Abstract: Technologies are described herein for adapting channel parameters of a read channel in a transformed space. A set of channel parameter values associated with one or more components of the read channel is received. A general transformation is performed on the channel parameter values, and insignificant terms in the transformed space are filtered out. Next, an inverse transformation is performed on the filtered terms in the transformed space to calculate a new set of channel parameter values for the component(s).

Abstract: A storage device is configured to utilize different encoding and decoding schemes in reading and writing data to different regions of a storage device based on the position of the storage regions and/or component-specific physical characteristics of the regions. Each encoding scheme may include multiple different types of encoders selected based an optimization process for each region.

Abstract: Technologies are described herein for utilizing multiple, wide readers to read narrow data tracks on a magnetic recording media in a storage device. A system for reading a data track on a magnetic recording media comprises a plurality of reader elements and a multi-reader decoder module operably connected to the plurality of reader elements. Each of the reader elements is configured to read a magnetic signal from the magnetic recording media. Each reader element may be wider than a width of the data track on the recording media. The multi-reader decoder module is configured to receive a read signal from each of the reader elements, and decode the data on the data track based on the read signals from the reader elements.

Abstract: Various aspects of the present disclosure are directed toward an apparatus, such as a disc drive, including a disc having multiple tracks, a magneto-resistive transducer assembly, and multiple-track signal correction circuitry. The multiple-track signal correction circuitry compensates for asymmetry in a readback signal of read data stored in at least one of multiple tracks based on different correction coefficients for respective ones of the multiple tracks.
