    Abstract: Systems and method relating generally to data processing, and more particularly to systems and methods for segmenting a data set and recovering the segmented data set. In one particular example, a method is disclosed that includes: querying an input data set for an actual sync mark; forcing a proxy sync mark where the actual sync mark is not found in the input data set; applying data processing to the input data set to yield a processed output; correlating a potion of the processed output with a corresponding portion of the input data set to yield a true sync location; calculating a difference between the true sync location and the location of the forced sync mark to yield an offset; re-forcing the proxy sync mark based upon the offset; and re-applying the data processing to the input data set aligned using the re-forced proxy sync mark to yield a re-processed output.

    Abstract: A storage system and method for interleaving a plurality of logical sectors in the storage system is disclosed. The method includes: dividing each logical sector into a predetermined number of slices; sequentially indexing the logical sectors, wherein each logical sector is identified by a logical sector index; sequentially indexing the predetermined number of slices in each logical sector, wherein each slice of the predetermined number of slices is identified by a slice index within each logical sector; and interleaving the logical sectors according to a slice interleaving process. The interleaving step further includes: a) identifying a first indexed slice of a first indexed logical sector as an initial slice; and b) identifying a subsequent slice by advancing the slice index to a subsequent index in the slice index sequence and advancing the logical sector index to a subsequent index in the logical sector index sequence.
