Title: Optical disk device
Inventor: WATANABE HITOSHI
IPC: G11B7/085
Filed: 1988-09-27
Abstract: PURPOSE:To omit an additional bit and to accurately execute access operation by detecting a data bit recorded on a sample servo type optical disk. CONSTITUTION:Data bits are recorded in respective data areas of the optical disk and reflected light from the optical disk is detected by a photodetector 1. The reflected light is modulated at its intensity by a data bit every time when an optical spot crosses each track and modulated at its intensity by a servo bit every time when the optical spot crosses a servo area As, so that an output signal A from the photodetector 1 is also modulated at its level by these bits. The output signal A of the photodetector 1 is supplied to a signal separating/processing circuit 2 and separated into a signal based upon the data bit and a signal based upon the servo bit and a track crossing signal SCR and a tracking error signal Str are formed respectively from these signals. Consequently, the moving direction of the optical spot can be detected without using an additional bit and access can be executed by the sample servo type optical disk.

Filed: 1983-12-21
Abstract: PURPOSE:To make a sharp polychromatic display with the high utilization efficiency of outer circumferential light by providing three kinds of selective reflecting filter which differ in reflection and transmission wavelengths alternately corresponding to liquid crystal display elements in light diffusion mode. CONSTITUTION:Incident outer circumferential light 9 is separated into transmitted light and reflected light through selective reflecting filters 7R, 7G, 7B. When the liquid crystal 1 of three liquid crystal display elements 8 constituting one picture element 8 is all in a diffusion state, red, green, and blue of the transmitted light are diffused and reflected 3 and cyan, magenta, and yellow of the reflected light are diffused by the liquid crystal in the diffusion state to see light white. When two liquid crystals are in the diffusion state, white is seen in the diffusion state and light transmitted through the selective reflecting filters 7R, 7G and 7B is seen in the transparent state, so light red, green, or blue is seen all the time. Further, when one liquid crystal display element 6 is put in the diffusion state, cyan, magenta, or yellow is seen sharply. The composite has high peak wavelength because of the selective reflecting filters and is extremely light.
