Abstract
In an optical disc recording technique for reducing cross erasure by controlling the power of a laser upon rewriting in a disc recording and reproducing method, the power of a laser is lowered to or below a reproduction power, and recording takes place at a portion where nonoverwritten and overwritten erasing portions overlap each other. Therefore, the cross erasure affecting a signal on adjacent tracks can be reduced by a thermal effect upon recording, and the cyclability on an overwriting track can be improved as well.
