Abstract:
1. An optical disc device, for recording data having a data format of a second standard that has a higher data format efficiency than a first standard, to a first recording disc on which a PCA is provided as an area for performing test writes and a PMA is provided as an area for temporary period storage of data until a session is closed during recording, both the PCA and the PMA being located on a side closer to the center of the disc than a lead-in area in accordance with a recording disc format of the first standard, comprising: a first recording system signal processing circuit for subjecting input data to signal processing in order to generate recording data corresponding to a data format conforming to the first standard; and a second recording system signal processing circuit for subjecting input data to signal processing in order to generate recording data corresponding to a data format conforming to the second standard, wherein, when recording to the first recording disc corresponding to the first standard, it is possible to selectively use one of the first or second recording system signal processing circuits, and in the event that the recording data generated using the second recording system signal processing circuit is recorded to the first recording disc, a control processing format is switched for selectively recording the recording data generated using the second recording system signal processing circuit to the first recording disc based on a recording format conforming to one of the first or second standards, the entire PMA region is subjected to padding using special data, and disc information to be stored in the PMA according to the recording disc format of the first standard is recorded to the lead-in area.
