OPTICAL INFORMATION RECORDING APPARATUS AND METHOD

摘要

Recording of information by utilizing a holography to each information recording area while moving a record medium having information recording areas by means of a practical light source. For recording of information on an information recording area (7) of a record medium, an irradiated position (101) is moved so that the irradiated position (101) with information light and recording reference light may follow one information recording area (7) which moves for a predetermined period. Thus, one information recording area (7) keeps on being irradiated with information light and recording reference light, so that information is recorded on this information recording area (7) in interference patterns due to the interference of the information light with the recording reference light.
