Abstract: A storage device includes a data degradation management module that tracks a risk of data degradation by incrementing a track write counter of a first data track responsive to each data write command to a second data track, such as a data track directly adjacent to the first data track. If a count of the track write counter exceeds a count threshold, one or more post-write scan operations are performed to assess and/or repair data degradation of the first data track.

Abstract: A laser power applied to a recording head is changed for a plurality of iterations. Each iteration involves, via the recording head at each laser power, writing multiple adjacent tracks to a heat-assisted recording medium and determining a bit error rate for at least one of the adjacent tracks at each laser power. A first laser power is found that achieves a minimum bit error rate of the iterations. An operational value of laser power that is smaller than the first laser power is used during operational recording to reduce adjacent track interference.
