Abstract: A slider generally comprises a substrate forming at least part of a body of the slider, a heat-assisted media recording (HAMR) read/write transducer proximate the substrate, and an end cap substantially encapsulating the HAMR read/write transducer. The end cap has a first surface proximate the substrate and a second surface as a trailing edge of the slider. The end cap has a first coefficient of thermal expansion (CTE) similar to a corresponding CTE of the substrate. At least a portion of the second surface of the end cap has a second CTE that is lower than the first CTE. A body of the end cap is intermediate to the first and second surfaces of the end cap and has a CTE intermediate of the first and second CTE.

Abstract: Apparatus for recording data and method for making the same. In accordance with some embodiments, a magnetic recording layer is adapted to store data along perpendicular magnetic domains. A protective overcoat layer is formed on the magnetic recording layer to substantially protect the magnetic recording layer from environmental effects. The protective overcoat layer is made of carbon intermixed with at least one transition metal, such as but not limited to chromium.

Abstract: A method comprises sensing for thermal asperities while sequentially scanning a plurality of tracks of a magnetic recording medium in a first direction relative to an inner or outer diameter of the medium. The method comprises halting the scanning at a first track in response to detecting a thermal asperity at the first track, and skipping a predetermined number of tracks in the first direction to a second track. The method also comprises sensing for the thermal asperity while sequentially scanning the plurality of tracks beginning with the second track in a second direction opposite the first direction. The method further comprises halting the scanning at a third track in response to detecting the thermal asperity at the third track, and logging the first and third tracks as tracks between which the thermal asperity is located.

Abstract: A data storage device may be configured with a transducing head separated from a data storage medium by an air bearing. The transducing head and data storage medium are each contained within a housing. The transducing head can consist of a variable resistance sensor that is connected to a temperature module positioned within the housing. One or more operational variables can be measured by the variable resistance sensor to allow an ambient temperature within the housing to be calculated based on a measured operational variable.
