    摘要: The present invention aims to provide an optical recording medium that is provided with a recording layer for recording information by holography, has an uncomplicated laminate structure, is capable of performing recording and reproducing control such as tracking control and is capable of high-density multiple recording, as well as an optical recording method, an optical recording apparatus and an optical reproducing method. To this end, the present invention provides an optical recording medium which is a transmission medium for recording information based on a holographic principle using an information beam and a reference beam and performing tracking control using a servo beam, the medium including at least a first substrate, a recording layer, a filter layer that selectively reflects the servo beam, and a second substrate being disposed in this order as viewed from the light irradiation side of the information beam and the reference beam.
