    摘要： An optical information recording medium having a structure in which irregular reflection of information light and recording/reproducing light from the reflective layer of an optical information record medium is prevented, thereby reducing the noise appearing on the reproduced image. The optical information recording medium for recording information by holography comprises a transparent substrate, a recording layer where information is recorded by an interference pattern, and a filter layer formed between the transparent substrate and the recording layer and adapted to transmit a light of a first wavelength and reflect a light of a second wavelength. The filter layer of the thus structured optical information recording medium transmits a light of the first wavelength (for example, red light) and reflects a light of the second wavelength (for example, green light). As a result, two lights of different wavelengths can be separated and used for different purposes without being influenced by each other.

    摘要： [Task]It is an object of the invention to provide an optical information reproducing apparatus and an optical information storing/reproducing apparatus which utilize holography, wherein noise due to reference light is reduced than in conventional apparatuses. [Solving Means]An optical system in which arrangement is made so that at least part of a light path of reference light for reproduction is redundant with a light path of reproduction light, and a means to let through the reproduction light and shut out reflected light of the reference light for reproduction, which is reflected by a storage medium on the redundant path are provided.

    摘要： A lens retaining barrel includes a cylindrical part for radially positioning a lens and an abutment for positioning the lens in the direction of the optical axis of the lens. The cylindrical part has a multiplicity of protrusions uniformly and circumferentially spaced around the interior thereof such that a circle inscribed within the protrusions has the same diameter as the outer diameter of the lens and has its center coincident with the optical axis of the lens. The abutment extends radially inwardly a greater extent than the protrusions and has a multiplicity of seats uniformly and circumferentially spaced around the abutment for receiving the lens. The seats have tops defining an envelope extending in a direction orthogonal to the optical axis of the lens. The lens is retained in position by each protrusion of the cylindrical part and each top of the seats and is adhered to the lens retaining barrel by an adhesive. By virtue of this construction, the lens retaining barrel is free from any eccentricity or tilt of the lens, has a higher mounting accuracy, and is easy to assemble for mounting.
