摘要： A focus error detecting apparatus is improved by splitting the light detector into three portions, with a first portion located between second and third portions and being elongated. The elongation prevents an out-of-focus condition where the detection light spot is elliptically elongated in the elongation direction from being falsely detected as the focused condition.

摘要： An optical device with an improved efficiency in the transmission of light through the device is disclosed. The device having an optical element in a block shape which is made up of a first plane on which incident light is presented at a predetermined incidence angle. The incident light is transmitted through the first plane and is reflected off of another plane which is oriented at a predetermined angle with respect to a plane perpendicular to the first plane. The reflected light is next totally transmitted through an exit plane situated parallel to the first plane. The incidence angle is predetermined so that the angle at which the light is finally transmitted with respect to the exit plane is a polarization angle satisfying Brewster's rule. Therefore, at the exit plane, the light is totally transmitted and thus none of the light is reflected, resulting in a greatly improved degree of efficiency in the transmission of light through the device.

摘要： An optical pickup for astigmatic focusing on an optical disk. A planar beam splitter reflects light from a source through an objective lens to the recording track of the disk. The light reflected from the disk is transmitted through the beam splitter. The beam splitter is inclined to the optical axis so that astigmatism is produced on transmission. A cylindrical lens is placed along the path of the transmitted light and is oriented so that the combined astigmatism is aligned with a quadruple element detector.

摘要： A first thermal buffer layer and a second thermal buffer layer are arranged between a recording medium and an actuator structure. The heat conductivity of the first thermal buffer layer is set low and the heat conductivity of the second thermal buffer layer is set high. Most of the heat generated from a coil wiring of the actuator structure is blocked by the first thermal buffer layer, and heat leaked from the first thermal buffer layer is diffused by the second thermal buffer layer. Temperature distribution on the recording medium is made uniform, and thus, a configuration wherein the recording medium and the actuator structure are placed one over another can be provided, information reading accuracy or information recording stability can be improved and the sizes of an information storage device can be reduced.
