Apparatus and method providing a mirror averaging function to generate a mirror signal from optical data on an optical disc

In the context of mirror modulation (56, 90, 104) extraction during track seek or jump modes of an optical disc reading device (12), such as a DVD ROM, a mirror averaged level (i.e. the dc level (52) of the RF envelope (34)) is held so that the mirror modulation (90) is seen as a swing below a set mirror rebias level (86) at an output of a mirror amplifier (72), as shown in FIG. 3. With the holding of the dc level (52) by a ground-referred capacitor (302) during seek operation of the device (12), a first input (nin) to the mirror amplifier varies with the mirror modulation, whereas a second input (pin) to the mirror amplifier (72) does not vary.

During on-track operation, the first input (nin) and the second input (pin) are essentially equal and so the RFRP ...

Method for writing and reading data on a multi-layer recordable interferometric optical disc and method for fabricating such

A recordable compact disc comprises a 0.6 millimeter clear plastic or glass substrate on which is grown a thin-film image layer having several distinct recording planes. Each recording plane is separated from the next by a clear plastic layer. Each recording plane includes an organic dye layer in combination with another clear layer that has a different index of refraction. Different color dyes are used for each recording plane. A method for storing and reading data to and from a multilayer recordable compact disc with different color dye layers uses high powered color lasers to write each recording plane and low powered monochromatic reading lasers that are sensitive to the constructive and destructive light interference effects caused by micron variations in the clear plastic layers in each recording plane. The micron variations used for each recording plane are unique and chosen along with the monochromatic reading laser colors to have minimal crosstalk between recording-plane data channels.
