摘要： A holographic recording medium 10 includes: a recording layer 12; two substrates 14 and 16 sandwiching the same; and a photosensitive protective layer 18 covering these recording layer 12 and substrates 14 and 16 entirely. The recording layer 12 is set so that its photosensitivity corresponding to a recording wavelength falls in the vicinity of the recording wavelength from shorter wavelengths to longer wavelengths. The photosensitive protective layer 18 is set so that its light transmittance corresponding to the recording wavelength falls in the vicinity of the recording wavelength from longer wavelengths to shorter wavelengths. This improves damage of the recording layer from ambient exposure without a drop in recording sensitivity.

摘要： A holographic recording method and a holographic recording apparatus which can provide a shortened time for recording and an improved data rate during recording even when the recording material has a low photosensitivity or the light source has a low power. This is achieved by, before a minimum exposure time for forming a reproducible hologram is reached, completing an interference exposure using signal light and reference light to form an incomplete hologram; performing an independent exposure for irradiating the incomplete hologram with the reference light after the interference exposure to thereby produce diffracted light; and recording information by means of interference between the reference light and the diffracted light.

摘要： A holographic multiplex recording method is provided in which remaining dynamic range in each recording area is made more uniform upon holographic multiplex recording. In this holographic recording method, a first-stage recording spot row RX1 is formed by arranging recording spots RS in an X-axis direction without overlapping, and then a second-stage recording spot row RX2 formed of the recording spots RS without overlapping in the X-axis direction is recorded in a position for shift multiplex recording in a Y-axis direction. This is repeated to form a Y-axis direction first multiplex recording spot matrix TYX1. In this case, recording is performed to all recordable regions without shift multiplex recording in the X-axis direction. Subsequently, a Y-axis direction second multiplex recording spot matrix TYX2 is formed in a position shift-multiplexed in the X-axis direction with respect to the first-stage recording spot row RX1 initially recorded. The shift multiplex recording in the X-axis direction is performed in a similar manner up to a Y-axis direction last multiplex recording spot matrix TYXn to thereby complete the recording.

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.
摘要翻译：在搜索记录在全息记录介质上的信息时，地址检测器的光接收表面上的光束点的间距减小以减小全息记录介质和地址检测器之间的距离。在全息记录和再现装置10中，具有由光束整形光学系统30变换的椭圆形波束形状的参考光束和具有不变的圆形的物体光束投影到全息记录介质20上，使得干涉条纹被允许为仅在椭圆形状内形成。因此，即使减少地址检测器28与全息记录介质20的距离，也可以防止构成地址检测器28的阵列状的二维光电检测器28A，28B，28C等之间的串扰。

摘要： It is an object of the present invention to provide an information recording method for recording information in a data rewritable type optical recording medium having a plurality of information recording layers whereby a sufficiently high erasing efficiency can be ensured when data recorded in any one of the information recording layers are directly overwritten. In the information recording method according to the present invention, information is recorded in an optical recording medium 10 having at least a stacked L0 layer 20 and L1 layer 30 by projecting a laser beam thereonto via a light incidence plane 13a. In the case where information is to be recorded in the optical recording medium 10, information is recorded in the L0 layer 20 using an off-pulse recording format and information is recorded in the L1 layer 30 using an on-pulse recording format. As a result, even in the case of directly overwriting data recorded in either of the L0 layer 20 or the L1 layer 30, a sufficiently high erasing efficiency can be ensured.
