Abstract
A storage controller includes a device controller and a read data channel. The read data channel includes a decoder for decoding output of a detector, where the detector is for reading data requested from a storage medium by the device controller, and the storage medium has a plurality of tracks of data thereon. When the device controller requests data from a current track of data on the storage device, the detector reads an adjacent track of data, the decoder decodes data from the adjacent track of data, the detector reads data from the current track, and the decoder decodes the data read from the current track, based on the decoded and stored data from the adjacent track of data. A storage system includes a storage medium having a plurality of tracks of data thereon and a storage controller as described above.
