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.
