Abstract: In an optical head device using a float type slide, and an information processing device, influences due to dust is reduced to prevent degradation of recording and reproducing performance. An optical head device has a slider (28) adapted to float up to the surface by an air current accompanying the rotation of a disk-like recording medium, and of the surfaces of the slider, the one which is opposed to the disk-like recording medium is formed with parallel rails (28A, 28B) along the direction of the air current. A rail (29) is formed intermediate between the two rails and beam light focused by an objective lens is allowed to permeate the rail (29) made of transparent material. It is possible to make optical influence hardly producible even if dust particles enter between the slider and the disk-like recording medium.

Abstract: Stereoscopic display with high definition compared with in the past may be easily realized. A lenticular lens 2 is disposed such that a longitudinal direction of each cylindrical lens 2A is parallel to an axis in a vertical direction Y of a two-dimensional display section 1. In addition, a plurality of beams corresponding to a plurality of view angles are radiated into a space by means of surface segmentation at a time, and a relative positional relationship between each cylindrical lens 2A and each pixel of the two-dimensional display section 1 is periodically changed, so that a radiation direction of display image light from one pixel through each cylindrical lens 2A is periodically displaced. Images corresponding to one frame of a three-dimensional video image are time-divisionally displayed for each pixel of the two-dimensional display section 1, and a timing of time division display of the two-dimensional display section 1 and a timing to change the relative positional relationship by displacement means are controlled to be synchronized with each other. Thus, stereoscopic display using a combination of a surface segmentation method and a time division method is performed, and consequently stereoscopic display with high definition compared with in the past is realized.

Abstract: A plurality of first electrodes are disposed on one of opposite surfaces of a nonlinear optical material substrate which is divided into single domains. Each of the first electrodes is made of an electric conductor having a width which is equal to or smaller than half the width of a designed local inverted-polarization domain. A second electrode is positioned on the other of the opposite surfaces in confronting relation to the first electrodes. A voltage is applied between the first and second electrodes thereby to produce local inverted-polarization domains in the nonlinear optical material substrate.
