Abstract
The invention provides a method for data recording of an optical disk drive. First, raw data is encoded to obtain a plurality of recording units of encoded data to be stored in a memory. The encoded data stored in the memory is then recorded to an optical disk. A predetermined number of recording units of the encoded data is then reserved in the memory as reserved data without being recorded onto the optical disk. The recorded data read from the optical disk is then compared to the corresponding encoded data stored in the memory to verify correctness of the recorded data. The reserved data is then recorded to the optical disk after correctness verification of the recorded data is completed. Finally, the aforementioned steps are repeated until there is no more raw data left as a source for encoding.
