The light-beam scanning apparatus including diffraction gratings for minimizing either: a sum total of values obtained by weighting a square of an optical path length difference between an optical path of a light flux measured along a principle axis of a light beam incident on and diffracted by a first diffraction grating of a rotatable hologram, and incident on and diffracted by a second diffraction grating of a fixed plate to conduct a scanning and converging on a scanning point on an image formation surface, and an optical path of a light flux measured along a marginal ray distanced from the principal axis or an absolute value of the optical path difference thereof; or a sum total of values obtained by weighting a square of a sum obtained by adding an amount of displacement of a light-beam convergent on a scanning point on the image formation surface, to an amount of displacement of the same light. The displacement measured with respect to the principal axis of a phase recorded on the diffraction grating when the light flux is incident on the fixed plate or by weighting an absolute value of the sum.

摘要： An optimized design method of a holographic optical element by calculating a correction coefficient so that an evaluating amount of a reconstructed light reconstructed by the holographic optical element can be minimized, the correction coefficient determining an aspheric term included in a phase transfer function, the phase transfer function representing a shape of an interference fringe recorded on the holographic optical element. According to the method, the wavefront aberration is expressed via a linear function of the correction coefficient by positioning a main axis point on a characteristic evaluating surface onto which the reconstructed light is projected, so that a wavefront aberration of the reconstructed light can be minimized. Then, the correction coefficient is calculated based on the linear function so that the evaluating amount can minimized.

摘要： A method for constructing a hologram on a transparent disk which includes two steps. First, irradiating a reference wave light beam having a diverging spherical wave front from a first point light source located at a predetermined distance on a center axis of the transparent disk. Second, irradiating an object wave light beam having a diverging spherical wave front from a second point light source located at a predetermined distance on a normal line away from a predetermined distance from the center axis. The result is interference between the reference wave light beam irradiated by the first point light source and the object wave light beam irradiated by the second point light source on the transparent disk and the formation of interference fringes having an extreme value of a spatial frequency as a hologram in one embodiment, a reconstruction beam is irradiated to the position, or in the vicinity of the extreme value.

摘要： A control information decoding section (102) decodes sets of control information contained in a stream. Further, a random access information analyzing section (101) carries out analysis of locations of random access points of media items contained in the stream, on the basis of the sets of control information. Still further, a management information generating section (103) generates management information for managing a plurality of random access points contained in the stream, on the basis of decoded versions of the sets of control information, which has been obtained by the control information decoding section (102), and the locations of the random access points obtained by the analysis performed by the random access information analyzing section (101). Then, the management information thus generated and the stream are recorded onto a storage medium (104). This makes it possible to quickly start playback in performing random-access playback of a stream into which control signals are inserted at regular intervals.

摘要： A first optical system irradiates a target with a detecting wave and making the detecting wave that is transmitted through the target incident upon the electrooptical crystal. A second optical system slants a pulse plane of a probe wave relative to a pulse plane of the detecting wave and making the probe wave incident upon the electrooptical crystal. A camera detects the probe wave passing through the electrooptical crystal. The first or second optical system includes a compensating component which partitions a beam cross section of the detecting wave or the probe wave into unit areas. The optical component makes different an optical path length of a beam passing each unit area and compensates a phase shifting between the pulse plane of the detecting wave and the pulse plane of the probe wave at positions in a crossing direction of a surface of the electrooptical crystal and the virtual plane.

摘要： A magnetic recording medium used for the thermally assisted magnetic recording system which fires a laser beam at a magnetic recording medium to partially heat the medium and applies a magnetic field from the outside to the part heated to lower the coercivity for recording. The magnetic recording medium is configured by a glass substrate on which a heat radiation layer, heat retention layer, intermediate layer, and recording layer are stacked. Further, the heat retention layer is configured by a member having an effective refractive index lower than the effective refractive index of the recording layer and having an temperature diffusion coefficient determined by the specific heat, density, and heat conductivity rate higher than glass and lower than metal. The material with a high temperature diffusion coefficient is used lowered in temperature diffusion coefficient using a porous structure or granular structure.

摘要： A sub-sampling portion (101) sub-samples images of data corresponding to the left and right viewpoints. A joining method selector (104) selects the joining method that minimizes the discontinuity at the boundary in the joined image when the sub-sampled images of data are joined. A joining portion (102) joins the plurality of images data, based on the selected joining method. An encoder (103) encodes the joined image data, and a joining method encoder (105) encodes the information of the joining method. A multiplexer (106) multiplexes these pieces of coded data. In this way, the continuity of the joined image is improved, whereby the coding efficiency is enhanced.
