Title: Optical disc
Inventor: YAMANAKA YUTAKA
IPC: G11B7/24085
Filed: 1984-09-20
Abstract: PURPOSE:To reduce the luminous amount loss by specifying the relation between the distance between track centers and the track width to a prescribed numeral. CONSTITUTION:In detecting the position of a track, the incident light from a condenser lens 1 forms a spot on a recording layer 3 through a base 2. In assuming the slope of a differential output before and after the track center as the track detection sensitivity, when the inter-track distance P is <=2mu where 2mu is the beam spot diameter to be irradiated, the sensitivity is as shown in figure (a) with respect to the track width W, and the detection sensitivity is maximum at W=P/2. However, the total reflecting luminous amount from the recording medium has a minimum value W0 as shown in figure (b) and its value is nearly 0.5mu. When the track width W exceeds the point W0 as shown in figure (b), the reflected luminous amount is increased, it is better to use the disc in the condition of W>=P/2 in matching with the curve of the track detection sensitivity shown in figure (a).

Filed: 1983-10-24
Abstract: PURPOSE:To easily change electrical specifications or designs by providing a circuit for controlling input level within a semiconductor device and changing such control with bonding. CONSTITUTION:A signal to be input to the PAD7 is input to the gate of enhance transistor TR8. The PAD13 is an exclusive PAD for control an input level. First, PAD13 is bonded to the earth line. Thereby, the enhance TR12 becomes OFF.

Thereby, a gain in the side of driver becomes large and a gain constant ratio of driver element becomes large and a high level input voltage is lowered. As a result, design change can be realized easily.

Abstract: PURPOSE:To elevate stability of control, and control accuracy, by counting the frequency by which the physical quantity to be controlled is deviated from a blind sector, and varying a range of the blind sector in accordance with its frequency. CONSTITUTION:When the physical quantity to be controlled is detected by a detecting circuit 19, its detection voltage VX is supplied to comparators 25, 27 having a blind sector of a range between voltages VS1, VS2, respectively. An integration circuit 33 for receiving outputs of both these comparators outputs voltage being proportion to frequency by which the physical quantity has been deviated from the blind sector. Subsequently, the output of the integration circuit 33 is supplied to comparators 39, 41, respectively, and when it exceeds the upper limit value of the frequency decided in advance, a servomotor M rotates forward, a resistance value of a resistance R2 increases, and width of the blind sector expands. As a result, stability of control is elevated. Also, when said output becomes less than the lower limit frequency, the motor rotates backward, the width of the blind sector is narrowed, and accuracy of control is elevated. In this way, stability of control, and control accuracy can be elevated.
