摘要： A highly efficient lighting system, a scrolling unit, and a projection system adopting the highly efficient lighting system and the scrolling unit are provided. The scrolling unit has at least one lens cell. From the viewpoint of light incident upon the at least one lens cell, the rotation of the at least one lens cell is converted into a rectilinear motion of a lens array, such that incident light is scrolled. The projection system includes a light source, an optical splitter, at least one scrolling unit, and a light valve. The optical splitter splits light emitted from the light source according to wavelenght. The at least one scrolling unit has at least one lens cell. The lens cell has an incident side and an emitting side and divides incident light into light beams. The rotation of the lens cell causes a rectilinear motion of the light beams, thereby scrolling incident light. The light emitted from the light source is separated into color beams by the optical splitter and the scrolling unit, and the color beams are focused on the light valve. The light valve processes incident light according to an input image signal in order to form a color image.

摘要： An optical disc for an optical near-field recording having a surface with a textured structure formed with a plurality of bumps and craters, and a method of manufacturing the optical disc. An optical flying head has a slider which contacts the bumps when in a parking zone (non-moving state) so that a contact area between the optical disc and the optical flying head is reduced. Accordingly, a stiction force is reduced, so that the wear and damage to the optical disc having the textured structure and to the optical flying head are minimized.

摘要： An optical data storage system writes or reads information with respect to an optical storage medium using an optical pickup including a solid immersion optical system or a solid immersion lens for generating a near-field and emitting a light beam. The optical storage medium includes a recording layer which is formed on a surface of an optical transmissive layer opposite to another surface of the optical transmissive layer which opposes the solid immersion optical system or solid immersion lens. The thickness of the optical transmissive layer is larger than one wavelength of the light beam. The interval between the surfaces of the solid immersion lens or solid immersion optical system and the optical transmissive layer is smaller than one wavelength of the light beam. Thus, the light beam reflected from the inside of an air gap and the inside of the optical storage medium between the air gap and the recording layer does not function as noise with respect to the light reflected from the recording layer. Also, since the thickness of a protective layer or a substrate which is an external surface of the optical storage medium can be thickened, information can be written or read with respect to the optical storage medium even when the optical storage medium has dust and/or damage.

The compatible optical pickup includes a first optical source for emitting a first light beam having a predetermined wavelength; a second optical source for emitting a second light beam having a long wavelength relative to the first light beam; an optical path changing element for changing the traveling path of an incident light beam; an objective lens for condensing the first and second light beams onto optical discs having different thicknesses, respectively; an optical diffraction element having a first region which directly transmits the first and second light beams incident thereto, and a second region bounding the first region, which directly transmits the incident first light beam and diffractingly transmits the second light beam toward an optical axis; and a photodetector for detecting an information signal and an error signal from the first and second light beam which have been reflected by the optical discs and passed through the optical path changing element. Also, the optical diffraction element is a stepped planar lens in which one or more stepped pattern periods each having a plurality of annular gratings are arranged in the second region, wherein the depths of the gratings become smaller moving away from the optical axis, and the maximum depth thereof is a predetermined value.

摘要： An optical disc can increase an information storage capacity by reducing the track width of the optical disc. An optical pickup for a narrow track optical disc includes an optical shielding portion having a desired light intensity distribution with respect to a target track and the tracks adjacent to the target track on the optical disc. The optical shielding portion is disposed on the optical path between the light source and the optical disc and shields part of the light beam proceeding toward the optical disc, to provide a light intensity distribution such that only the beam spot focused on the target track is used to detect information stored in the target track. Thus, the beam spot focused on the target track of the optical disc has track crosstalk having a magnitude by which information can be read from the target track. The optical pickup can provide an excellent performance even in the case that the optical pickup is adapted in a high-definition DVD to be commercialized in the future.

摘要： An optical disc includes a substrate having micro-embossments, in which flat portions referred to as lands, and track guides, referred to as hills, and which protrude from the surfaces of the flat portions are formed. A reflective layer is formed on the substrate, a dielectric layer is formed on the reflective layer, a recording layer is formed on the dielectric layer, and a protective layer is formed on the recording layer. Thus, the lands and hills on the substrate of the optical disc enable disc fabrication to more easily facilitate manufacturing of the optical disc. Accordingly, tracks of the disc can be narrowed, to thereby enhance a recording density of the optical disc.
