A magnetic device includes a write element having a write element tip that defines a medium confronting surface. The write element is operable to generate a first field at the medium confronting surface. A conductor is proximate the write element tip and first and second conductive leads are connected to the conductor and configured to deliver a current to the conductor to generate a second field that augments the first field. First and second side elements are disposed on opposite sides of the write element tip in a cross-track direction at the medium confronting surface. At least a portion of the first conductive lead is disposed adjacent the first side element on a side opposite the medium confronting surface, and at least a portion of the second conductive lead is disposed adjacent the second side element on a side opposite the medium confronting surface.

A method includes activating a stress-effecting layer of a thin film structure, having the stress effecting layer adjacent to a magnetic layer, to induce a magneto-elastic anisotropy in the magnetic layer.

Magneto-elastic anisotropy assisted thin film structure

An apparatus comprises a storage medium, a recording head, a source of electromagnetic radiation, and a control circuit for modulating the source of electromagnetic radiation in response to a static deviation of a spacing between the recording head and the storage medium. A method of compensating a static deviation of a spacing between a recording head and a storage medium performed by the apparatus, and a method of precompensating for nonlinear transition shifts in a heat assisted magnetic recording system, are also provided.

Compensating the effects of static head-media spacing variations and nonlinear transition shift in heat assisted magnetic recording

A thin film structure, such as a magnetic recording media, having a magnetic layer and a stress-effecting layer is disclosed. The stress-effecting layer induces a magneto-elastic anisotropy in the magnetic layer. The stress-effecting layer can be activated by the application of an external stress and/or strain. The induced magneto-elastic anisotropy can transiently achieve and/or enhance a tilt angle of the medium. The medium can be a perpendicular magnetic recording medium, a longitudinal magnetic recording medium and/or a tilted magnetic recording medium. The magnetic recording media is suitable for use with a data storage system, such as a HAMR data storage system.

A sensing contact probe includes a beam support and a probe. The probe has a bent beam body that extends from the beam support to a probe tip face that has a position and faces in an angular direction. The bent beam body has first and second beam layers bonded together and have differing residual stresses that bend the beam body. A stress relief region is formed in the bent beam body. The stress relief region has an adjusted stress property that adjusts the bending to control the probe tip face position and angular direction.
