Method and system for compensating for adjacent tracks during reading of data

A storage controller comprising:

• a device controller;
• and
• a read data channel including a decoder for decoding output of a detector;
• wherein:
• the detector is for reading data requested from a storage medium by said device controller;
• the storage medium has a plurality of tracks of data thereon;
• and
• when said device controller requests data from a current track of data on said storage medium:
• said detector reads an adjacent track of data,
• said decoder decodes data from the adjacent track of data,
• said detector reads data from the current track, and
• said decoder decodes the data read from the current track, based on the decoded data from the adjacent track of data, including deriving an interpolation filter from the decoded data from the adjacent track of data by:
• computing a correlation matrix from the decoded and stored data from the adjacent track of data,
• computing a vector from the data from the current track, and
• multiplying the correlation matrix by the vector.
