ABSTRACT:
A drawing pulse generating unit of an optical disk recording apparatus judges a bit stream of main data contained in a bit stream signal of frame-formatted data, and generates pulse signals DOTX1and DOTX2based upon the judgment, and then, outputs the generated pulse signals DOTX1and DOTX2to the gate circuit. In a time period during which a signal level of the pulse signal DOTX1is an “H” level, the gate circuit supplies a bit stream signal of the frame-formatted data to a laser driver. In a time period during which a signal level of the pulse signal DOTX1is an “L” level, the gate circuit supplies a bit stream signal indicative of an erase level to the laser driver. The laser driver controls an optical pickup so that a laser light having strength indicative of the bit stream signal is irradiated.
