near-field transducer. The secondary waveguide configured to receive a portion of the electromagnetic radiation from the primary waveguide. The photodiode configured to receive the portion of the electromagnetic radiation from the secondary waveguide and emit a signal that represents a magnitude of the electromagnetic radiation that the laser emits.

Abstract: A data storage device may be constructed to sense data bits with at least a magnetic stack contacting a shield that has a horizontal lamination of magnetic and non-magnetic layers. The magnetic layer may be configured with a first width at an air bearing surface (ABS) that defines a first aspect ratio and a different second width that defines a different second aspect ratio distal the ABS.

Abstract: A dual-slot waveguide receives energy from a coupling waveguide. The dual-slot waveguide includes first and second light propagating regions of low-index material located side-by-side in a direction normal to a light propagation direction. Inner sides of the first and second light propagating regions are separated by a first region of a high-index material. Second and third regions of the high-index material surround outer sides of the first and second light propagating regions. A near-field transducer receives portions of the energy from the first and second light propagating regions.

Abstract: Implementations disclosed herein allow a signal detected by a magnetoresistive (MR) sensor to be improved by providing for a region of reduced anisotropy within a synthetic antiferromagnetic (SAF) shield. The SAF shield includes first and second layers of ferromagnetic material separated by a coupling spacer layer. A distance between the first and second layers of ferromagnetic material is greater in a region proximal to the sensor stack than in a region away from the sensor stack.
