Title: Optical disk
Inventor: SHIMAZAKI KATSUSUKE
IPC: G11B7/24097
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To enable high-speed rotation even for a magnetic clamp method free from occurrence of retardation by making a ratio between the area for which a hub for the magnetic clamp ('the hub') transmits a rotary force of the spindle to a substrate and the area of projection of the substrate not less than a specific value. SOLUTION: The hub 3 is made of a material that can be attracted by a magnet, and is attached to a substrate 1 in a state separated from it. The hub 3 is attracted to the magnet 4 fixed to a spindle 2. This attractive force is transmitted to the substrate 1, which is attracted to the disk supporting part of the spindle 2. The relation between the area B in which the hub 3 imparts a rotary force of the spindle to the substrate 1 and the area A of projection of the substrate 1 is set to be B/A>=0.02. For example, the projection area of the substrate is 112 cm2, and the area in which the hub 3 imparts the rotary force of the spindle to the substrate is 5.50 cm2.

Filed: 1988-12-22
Abstract: PURPOSE:To reduce sampling loss by mounting a delay device for delaying a digital signal, a memory device outputting a signal on every other sample holding circuit and a comparator comparing digital signals to output a signal having a larger value among them. CONSTITUTION:The analogue input signal 1 being the single pulse of a receiving video signal is inputted to a sample holding device 5 to output an analogue signal 6. This signal 6 is converted to a digital signal having frequency twice sampling frequency by an A/D converter 7 and a delay device 9 to which the digital signal 8 corresponding to the signal 6 delays the signal by one sampling point to store the same in a memory device 10. This delayed signal 8 and the digital signal 8 from the converter 7 are compared on every other one by a comparator 11 and one having a larger value is outputted from the comparator 11. As mentioned above, in the case of the same signal velocity, data quantity becomes almost equal to that obtained when A/D conversion is performed at twice sampling frequency and, therefore, sampling loss can be reduced.

Filed: 1987-12-23
Abstract: PURPOSE:To obtain a desired frequency characteristic through current adjustment only and without adjustment by a coil or capacitor, and to reduce cost in integrating the circuit by providing a band-pass filter and current sources, etc., to adjust the cut-off frequency and Q of said filter. CONSTITUTION:A band-pass filter 2 inputted a signal reproduced by a head from an input terminal 1 receives current from first and second current sources I1, I2 so that the mutual conductance of their respective internal amplifiers are varied, hence the cut-off frequency and the Q can be freely set from the external.
