摘要： An optical pickup for simultaneously reading a plurality of data tracks of an optical storage medium is provided. The optical pickup uses a diffractive element to split an illumination beam into a plurality of reading beams which are projected onto a plurality of tracks of the optical storage medium. Apparatus and methods are shown for improving the optical characteristics of the optical pickup by reducing vignetting, optical aberrations, and field curvature. These improvements are achieved by relocating the diffractive element at a greater distance from the laser source, so that a diffractive element having a larger period, and a smaller angle between diffractive orders may be used. The apparatus and methods shown also reduce the number of components and the manufacturing cost of the optical pickup.

摘要： The present invention provides an optical system having a read mode, during which multiple tracks of an optical disk are simultaneously read, and a write mode, during which data is written to at least one track of the optical disk. The multiple light beams employed during read mode may be generated by a single laser diode operated at low power used in combination with a diffractive element, multiple laser diodes, or combinations thereof.

摘要： A focus detection system for use in a multi-beam optical pickup assembly is provided that uses an optical element, either a holographic element or diffractive element, to split beams reflected off of a data-bearing surface of an optical disk into a plurality of data beams and a plurality of focus beams. The optical element also introduces astigmatism into the focus beams. The focus beams are projected onto focus detectors configured to account for overlap between adjacent focus beams to produce an accurate focus error signal.

摘要： Methods and apparatus are provided for simultaneously reading data from multiple tracks of an optical disk at a high rate. Circuitry is provided for generating a reference data clock independently of spindle motor speed and the spindle motor speed servo circuitry. Circuitry is also provided for deriving individual track data clocks from the reference data clock, while correcting for phase and frequency errors resulting from variations in the linear velocity of the tracks being read, depending upon the radial position of the tracks.

摘要： A method and system are provided for using a computer to facilitate a sales transaction between a group of buyers and at least one seller. Potential buyers may create a group organized for purchasing a product/service from one or more sellers. The computer system may output the buyers' collective request for the product/service to one or more sellers of the requested item. The sellers may respond by providing a price quotation for the requested item, often on the basis of the number of such items to be purchased by the group. The computer system notifies group members of the submitted seller quotations, in response to which some buyers may commit themselves to purchasing the item at the specified price or otherwise indicating a price at which they would be willing to commit to purchasing the item. Sellers may review the price quotations submitted by other sellers and submit competing price quotations. In a typical arrangement, an iterative process ensues in which sellers offer lower and lower prices for the requested products/services until reaching a point at which one or more buyers in the group are sufficiently comfortable with the price to commit themselves to purchasing the product/service.
