发明名称 APPARATUS AND METHOD TO STORE AND RETRIEVE INFORMATION USING AN OPTICAL HOLOGRAPHIC DATA STORAGE MEDIUM
摘要 A method using an optical holographic data storage medium and an optical holographic data storage drive, comprising removeably disposing the optical holographic data storage medium in the optical holographic data storage drive, and determining whether to write information to the holographic data storage layer, and/or whether to read information from the holographic data storage layer, and/or whether to write information to the optical data storage layer, and/or whether to read information from the optical data storage layer. The optical holographic data storage medium comprises a holographic data storage layer and an optical data storage layer. The optical holographic data storage drive comprises a reflective spatial light modulator, a first lasing device, a first optical detector for detecting first laser light, a second lasing device, and a second optical detector for detecting second laser light.
