Abstract
When data recording is interrupted, a location at which data have been last recorded is accurately detected and a seamless restart of the recording is achieved even if reproducing errors occur due to scratches or the like on an optical disk. A pattern data that indicates a pit pattern of data to be recorded or having been recorded is compared to a pattern data that is reproduced within a predetermined range (window) of clock cycles, and when a match is obtained, a recording restart signal is output to restart the recording operation.
