Optical disc recording/reproducing apparatus having automatic protection of previously recorded data

摘要

Record position information is recorded in a lead-in area disposed on an innermost peripheral side of a disc. When a record commanding means for commanding a start of recording operation is operated while a reproducing operation of a reproducing means is being stopped, a recording head is moved to a blank area on the disc which is detected on the basis of the record position information recorded in the lead-in area and input data is recorded in the blank area. When the record commanding means for commanding a start of recording operation is operated while the reproducing operation of the reproducing means is being paused, the recording head is moved to a position of a signal which has been outputted when the recording operation has been paused and the input data is recorded from this position.
