An optical information processing device, a method for processing the optical information, and an optical information storing medium are provided to improve reproduction efficiency by projecting reference beam, signal beam, and servo control beam to the optical information storing medium synchronously. A device for processing optical information comprises optical dividers(110,130), a first servo control beam, a first optical detector(240), a second servo control beam, and a second optical detector(280). The optical divider divides lights having a predetermined wave. The first servo control beam is divided and projected to the optical information storing medium. The first optical detector detects the first servo control beam reflected form the optical information storing medium to detect focusing state of the optical information storing medium. The second control beam is projected to the optical information storing medium at different angle than the first servo control beam. The second optical detector detects the second servo control beam reflected from the optical information storing medium to measure different angle for different locations to record or reproduce the optical information of the optical information storing medium.
