Abstract:
1. A method comprising: receiving a stream of codewords from a hard disk controller, wherein each codeword of the stream of codewords comprises a plurality of symbols; receiving a write gate signal, the write gate signal configured to request a read/write channel to write at least a first part of the stream of codewords to a media; receiving a symbol count signal, wherein the symbol count signal indicates a number of symbols in the first part of the stream of codewords; encoding, using a low-density parity-check coding algorithm, at least a first codeword from the stream of codewords; based at least in part on the encoding of at least the first codeword, transmitting a write data ready signal; and responsive at least in part to the transmitting of the write data ready signal, receiving the write gate signal.
