Abstract

The present invention relates to an optical recording medium (10) having a layer (12), the optical properties of which are changed upon projecting a light beam with a given spot (20) size onto a surface (14) of the layer for writing data onto the optical recording medium, wherein the surface comprises regions (16) of a first type and regions (18) of a second type, the optical-properties changing-behavior of the regions of the first type and of the regions of the second type are different, and the width of the regions of the second type perpendicular to a writing direction is smaller than the spot size. The present invention farther relates to a method of manufacturing an optical recording medium.
