Abstract: The disclosure is related to systems and methods for temperature-based device operation. In one example, a device may include a first memory and a temperature detection module adapted to measure a temperature of the device and modify a data storage behavior of the first memory based on the temperature. The device may further comprise a second memory, and the temperature detection module may direct that data be written to the first memory less frequently, and be written to the second memory more frequently when a threshold temperature is exceeded. The temperature detection module may also implement operating limitations for the device when a threshold temperature is exceeded, such as restricting execution of background diagnostics or implementing other operating limitations. In some embodiments, other environmental factors such as humidity, altitude, air pressure, physical shock, or other factors may be monitored and the device operation may be modified based on those factors.

Abstract: An apparatus includes a write element configured to apply a magnetic field to write data on a portion of a heat-assisted magnetic recording media in response to an energizing current. An energy source is configured to heat the portion of the media being magnetized by the write element. A preheat energizing current is applied to the write element during an interval before writing the data to the portion of the media. The preheat energizing current does not cause data to be written to the media and brings at least one of the write element and driver circuitry into thermal equilibrium prior to writing the data on the portion.

Abstract: A transducer includes a spin valve ("SV") structure comprising a pinned ferromagnetic layer adjoining a first end portion thereof and a freely rotating ferromagnetic layer adjoining an oppositely disposed second end portion thereof. First and second current conductors adjoin the first and second end portions of the spin valve structure respectively in a current perpendicular-to-the-plane configuration ("CPP"). In a particular embodiment disclosed herein, a differential CPP transducer includes a pair of SV structures having first and second current conductors with a common current conductor intermediate the SV structures.
