摘要: A recording apparatus overwrites an input signal (s1) having pulse duration periods and spacing to a optical disk by irradiation of laser beam form marks corresponding the periods. The includes detector (10) for detecting leading edge period producing start thereupon, another (11) trailing stop pattern setting circuit (3) predetermined basic pattern, generator (12) generating from its beginning in response terminating generation signal. further (9, Ia, Ib, Ic, 4) forming modulated using full or portion produced (12). is
