Patent ID: 7984340

Claim:
A data recording method for recording data to a disc, comprising the steps of: recording data to a DVD and to a higher recording density disc having a recording density that is higher than the DVD: when recording data to the higher recording density disc, then: forming a data block organized as data columns and data rows, each data row comprising a plurality of bytes; for each data column in the data block, adding bytes to include an error correcting code parity; rearranging the order of bytes in each data row according plural rearranging rules to produce a rearranged data block, including rearranging a first row of data according to a first rearranging rule and rearranging at least a second row of data according to a second rearranging rule different from the first rearranging rule; modulating each of the data rows in the rearranged data block to data frames constructing a run-length limited data block; and recording the run-length limited data block to the higher recording density disc, data recorded on the higher recording density disc in the run-length limited data block.
