Systems and Methods for Sample Averaging in Data Processing

A method for processing a data set, the method comprising:

• performing a first read of a user data set to yield a first instance of the user data set;
• performing a second read of a user data set to yield a second instance of the user data set;
• combining at least a first segment of the first instance of the user data set with a first segment of the second instance of the user data set to yield a first combined data segment;
• providing a second combined data set that is a combination of at least a second segment of the first instance of the user data set, and wherein the combination excludes a second segment of the second instance of the user data set;
• and
• providing at least the first combined data set and the second combined data set as an aggregate data set.

A data storage device, the storage device comprising:

• a storage medium maintaining information;
• a sensor device disposed in relation to the storage medium and operable to sense the information and to provide a corresponding analog signal;
• an analog to digital converter circuit operable to convert a derivative of the analog signal to a series of digital samples;
• an equalizer circuit operable to perform an equalization on the series of digital samples to yield a first equalized output corresponding to a first read of the information, a second equalized output corresponding to a second read of the information, and a third equalized output corresponding to a third read of the information;
• and
• a combining circuit operable to:
• combine at least a first segment of the first equalized output with a first segment of the second equalized output to yield a first combined data segment;
• provide a second combined data set that includes a combination of one or more second segments from the second equalized output and the third equalized output, and wherein the second combined data set excludes a second segment of the first equalized output;
• and
• provide an aggregate data set including at least the first combined data set and the second combined data set.
