ABSTRACT:
An information recording apparatus for recording at least a video signal and a digital audio signal onto an optical record medium, is provided with: a pulse signal generation device for generating a pulse signal having a pulse width corresponding to the video signal and the digital audio signal to be recorded; a first pulse width adjustment device coupled to the pulse signal generation device, for decreasing the pulse width of the pulse signal by an amount proportional to the pulse width of the pulse signal to output a firstly adjusted signal having a firstly adjusted pulse width; a second pulse width adjustment device coupled to the first pulse width adjustment device, for increasing the firstly adjusted pulse width of the firstly adjusted signal by a predetermined amount to output a secondly adjusted signal having a secondly adjusted pulse width; and a light emission device for emitting a recording light corresponding to the secondly adjusted signal onto the optical record medium to form a record pit having a pit length corresponding to the secondly adjusted pulse width of the secondly adjusted signal.
