Title: Optical information recording medium, mask for producing optical information recording medium and manufacture thereof
Inventor: YASUI TOSHIAKI
IPC: G11B7/24073
Filed: 1988-07-22
Abstract: PURPOSE:To obtain excellent recording/reproducing characteristics by forming approximately triangular pregrooves and prepits of the trapezoidal shape deeper than said pregrooves to a substrate consisting of transparent ceramics. CONSTITUTION:The substrate 1 is formed of the transparent ceramics. Signal patterns 2 are directly formed on one face of the substrate 1. The prepits 2a are formed to lambda/4n or the integer times this value when the wavelength of a radiation beam for reproduction is designated as lambda and the refractive index of the substrate 1 as (n). The pregrooves 2b corresponding to tracking signals are formed to the depth of lambda/8n or the integer multiple thereof. The prepits 2a are formed to the trapezoidal shape approximated nearly to a rectangular shape. On the other hand, the pregrooves 2b are formed to the approximately triangular sectional shape. Since the pregrooves 2b are formed to the approximately triangular sectional shape shallower than the prepits 2a, the tracking characteristics are good and troubles such as crosstalks are hardly generated.

Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To improve the image compression rate by detecting a vicinity sample point of a sample point close to a characteristic point and multiplexing image data at points except the vicinity sample point so as to reduce the generated code quantity. SOLUTION: The image coder is provided with a sample point detection means detecting a vicinity sample point close to a characteristic point from a sample point and a multiplexer means multiplexes image data at sample points except the vicinity sample points. For example, when a characteristic point (black part) is in existence in the vicinity (e.g. a range of 7×7 picture elements around a sub sample point) of a sub sample point (hatched part), the multiplexed data not including the image data at the sub sample point are outputted. Concretely image data at a sub sample point P1 in the vicinity of which a characteristic point is in existence are not included in the multiplexed data as shown in figure, for example.
