摘要： An object of the present invention is to make it possible to record information on an optical information recording medium in the form of three dimensional interference patterns so that the information is erasable in part.The optical information recording medium (1) has an information recording layer (3) made of a magneto-optic recording material. A pick-up (11) of an optical information recording/reproducing apparatus generates information light by spatially modulating laser light emitted from a light source unit (20) with a spatial light modulator (22), and generates recording-specific reference light spatially modulated in phase by spatially modulating the phase of the laser light emitted from the light source (20) with a phase-spatial light modulator (16). The information recording layer (3) of the optical information recording medium (1) is irradiated with the information light and the recording-specific reference light. An electromagnetic coil (30) applies a magnetic field to the information recording layer (3). A three-dimensional distribution pattern of magnetization corresponding to the interference pattern resulting from the information light and the recording-specific reference light is formed in the information recording layer (3).

摘要： It is an object of the invention to allow the use of a practical light source to record information in each information recording area of a recording medium having a plurality of information recording areas through the use of holography while moving the recording medium.When recording information in the information recording areas (7) of the recording medium, the irradiating position (101) of information light and recording-specific reference light is moved such that the irradiating position (101) follows a single moving information recording area (7) for a predetermined period. Consequently, the single information recording area (7) keeps being irradiated with the information light and the recording-specific reference light for the predetermined period. Information is thus recorded in this information recording area (7) in the form of an interference pattern as a result of interference between the information light and the recording-specific reference light.
