摘要： When recording on a holographic recording medium by using a recording beam, the time required for an asking servo control to recover is reduced to increase the data transfer rate. In the holographic recording apparatus 10, a laser beam from a laser light source 16 is formed into a collimated beam having an expanded beam diameter and then is divided into an object beam and a reference beam. The divided object beam is modulated according to information to be recorded, and these object and reference beams are made incident on the reflective surface of a rotating polygon mirror 18, while maintaining collimated beam shapes and being adjacent to each other, through a condenser lens 24 having a focal point behind the reflective surface of the polygon mirror 18. The object and reference beams are made incident on the holographic recording medium 12 moving in the same direction as their scanning direction with angles different from each other so as to interfere with each other within the holographic recording medium 12.

摘要： The pitch of light beam spots on a light receiving surface of an address detector upon search of information recorded on a holographic recording medium is decreased to reduce a distance between the holographic recording medium and the address detector. In a holographic recording and reproducing apparatus 10, a reference beam having an elliptical beam shape transformed by a beam shaping optical system 30 and an object beam having an unchanged circular shape are projected onto a holographic recording medium 20 so that interference fringes are allowed to be formed only within the elliptical shape. Therefore, even when the distance of an address detector 28 from the holographic recording medium 20 is reduced, crosstalk is prevented between array-shaped two-dimensional photodetectors 28A, 28B, 28C, and so on constituting the address detector 28.

摘要： In recording of information, an information beam as S-polarization is incident on an optical information recording medium. After passing through the optical information recording medium, the information beam is reflected by reflection apparatus and passes through a polarization controller. In this process, the information beam undergoes S-polarization control and the polarization direction changes to P-polarization direction. The information beam interferes with a recording reference beam as P-polarization incident on a surface of the optical information recording medium inside the optical information recording medium to form an interference pattern. In reproduction of information, a reproduction reference beam is incident on the surface of the optical information recording medium. The reproduction reference beam is then diffracted by a refractive index grating caused by an interference pattern formed in the optical information recording medium to form a reproduction beam. The reproduction beam is emitted from the surface of the optical information recording medium and is incident on a light receiving element. The original data is then reproduced.

摘要： A holographic recording and reproduction apparatus has a spatial light modulator for converting digital information to a two-dimensional image and for intensity modulating an object beam based on the two-dimensional image. The spatial light modulator is configured to employ four or more pixels on the two-dimensional image as a unit pixel block, and allow at least two types of encoded patterns having a different number of ON pixels in the unit pixel block to be present at the same time for display of the two-dimensional image. During a reproduction operation, a two-dimensional photodetector detects the amount of light on per unit pixel block basis to determine the number of its ON pixels and then set a threshold, and thereafter an image pickup device detects the image.
