Title: Optical information recording medium
Inventor: HASHIMOTO NORIO
IPC: G11B7/257
Filed: 1985-11-14
Abstract: PURPOSE:To improve the shelf stability of a recording layer and to prevent cracking in an intermediate layer by interposing the intermediate layer contg. a metallic oxide and essentially contg. silicon carbide between a substrate and the recording layer. CONSTITUTION:Laser light irradiated to the substrate 1 arrives at the recording layer 3 where the light is absorbed. The recording layer is locally heated up to the Curie point and the magnetization is annihilated. An inverse magnetic domain is formed and information is recorded when the magnetic field in the reverse direction is impressed to the annihilated part. The laser light is irradiated to the recording layer 3 and the magnetization in the direction opposite from the direction in the recording stage is impressed thereto to erase the recording. The film thickness of the intermediate layer 2 which is the film consisting of a mixture composed of SiC and Al2O3 is set at the thickness at which an antireflection function is exhibited with respect to the wavelength of the laser light in the stage of erasure so that the temp. increase of the recording layer is made effective for recording and erasure. The shelf life of the recording layer is thus improved and the cracking of the intermediate layer is prevented.

Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To further finely reproduce a video signal against all the area of contrast having the same bit rate and to reproduce a picture with the same quality at a low bit rate by transmitting and storing overhead information concerning with the range of a vector component and an index group in a macroblock. SOLUTION: At first, an input frame of a video signal encoder is digitalized, and finely divided into blocks called vector which are not superimposed spatially in pixel data. The number of blocks is different vector by vector, but in general, it is 4, 8 or 16. A series of vector is finely divided into macroblocks. A quantization step vector for each dimension is first obtained by an LVQ 13. Then, the number of quantization levels is determined, and only the step is adjusted within the present range of the macroblock. Thus obtained index and overhead information go through the Huffman or an arithmetical coding procedure, to be removed the statistical duplication of the video signal.
