发明名称 OPTICAL RECORDING MEDIUM AND INFORMATION RECORDING APPARATUS.
摘要 The recording medium for reproducing information optically, has a structure where 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 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.
