<p>A recording medium capable of reproducing information optically, which has a structure vherein the track shifted in the widthwise direction is preformatted by a signal made by removing high-frequency components from a base band signal of recorded information. A recording apparatus for forming tracks on an optical recording medium capable of reproducing information optically, which includes a deflector for deflecting a recording beam with which the tracks are formed in the widthwise direction of the track, a deflection control signal generator for generating a deflection control signal by which this deflector is controlled and a low-pass filter for removing the high-frequency components of the base band signal of the recorded information, the components being used for producing the deflection control signal in the deflection control signal generator. Thus, adverse influences on the main information recorded onto the tracks are reduced.</p> |
