Abstract: PURPOSE:To obtain an optical disc having stable cycle characteristics and excellent recording and erasing characteristics by forming a recording layer composed of a material, in which nitrogen is contained in the mixed body of GeTe, Sb2Te3 and Sb, onto a substrate. CONSTITUTION:A first protective layer 2 consisting of ZnS-SiO2 having excellent heat resistance is formed onto a transparent substrate 1 on the disc of an optical recording medium, and film thickness is brought to approximately 150nm. A recording layer 3 is made up of a thin-film, in which nitrogen is mixed with GeTe, Sb2Te3 and Sb, and a second protective layer 4 is composed of the same material as the first protective layer 2, and film thickness is brought to approximately 20nm.

The recording layer 3, in which nitrogen is mixed with GeTe, Sb2Te3 and Sb, is shaped onto the substrate 1, thus elevating a crystallizing transition temperature, then improving weather resistance. A phenomenon, in which a recording layer material is moved along a guide groove with the repetition of recording and erasing, is inhibited, thus enhancing the repetition characteristics of recording and erasing. The protective layer 4 between the recording layer 3 and the reflecting layer 5 is thinned, and quenching constitution is formed, thus allowing a change into a uniform amorphous state, then improving recording and erasing characteristics.

Abstract: PURPOSE:To improve the quality of a reproduced image by correcting the frequency of a picture element clock with respect to the variance in light beam scanning time of every plane of a polygon mirror and the position of the picture element clock with respect to the variance in scanning time in a scanning surface respectively. CONSTITUTION:A frequency value generation unit 6 is constituted of a memory, a counter circuit and a gate circuit and stores the frequency value of the picture element clock in proportion to the light beam scanning time of every plane of the polygon mirror 4 from a terminal T1 and the deviation value of light beam velocity in the scanning surface corresponding to every plane of the polygon mirror 4 from the terminal T2. And it sets a value obtained by sequentially multiplying the stored frequency value of the picture element clock by the deviation value of the light beam velocity in the scanning surface in a synthesizer 7. The synthesizer 7 outputs the picture element clocks PCK whose phases are continuous from a terminal T3 based on the set value from the frequency value generation unit 6. Since the variance in the scanning time of the light beam of every plane of the polygon mirror 4 and the scanning time in the scanning surface thereof can be corrected, the reproduced image is not deteriorated.

Title: Method and circuit for out of synchronism detection, and method and circuit for recovery
Inventor: TANI HIDEKI
IPC: H04L7/08
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to provide out of synchronism detection with low cost, more compact and few amount of hardware by detecting the out of synchronism in a digital signal processor on the basis of a relation in a time width direction between a masking and an interruption signal. SOLUTION: A digital signal processor(DSP) 10 is equipped with a masking function of an interruption(INT) signal and reads out a program specified by the INT signal from a memory part 24 and executes it in mask release. When an input of a trigger of the INT signal is faster than a predicted time, the trigger is not received by the mask at a CPU part 22, since it is before the mask release and the number of trigger of the INT signal received by the CPU part 22 becomes smaller than that of the normal time. Thus, the trigger of the INT signal is in condition in which it is not received when the CPU part 22 waits for reception. By detecting this condition, out of synchronism can be detected.
