Track-edge noise in a written track and a partially dc-erased track was analyzed to clarify the edge noise properties of a side-erased band. It was found that the track-edge noise power and its noise components in a partially erased track are equal to those in a written track. The track-edge noise power in a side-erased band is the summation of the transition-edge noise power of old track, the overwritten track, and the bit-edge noise power.
