发明名称 APPARATUS AND METHOD FOR RECORDING/REPRODUCING OPTICAL INFORMATION, AND DATA FETCHING BY REFERENCE TO OPTICAL INFORMATION RECORDING MEDIUM
摘要 <p>Provided are an optical information recording/reproducing apparatus and method capable of managing a wavelength of a light source when information is recorded/reproduced by utilizing holography, and limiting a wavelength of an interference fringe in a medium, and an optical information recording medium. For information recording/reproducing relative to an optical information recording medium by a pickup, a wavelength detector circuit detects a reference wavelength recorded in a storage area of the optical information recording medium, in accordance with the detected reference wavelength, a controller adjusts a wavelength of a light source of the pickup to have an optimum wavelength, and if a temperature detected with a temperature sensor indicates a predetermined change, readjusts the wavelength of the light source of the pickup to have an optimum wavelength.</p>
