    摘要: A record carrier is described in which information is recorded in an optically readable information structure comprising trackwise arranged information areas; as well as an apparatus for reading said record carrier. By arranging the adjacent information track portions on different slopes the track spacing can be reduced without increasing crosstalk.

    摘要: 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..
