Abstract: A data writer can have at least a write pole laterally disposed between first and second side shields and vertically disposed between a wrap-around shield and a front shield. The write pole may be separated from the side shields and the wrap-around shield by a lamination of first and second non-magnetic layers.

Abstract: A recording head includes a layer of plasmonic metal deposited on a surface of the recording head. One or more non-self-supporting layers of crystalline material are attached to the plasmonic metal, the one or more layers of crystalline materials configured to form an active region of a laser. A waveguide is configured to receive plasmons from the laser and direct the plasmons to a recording medium.

Abstract: A mounting surface of a read/write head is prepared to receive an epitaxial layer. The mounting surface is proximate a waveguide of the read/write head, and the waveguide is configured to receive an optical output from the epitaxial layer. The epitaxial layer is transfer printed on to the mounting surface. The mounting surface maintains a vertical alignment between the optical output and the waveguide. The epitaxial layer is processed to form a laser integrated with the read/write head.

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: A sensor may be configured with a nanocrystal that has a nitrogen-vacancy. The nanocrystal can be positioned proximal a magnetic source, mount, and articulable stage. Various embodiments configure the articulable stage configured to align the nanocrystal and the magnetic source along a common axis to sense magnetic fields about the magnetic source with a sub-nanometer resolution.

Abstract: A magnetic element can be configured with a write pole that continuously extends from an air bearing surface along a plane orthogonal to the air bearing surface. A magnetic shield can be separated from the write pole by a first gap distance on the air bearing surface throughout a tip portion of the write pole and by a second gap distance distal the air bearing surface along the plane orthogonal to the air bearing surface along a body portion of the write pole with the first and second gap distances measured parallel to the air bearing surface and the second gap distance being greater than the first gap distance.
