Abstract: Apparatus and method for managing a data storage device during extended idle conditions of the data storage device in which host access commands are not being received or serviced. In some embodiments, upon detection of an idle condition, a control circuit identifies a selected data transducer of the data storage device and a corresponding initial radial position of the data transducer with respect to an associated rotatable data recording surface. The control circuit performs a serpentine seek operation during the idle condition to gradually advance the selected data transducer in a selected radial direction across the data recording surface beginning at the initial radial position and ending at a final radial position. The serpentine seek operation prevents the transducer from being maintained in a stationary position during the idle condition, reducing the likelihood of damage through thermal asperity contact events, lubrication disturb, wear, etc.

Abstract: Implementations described and claimed herein includes a storage device comprising a transducer heat including at least one pair of read/write elements and a heat shaped to thermally protrude regions of the transducer head including the read/write elements. According to one implementation, the heat element includes at least one conductive portion of locally decreased resistance proximal to and between the pair of read/write elements to direct the thermally protruded close point away from a midpoint between the read/write elements.

Abstract: Method and apparatus for verifying and controlling a clearance distance of an object, such as but not limited to a fly height of a read/write transducer adjacent a recording medium in a data storage device. In accordance with some embodiments, a sensor is used to sense a plurality of patterns from an adjacent surface, with each pattern being written at a different constant frequency. A final clearance distance between the sensor and the surface is established in response to a multi-frequency response ratio from the sensor and a single frequency response ratio from the sensor.
