Patent ID: 8793543

Claim:
A device operable to provide one or more read comparison signal values for reading data from a storage medium, the device comprising: a characterization module including a plurality of characterization vectors, wherein each characterization vector corresponds to a respective set of one or more storage medium characterization parameter values, and includes a first set of one or more read comparison signal values and a second set of one or more read comparison signal values, the second set corresponding to the first set and a respective pair of transition probabilities associated with the set of one or more storage medium characterization parameter values; a selection module to select a characterization vector based on a specified set of one or more storage medium characterization parameter values; and a read controller to: provide the first set of one or more read comparison signal values, from the selected characterization vector, to read circuitry associated with the storage medium; and provide the second set of one or more read comparison signal values, from the selected characterization vector, to read circuitry associated with the storage medium.
