摘要： The optical information recording and reproducing apparatus includes a light source for emitting a light beam, an objective lens for converging the light beam emitted from the light source to an information recording medium, and a light detector for detecting the light beam reflected from the information recording medium. The information bits are recorded into a recording member of the information recording medium in a three-dimensional arrangement by using a change in optical constant of the recording member. Furthermore, a thickness of the recording member is larger than a wavelength of the light beam and the information bits are sequentially recorded into the recording member in a three-dimensional arrangement in such an order that a converging light beam from the objective lens does not pass through information bits that have already been recorded.

摘要： A first diffractive optical element pattern with a pattern pitch that is no greater than a wavelength of incident light is formed on a first main surface of substrate such as a glass plate. Second diffractive optical element patterns are formed at positions that are respectively incident to positive first-order diffracted light and negative first-order diffracted light produced by the first diffractive optical element pattern. Negative first-order diffracted light produced by each second diffractive optical element pattern is incident upon a boundary face of the substrate at an angle that is smaller than the critical angle, and so exits the substrate.

摘要： A recording and/or reproduction apparatus, for an information medium including a substrate having concave and convex portions and a plurality of recording layers, includes a light source for emitting a light beam; an optical system for diffracting the light beam emitted by the light source so as to output a first diffracted light beam and a plurality of second diffracted light beams; and a driving section for driving the optical system. The optical system outputs the first diffracted light beam and the second diffracted light beams, such that when one of the second diffracted light beams is converged to and reflected by one of the concave and convex portions, the first diffracted light beam is converged to one of the recording layers. The driving section drives the optical system, such that the one of the second diffracted light beams is converged to the one of the concave and convex portions.

摘要： An optical head for reproducing optical recording medium (6) has reflection optical means, such as, a reflection type astigmatic optical Fresnel lens (7A, 7B) or reflection type light-beam dividing (into at least two beams) Fresnel lens (13), grating (18) or prism (19), on or above a surface of a beam splitter (4), so that reflect return light from the optical recording medium (6) travels in the beam splitter 4 to photo-detector means (8, 15) having at least two divided parts (8A, 8B, 8C, 8D or 15A, 15B, 15C, 15D); thereby size of the optical head is reduced by setting the optical path from the reflection optical means to the photo-detector inside the beam splitter (4).
