Title: Optical recording medium
Inventor: HOSAKA TOMIJI
IPC: G11B7/246
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium with which stable tracking servo characteristics are obtd. at the time of reproducing with a CD player. SOLUTION: The surface of a substrate 1 having grooves is provided with a recording layer 2 consisting of dyestuff and a reflection layer 3. An antioxidant 5 is made to exist at the boundary of at least the substrate 1 and the recording layer 2, by which the thermal cracking of the dyestuff is suppressed and the decomposition is induced all at once near the center, where the energy of a laser beam spot is high and, therefore, the rise of a heat generation temp. is high and the decomposition of the dyestuff material by the heat absorption at the time of melting of the substrate is not suppressed. The thermal deterioration and decomposition of the substrate by the heat generated at the time of the decomposition of the dyestuff material are suppressed by the effect of the antioxidation. Recording pits are formed to a fine and uniform state without having waveform shapes.  The stable tracking servo characteristics are, therefore, obtd.

Title: Magnetic reproducing apparatus
Inventor: OTA KIYOSHI
IPC: G11B15/467
Filed: 1994-06-27
Abstract: PURPOSE:To drive an ATF circuit in an optimum state at all times by feedback controlling a digitally converted envelope value to be within a set range. CONSTITUTION:An envelope waveform of a reproduced output S1 reproduced from a recording medium 11 is detected at an envelope detection circuit 2 of an ATF circuit 14, and amplified at an amplifier circuit (GCA) 3. A microcomputer 18 digitally converts the amplified envelope waveform at an A/D converter 19 and judges at a CPU 20 whether the envelope value is within a set range. If the envelope value is smaller than the set range, a gain of the amplifier circuit 3 and an amplifier circuit (GCA) 16 amplifying and outputting the reproduced output is increased. When the envelope value is larger than the set range, the gain of the amplifier circuits 3 and 16 is lowered. Accordingly, the gain can be kept nearly constant to a signal level of the reproduced output S1 to be inputted to a phase lead/delay detection circuit 17.

IPC: H04N1/40
Filed: 1992-06-03
Abstract: PURPOSE:To eliminate quantization noise by implementing intended chattering through the addition of noise only to the vicinity where a digital signal changes stepwise. CONSTITUTION:Noise is applied to a digital signal passing through a digital filter 11 from a chattering circuit 12 and the sum is given to a D/A converter circuit 13, in which the resulting signal is converted into an analog signal and it is outputted through a low pass filter 14. That is, the digital signal is inputted to the entire circuit and the presence of low-order bits is detected. When the low-order bits are detected, whether or not the value is constant is discriminated and when the value is constant, it is discriminated the signal changes stepwise and chattering is implemented. Then, the high-order bits and the low-order bits are added and the sum is outputted. Furthermore, when the data of the low-order bits are changed during the chattering, the data are immediately outputted and the circuit restores to the initial state.
