摘要： According to one embodiment, a storage device includes a recording medium, a head slider, a head suspension, an actuator, and an alternating current component generator. The head slider faces a surface of the recording medium. The head suspension supports the head slider. The actuator is incorporated in the head slider and increases the protruding length of a protrusion formed on the head slider toward the surface of the recording medium based on an increase in a supplied electrical signal. The alternating current component generator superimposes an alternating current component having a frequency equal to the natural frequency of the head suspension over the electrical signal while increasing or decreasing the protruding length of the protrusion at a predetermined amplitude.

摘要： Data in a storage medium is scanned while a storage device is in an idle state. A proportion of scanned data in entire data in the storage medium is compared with a threshold value. If the proportion of the scanned data is less than the threshold value, an unscanned data in the storage medium is scanned during a time interval between commands received by the storage device from outside. The process is repeated until the proportion of the scanned data is equal to or more than the threshold value.
