IPC: G11B21/10
Filed: 1982-07-31
Abstract: PURPOSE:To stabilize a tracking servo, by providing a means which changes the point of intersection of gain of a tracking servo means in accordance with the speed of revolution of a recording carrier, and suppressing the variation of the gain of the tracking servo against the basic frequency of off-center. CONSTITUTION:The G4 in the diagram represents the transfer function of an equalizer 41 and G5 that of a DC amplifier 42 whose gain is K and characteristic is flat. A number of revolution detect signal of disks is inputted into a terminal 40. The gain of the DC amplifier 42 becomes larger when the speed of revolution becomes higher and its point of intersection of gain becomes f4, f5, and f6 when the rotary frequency is f1, f2, and f3, respectively. Since the gain of the equalizer 41 becomes k1, k2, and k3 when the rotary frequency is f1, f2, and f3, respectively, and each of them has the point of intersection of gain of f4, f5, and f6, the open loop gain becomes (K1-K4), (K2-K5), and (K3-K6), respectively, and they are constituted so that they become almost fixed values. Thus, incidence of malfunctions is suppressed to the minimum, because the light beam correctly follows the track and the point of intersection of gain is suppressed to a necessary minimum even when a fault in the track gives a disturbance to the servo system.

Filed: 1981-08-28
Abstract: PURPOSE:To improve the controllability and the accuracy of a generator and to suppress the operating frequency of the controller by providing an insensitive band circuit at the input side of a proportional arithmetic unit. CONSTITUTION:When a deviation VE occurs between the output V0 of a generator 8 and the set value VS, an integator 21 outputs as an output EE1 the integrated value of the deviation VE, and a proportional operational amplifier 20 receives the difference of the insensitive band of an insensitive band circuit 3 when the deviation VE exceeds the band and outputs an output VEP. An adder 22 adds the output VEP and VE1 and outputs the sum to a controller 4. When the deviation EE becomes small and enters to the insensitve band, the output VEP of the amplifier 20 is eliminated, but the deviation VE is integrated by an integrator 21 to generate the output VE1 while even small amount of the deviation VE remains. Accordingly, the deviation VE is gradually approached to zero.
