摘要： A method for recording information on a recording medium utilizing an interference pattern by interference between an information light modulated spatially with digital pattern information displayed on a spatial light modulator having multiple pixels and a reference light for recording. In order to provide a novel recording method capable of enhancing the recording density and the transfer rate furthermore, digital information to be recorded is represented by match/mismatch of the attributes of adjacent pixels in the spatial light modulator to produce digital pattern information.

摘要： A search method of efficiently retrieving information is provided.
A search light 21 is generated from a search condition (S1). The search light is irradiated onto a hologram 104a recorded in a hologram recording layer 104 (S2). When the search light interferes with the hologram and a reproduction light is generated, address information of the hologram from which the reproduction light is generated is identified using an address light 23 that reads the address information. The identified address light is recorded (S3). When the search light does not generate the reproduction light from the hologram, the search light is irradiated onto another hologram 104b recorded in the hologram recording layer.
