Abstract: A head assembly includes a submount, a body with a first surface, an optical path, a near field transducer (NFT), a sensor, and a laser. The optical path is disposed in the body and is adapted to receive light and convey the light to a distal end of the waveguide. The near field transducer (NFT) is disposed adjacent the distal end of the waveguide and has an output end proximate the first surface of the body. The sensor interfaces with the submount and the laser is attached to the submount along a non-primary lasing surface. The laser is adapted to inject light into the waveguide and includes a grating adapted to diffract a portion of the light through the non-primary lasing surface to the sensor.

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.
