FIELD: high-density optical data media. SUBSTANCE: optical medium has sequences of pits made in mentioned medium material along its record track, each pit having N optical bar heterogeneities, where N≥1; at N > 1 bar heterogeneities within each pit are parallel and periodic; in this case they form angle θ relative to electromagnetic-wave electric field vector of reading beam; angle θ, functions as elementary data source and is different for different pits. EFFECT: enhanced information capacity of optical record medium. 8 cl, 7 dwg
