摘要： A holographic medium is formed of an optical waveguide including at least one core layer positioned between at least one portion of a material having a lower refractive index, a diffraction grating layer formed at a boundary between the core layer and the material of lower refractive index or in the core layer, and a storage layer outside the optical waveguide. Upon storing information in the storage layer a reference beam and an object are input into the optical waveguide and in retrieving stored information the reference beam is emitted to an end face of the core layer and transmitted through the core layer to be transformed into a diffracted beam in a diffraction grating layer that is emitted outside the core layer and transmitted through the storage layer, where the object beam is retrieved as a retrieved beam.

摘要： An optical memory medium (2) has cores (21) each constituting a planar optical waveguide and clads (22) sandwiching each core, and has a data image (203) in which data is recorded as a scattering factor and a pair of positioning marks (201, 202) which are scattering factors required for positioning at an interface between a core (21) and a clad (22) or in the core (21). A read light (103) travels while spreading in the core (21) and scatters and interferes by the data image (203), and data is reproduced from a data reproduction light (1031) generated by this scattering and interference. A pair of positioning lights (101, 102) are caused to enter the core (21) with offsets with respect to the read light (103) in opposite directions along a thickness direction of the core (21), and scatter and interfere at the pair of positioning marks (201, 202). Incidence positions of the lights emitted from a light source (11) with respect to the core (21) in a thickness direction of the core (21) are controlled based on intensities of a pair of positioning mark lights (1011, 1021) generated by this scattering and interference.
