Abstract: A liquid heating appliance for placement on an induction hob includes a liquid vessel, a ferromagnetic heating plate mounted within the vessel by a lifting mechanism, and a thermally sensitive actuator. The lifting mechanism is operable to move the ferromagnetic heating plate upwards within the vessel in response to the thermally sensitive actuator detecting that the heating plate exceeds a predefined temperature.

Abstract: An axially offset foregrip assembly for a long gun has a grip portion having a first grip axis, with a middle portion of the grip portion configured to be grasped by a hand of a user about the first grip axis. The foregrip assembly also has a coupling portion for coupling between the middle portion of the grip portion and a fore-end of a long gun. The long gun has a barrel having a longitudinal axis and a rear grip having a second grip axis, which together define a vertical barrel plane. The coupling portion is configured to couple the grip portion to the fore-end of the long gun such that the first grip axis is in a vertical grip plane horizontally offset from the vertical barrel plane, with the vertical grip plane and the first grip axis substantially parallel to the vertical barrel plane.

Abstract: A method includes writing first data on a first track of a data storage surface, and storing information for the first data in a memory other than the data storage surface. The method also includes performing a write operation on a second track of the data storage surface after the data is written on the first track. The second track is adjacent to the first track. The method further includes identifying potentially-overwritten sectors of the first track as a result of the performance of the write operation on the second track, and performing a first read operation on the identified potentially-overwritten sectors of the first track after completion of the write operation on the second track. Second data associated with the identified potentially-overwritten sectors is then stored in a solid-state memory, and mirrored to media.

Abstract: Systems and methods for servo zone transition optimization are described. In one embodiment, the storage system device includes a disk drive and a controller. In some embodiments, the controller may be configured to assess at least one operation of a read/write head of the disk drive; and format, based at least in part on the assessing of the read/write head, a disk surface of the disk drive with a first servo zone, a second servo zone, and an overlap region extending between a start point of the second servo zone and an end point of the first servo zone. In some cases, the overlap region starts towards a disk inner diameter (ID) and ends towards a disk outer diameter (OD).

Abstract: An apparatus comprises a laser diode configured to generate light during a write operation. A slider comprises a near-field transducer (NFT) and an optical waveguide. The slider is configured for heat-assisted magnetic recording and to communicate the light to the NFT via the waveguide. A writer heater of the slider is configured to receive power during the write operation. A thermal sensor is situated at or near an air bearing surface of the slider. The thermal sensor is configured to produce a sensor signal in response to sensing back-heating from the medium while the NFT generates heat during a write operation. Circuitry, coupled to the thermal sensor, is configured to compare the sensor signal to a threshold and generate an output signal indicative of degradation of NFT performance in response to the sensor signal exceeding the threshold.

Abstract: A heat-assisted magnetic recording head is moved relative to a magnetic recording medium. The medium comprises a plurality of sectors. The sectors define a plurality of sector groups distributed around a circumference of the medium. The sectors of each sector group are written using different operational currents supplied to a laser diode of the head such that at least one sector from each sector group is written using one of the different operational currents. For each of the different operational currents, an average write performance metric is calculated for all sectors written at each of the different operational currents. A particular operational current of the different operational currents is determined that results in a best average write performance metric.
