An apparatus has a substrate. A laser is deposited above the substrate. The laser comprises one or more non-self-supporting layers of crystalline material. A first layer is disposed proximate the laser. The first layer is deposited using a first process. A second layer is disposed proximate the second layer. The second layer is deposited using a second process different than the first process. The first layer and the second layer are configured to mitigate mechanical stress in the laser. A waveguide is deposited proximate the laser. The waveguide is configured to receive plasmons from the laser and direct the plasmons to a recording medium.

Laser stress mitigation for heat-assisted magnetic recording

A data reader may consist of at least a magnetoresistive stack positioned on an air bearing surface. A portion of the magnetoresistive stack may be set to a first fixed magnetization by a pinning structure separated from the air bearing surface by a front shield that is set to a second fixed magnetization by a biasing structure. The front shield may be separated from the biasing structure by a coupling structure.

Data reader with front shield coupling structure

A data reader may have a magnetoresistive stack consisting of at least magnetically free and magnetically fixed structures with the magnetically fixed structure set to a first magnetization direction by a pinning structure separated from an air bearing surface by a front shield portion of a magnetic shield. The pinning structure can meet the front shield portion with a planar sidewall angled at 10&#xb0; or less with respect to the ABS.

A write pole structure includes a write pole and a trailing shield wherein the write pole includes a high magnetic moment (HMM) material layer on a surface of the write pole facing the trailing shield, wherein the HMM material layer includes a laminated layer including a rare earth material layer and a transition metal layer.

A magnetic sensor may generally be configured as a data reader capable of sensing data bits from an adjacent data storage medium. Various embodiments of a magnetic element may have at least a magnetic stack that contacts at least a first shield. The first shield can have at least one synthetic antiferromagnetic structure (SAFS) that is pinned by a high-coercivity ferromagnetic (HCFM) layer.
