Abstract
Devices and/or methods may detect data located in adjacent tracks. A signal representative of a first data unit having a higher signal-to-noise ratio may be detected prior to a signal representative of a second data unit having a lower signal-to-noise ratio, and then may be used to improve the signal representative of the second data unit.
Claims20
A device comprising:
- a storage medium comprising a plurality of data tracks, wherein each of data tracks extends along side of each other;
- and
- a processor operably coupled to the storage medium and configured to:
- acquire a first read data signal representing a first data unit from a first data track;
- acquire a second read data signal representing a second data unit from a second track, wherein first data unit is adjacent the second data unit;
- generate a signal-to-noise ratio for each of the read data signals;
- detect the read data signal having the highest signal-to-noise ratio resulting in a first detected data signal;
- regenerate the read data signal having the lowest signal-to-noise ratio based on the first detected data signal resulting in an improved data signal;
- and
- detect the improved data signal resulting in a second detected data signal.
