20090168617 | OPTICAL DISK RECORDING APPARATUS AND METHOD FOR CONTROLLING OPTICAL DISK RECORDING - To provide a simple configuration capable of recording data on an optical disc reliably at high speed even if recording errors occur. Data that is normally recorded on the optical disc is erased from a storing means, and when a recording error has occurred, a predetermined range subsequent to the address at which the recording error has occurred is selected as a skip area, and this skip area is skipped to record the data stored in the storing means from a recording resume address of the optical disc. This makes it possible to avoid repetition of recording errors in the vicinity of the error-occurring location where the possibility of repeating errors is high. Data retransmission at the time of resuming recording can also be omitted to eliminate the time loss for retransmitting the data, and to reduce the storage space of the host unit necessary for storing the data to be retransmitted. | 07-02-2009 |
