Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for skewed orthogonal coding techniques. In one aspect, a method includes receiving a block of data comprising a plurality of data chunks. One or more rows of word code chunks are generated using a first linear error-correcting code in systematic form and the data chunks. For each of m rows of the data chunks, one or more split row code chunks are generated using the data chunks of the row, wherein the split row code chunks are generated so that a linear combination of m split row code chunks from different rows forms a first word code chunk of a first codeword including the data chunks and the word code chunks. The rows of data chunks and the split row code chunks and the word code chunks are stored.
