Abstract:
A data recording apparatus for recording data to one of a first optical disc and a second optical disc having a higher recording density than the first optical disc, the apparatus comprising:means for appending a plurality of data linking blocks to each unit of data to be continuously written to the optical disc; means for error-correction coding and interleaving of the data in the data unit having the data linking blocks appended thereto by the means for appending; means for continuously writing the data having been subjected to the error-correction coding by the means for error-correction coding to the optical disc at each unit of data having the plurality of data linking bocks appended thereto by the means for appending; and an optical disc discriminator for judging whether the data is to be written by the data writing means to the first optical disc or the second disc having a higher recording density than the first optical disc, wherein when the optical disc discriminator judges that the data is to be written by the data writing means to the first optical disc, the means for appending appends a plurality of data linking blocks, including two run-out blocks, to each unit of data to be continuously written to the first optical disc, and the error-correction coding means interleaves the data with a unit delay of four frames, and when the optical disc discriminator judges that the data is to be written by the data writing means to the second optical disc having the higher recording density than the first optical disc, the means for appending appends a plurality of data linking blocks, including three run-out blocks, to each unit of data to be continuously written to the second optical disc, and the error-correction coding means interleaves the data with a unit delay of seven frames.
