Abstract:
1. A storage device controller for controlling reading of a track of data from a storage medium, wherein the controller: commands a read head to move among a plurality of positions relative to each of at least one track of data, for obtaining respective track signals at each of the plurality of positions; moves data between an equalization module and a memory via memory inputs and memory outputs, and equalizer inputs and an equalizer output; positions the read head at an initial position relative to the track of data to obtain initial track signals; stores the initial track signals in the memory; positioning the read head at an initial subsequent position relative to the track of data to obtain initial subsequent track signals; stores the initial subsequent track signals in the memory; in an initial equalization, inputs the initial track signals and the initial subsequent track signals to the equalization module to obtain equalized track signals; stores the equalized track signals in the memory; positions the read head at a further subsequent position relative to the track of data to obtain further subsequent track signals; stores the further subsequent track signals in the memory; and in a subsequent equalization, provides previously equalized track signals stored in the memory and the further subsequent track signals to the equalization module to obtain subsequent equalized track signals.
