  • Adaptive mitigation of adjacent track interference (ATI) on a recording medium
    Patent number: 9099155
    Abstract: Apparatus and method for adaptively mitigating adjacent track interference (ATI) effects on a data recording medium. In some embodiments, a write count value is accumulated for a first track responsive to successive writes to a second track on the data recording medium. For each of the successive writes, the accumulated write count value for the first track is incremented by a different variable amount based on temperature. The first track is refreshed responsive to the accumulated write count reaching a selected threshold value.

  • STORAGE MEDIA ASPERITY DETECTION
    Publication number: 20140085745
    Abstract: The present application discloses a transducer head comprising a read element that reads data from a storage media and an asperity sensor that detects a dimension of an asperity on a surface of the storage media using a temperature change at the asperity sensor. The asperity may be one or both of a void in the surface of the storage media and a protrusion from the surface of the storage media.
