Abstract
The present disclosure describes aspects of codeword interleaving over magnetic media surfaces. In some aspects, segments of a codeword are spread or interleaved across multiple surfaces of magnetic storage media. Data for one or more codewords may be received by a read/write channel and, for each codeword, a respective index is selected, received, or generated. The index may indicate which sector partitions of the multiple surfaces that segments of one of the codewords are to be written. The data of the codewords can be segmented and then arranged in an interleaver based on the respective index to which the codeword corresponds. The codeword segments are written from the interleaver to sectors of the multiple surfaces of the magnetic media. By so doing, codewords may be spread across multiple surfaces, such that a loss of a portion of a segment track does not prevent readback and decoding of the codewords.
