ABSTRACT:
A record carrier is described having an optically readable radiation-reflecting information structure, comprising information areas arranged in information tracks, which areas are spaced from each other by intermediate areas, the information areas having oblique walls. It is demonstrated that a suitable information signal and a suitable positional error signal are obtained if the angle of inclination of the walls of the information area lies between 65.degree. and 85.degree. and the phase depth of the information areas lies between 95.degree. and 140.degree..
