摘要： A near field optical recording medium having a header area in which at least an addressing signal or a timing signal is recorded by means of a concave/convex pattern with laser light using a flying optical head. When a concave/convex portion of the concave/convex pattern is to be detected, either an effect due to a change in returning light caused by distance wherein the reflectance is changed or an effect due to a change in returning light caused by a diffraction effect is sufficiently larger, or a combination of such effects (changes by distance effect and changes by diffraction effect) are not weakened by each other, so that header information recorded by the concave/convex pattern can correctly be reproduced even in a super-high density recording medium using near field light.
