Abstract: A data storage system may have at least one data writer that incorporates a write pole that continuously extends from an air bearing surface. The write pole can be separated from the air bearing surface by a side shield that consists of a first magnetic layer positioned on the air bearing surface and a guard layer separated from the air bearing surface by the first magnetic layer. The guard layer may be configured with a different magnetic saturation flux density than the first magnetic layer.

Abstract: Data storage systems having barriers that may reduce erasure flux and increase write-ability are provided. Data storage systems include a writing element. The writing element has a write pole with a flare region. A magnetic flux barrier is located along the write pole flare region. The magnetic flux barrier is illustratively made from an in-plane magnetically anisotropic material that has an easy plane of magnetization. In another embodiment, a data storage system includes a writing element having an air bearing surface and a shield at the air bearing surface. The shield has a magnetic permeability of approximately zero. The shield illustratively includes alternating layers of positive and negative permeabilities. The shield optionally includes a plurality of shields that may include top, bottom, and side shields.

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: The presently disclosed technology teaches integrating disc drive electronics into a transducer head. Decreased electrical transit times and data processing times can be achieved by placing the electronics on or within the transducer head because electrical connections may be made physically shorter than in conventional systems. The electronics may include one or more of a control system circuit, a write driver, and/or a data buffer. The control system circuit generates a modified clock signal that has a fixed relation to phase and frequency of a bit-detected reference signal that corresponds to positions of patterned bits on the disc. The write driver writes outgoing data bits received from an external connection to off-head electronics directly to the writer synchronized with the modified clock signal. The data buffer stores and converts digital data bits sent from the off-head electronics to an analog signal that is synchronized with the modified clock signal.

Abstract: A disk drive has a recording head slidably coupled to a rail and in magnetic communication with a disk surface. The recording head has an optical power interface and an optical data interface. An optical transceiver is fixably mounted proximate an end of the rail and optically coupled to the optical power interface and/or the optical data interface of the recording head. The coupling between the optical transceiver and the interfaces facilitates writing data to the disk surface and/or reading data from the disk surface via the recording head.

Abstract: A recording head comprises a write pole extending to an air-bearing surface. A near-field transducer is positioned proximate a first side of the write pole in a down-track direction. A heatsink structure is proximate the near-field transducer and positioned between the near-field transducer and the write pole. The heatsink structure extends beyond the near-field transducer in a cross-track direction and extends in a direction normal to the air-bearing surface.
