Patent ID: 8559280

Claim:
An optical disk drive, comprising: an encoder, encoding raw data received from a host to obtain encoded data; a verify unit, after the encoded data is recorded onto an optical disk, comparing the recorded data read from the optical disk with the encoded data to identify recording errors; a control unit, reserving at least one recording unit of a prior segment of the encoded data as reserved data without being recorded onto the optical disk when the prior segment of the encoded data is recorded, and recording the reserved data onto the optical disk as an initial portion of a subsequent segment of the encoded data after reading of the recorded prior segment of the recorded data is completed; a memory, controlled by the control unit, storing the encoded data, and clearing the encoded data after the encoded data is recorded onto the optical disk; and a pickup head, controlled by the control unit, recording the encoded data on the optical disk, and reading recorded data from the optical disk for the verify unit, wherein the control unit directs the encoder to pre-encode at least one recording unit of the encoded data to be stored in the memory, directs the encoder to encode a fixed amount of encoded data to be stored in the memory in each recording iteration, and drives the pickup head to record the fixed amount of the encoded data to the optical disk in each recording iteration, thus leaving at least one recording unit of the encoded data in the memory as the reserved data without being recorded onto the optical disk during each recording iteration.
