Title:
追記型光ディスクの記録方法
Document Type and Number:
Japanese Patent JP4174967
Kind Code:
B2
Abstract:
When an error has occurred during the recording of an optical disk, the track recording system is changed from a variable-length packet write system to a fixed-length packet write system employing an arbitrary length (step S2). A check is performed to determine whether before the error occurred the number of blocks used for recording was equal to or greater than 300, which is the minimum block length for one track (step S4). When at least 300 blocks have not been used for recording, by using as a recording unit a fixed-length packet having the arbitrary length, the dummy data are continuously recorded until the used block count reaches 300 (steps S5 to S7). Thus, when an error occurs during the recording of dummy data (Yes at step S6), one fixed-length packet is added (step S8) and the recording of dummy data is continued.
