ABSTRACT:
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.
