Abstract
PURPOSE: To enable the effective writing to a recording layer by effectively using incident radiation beam energy by providing an incident surface with an antireflection relief structure of a required shape. CONSTITUTION: A transparent substrate 5 having the incident surface 7 is provided with a laminate 9 composed of a partial reflection layer 10, an interference layer 11, the recording layer 9, an interference layer 12, a reflection layer 13, protective film 14, etc., by which the optical recording carrier is formed. Projecting bits 16, 17, etc., are written via an incident radiation beam 6 and are read. If this surface 7 is provided with the antireflection relief structure having the shape of the groove of circular or spiral shapes, the writing, etc., to the layer 8 by effectively utilizing the energy of the beam 6 are made possible. As a result, the optical recording carrier which may be enhanced in its reading and writing quality by applying the energy of the quantity necessary for writing to the recording layer.
