Technologies are described herein that are configured to generate a corrected image by addressing photo response nonuniformity (PRNU) in a camera having a global shutter. A calibration procedure is described, where correction factors for each pixel in an image sensor are computed and subsequently employed to generate improved images.

Systems and methods for generating a corrected image output by a camera having a global shutter

An apparatus is disclosed. The apparatus includes a storage layer, a thermal exchange control layer disposed over the storage layer, and a write layer disposed over the thermal exchange control layer. A Curie temperature of the thermal exchange control layer is lower than a Curie temperature of the storage layer. The Curie temperature of the thermal exchange control layer is lower than a Curie temperature of the write layer.

Heat assisted magnetic recording (HAMR) media with thermal exchange control layer of lower curie temperature

Various magnetic stack embodiments may be constructed with a soft magnetic underlayer (SUL) having a first thickness disposed between a substrate and a magnetic recording layer. A heatsink may have a second thickness and be disposed between the SUL and the magnetic recording layer. The first and second thicknesses may each be tuned to provide predetermined thermal conductivity and magnetic permeability throughout the data media.

Data media with tuned thermal conductivity and magnetic permeability

A magnetic stack includes a heatsink layer comprising (200) Cu or (200) CuX, a magnetic recording layer, and an interlayer disposed between the heatsink layer and the magnetic recording layer.

Heatsink for heat assisted magnetic recording media

A data media may generally be configured in accordance with various embodiments with contactingly adjacent first and second heatsink layers that are tuned with a common crystallographic orientation and with different thermal conductivities to provide a predetermined thermal gradient. The data media may further be configured with a recording layer formed with the common crystallographic orientation adjacent the first and second heatsink layers.
