Abstract
Systems and method relating generally to data processing, and more particularly to systems and methods for utilizing multiple data streams for data recovery from a storage device.
Claims20
A data access system, the system comprising:
- a head including a first read sensor, a second read sensor and a third read sensor,
- a read processing circuit including:
- a first combining circuit operable to generate a first unified data set based upon information received from the first read sensor and information received from the second read sensor;
- a second combining circuit operable to generate a second unified data set based upon information received from the second read sensor and information received from the third read sensor;
- and
- a merging circuit operable to assemble a first portion of a codeword derived from the first unified data set with a second portion of the same codeword derived from the first unified data set to yield a processing codeword.

A method for data processing, the method comprising:
- flying a sensor head over a storage medium, wherein the head includes a first read sensor, a second read sensor and a third read sensor;
- combining information received from the first read sensor and information received from the second read sensor to yield a first unified data set;
- combining information received from the second read sensor and information received from the third read sensor to yield a second unified data set;
- and
- merging a first portion of a codeword derived from the first unified data set with a second portion of the same codeword derived from the first unified data set to yield a processing codeword.

A data access system, the system comprising:
- a head including a first read sensor, a second read sensor and a third read sensor,
- a means for processing data from the head, the means for processing including:
- a first combining means for generating a first unified data set based upon information received from the first read sensor and information received from the second read sensor;
- a second combining means for generating a second unified data set based upon information received from the second read sensor and information received from the third read sensor;
- and
- a merging means for assembling a first portion of a codeword derived from the first unified data set with a second portion of the same codeword derived from the first unified data set to yield a processing codeword.
