ABSTRACT:
A super-resolution optical recording medium has at least a recording layer and a super resolution layer on a substrate. In the recording layer, a minimum recording mark is formed with spaces within a beam spot of a laser beam in recording. The minimum recording mark has a size of a resolution limit of a reproduction optical system or less, and can be reproduced by the reproduction optical system due to the existence of the super solution layer. The minimum recording mark in an AFM image takes the shape of a convex arc on a leading edge thereof and the shape of a concave arc on a trailing edge thereof (the AFM image is a plan view which can be observed on a surface when the light transmission layer is removed), and spaces have the similar shape to these.
