PROBLEM TO BE SOLVED: To provide an optical disk recording and reproducing device which can record a signal on a disk with a laser beam emitted by an optical pickup. SOLUTION: The optical disk recording and reproducing device, which records a data signal onto a disk by reading out the data signal temporarily stored in a buffer RAM 11 and also performs recording restarting operation after recording operation interruption so that the signal is recorded successively to a signal having been recorded on the disk 1 before the recording interruption, stores the data signal stored in the buffer RAM 11 and position information data indicating the position where the recording operation was carried out into a nonvolatile memory 13 when the power supply is cut off during the recording operation.
