    摘要: In a system for writing a plurality of information tracks between adjacent portions of a reference track on a rotatable medium, advantage is taken of the fact that laser beam dithering a cross an edge of a reference track produces signals which are analyzable to determine much more exact radial positions. A pattern of bits is written on the medium with a known spacing between bits. This may be at the time of disk manufacture or later. As these bits are being read, a clock is started along with a bit counter. At this time, a precise determination is made of the radial position at which the read bits are present. From these values, angular and/or linear velocities are computed and stored on the medium. Collected over time, this information is useful for determining aging characteristics of the drive mechanism for the medium. Also, even one-time collection of this speed information is useful for determining the speed at which data was written so that the drive speed can be accurately controlled for read operations, for example.

    摘要: A method is provided for reading an information track, or a writable disk with reference tracks, almost immediately after the information track has been written. Precise control of the positioning of the laser source which provides the parallel beams for writing and reading, is accomplished by analysis of the electrical signal produced by a reference beam reflected from an edge of a reference track on the disk/medium. Oscillatory movement of this beam across a track edge produces the desired electrical signal for precise position determination, and hence, for precise position control.

    摘要: A photodetector and a threshold detector are employed to determine from which side (left or right) of an embedded track light is being reflected from. This information is encoded in the light signal reflected from a rotatable storage medium by oscillatorily moving a laser beam back and forth across an edge of the embedded track. A waveform detector provides a signal, based on the output of the photodetector, which provides an indication of distance away from the edge of a subject track. The output of the threshold detector and waveform detector drive an up-down counter which thus associates a unique binary number with each information track.

    摘要: Methods and systems for fabrication of injection molded optical components. In one embodiment, a moldplate with cavities receives injected optical material within walls of the cavities. The cavities are designed with a geometric profile approximately corresponding to a optical profile of an optical element to be formed therein. When molten optical material is injected into the cavities of the moldplate, the injected optical material forms a meniscus due to surface tension between the optical material and the wall of the cavities. The meniscus thus provides a shape corresponding to the predetermined optical profile. The optical material is then rapidly cured with actinic radiation, and a desired optical element with high-precision dimensions is formed within the cavities of the moldplate. In some embodiments, the moldplate is spun such that the meniscus is adjusted to match the predetermined optical profile within a certain tolerance.
