PORTEUR D'INFORMATION PRESENTANT UNE STRUCTURE D'INFORMATION LISIBLE PAR VOIE OPTIQUE

摘要

A record carrier is disclosed in which information is recorded in an optically readable information structure of track-wise arranged information areas which alternate with intermediate areas. Adjacent information track portions are situated at different, parallel planes spaced from each other by a predetermined distance such as to reduce crosstalk from neighboring tracks thereby permitting the information density to be substantially increased.
