Title: Reproducing device for recording disk
Inventor: SAKAI MASAAKI
IPC: G11B19/28
Filed: 1981-03-03
Abstract: PURPOSE:To eliminate irregularity of rotation due to eccentricity by detecting variations of rotation of an arm tracing the spiral groove of a record disk, and by turning the record disk by increasing the detection output according to a trace from the outer circumference to the inner circumgerence. CONSTITUTION:The variation of the turning angle of a pickup arm 5, tracing the spiral recording groove of a record disk 4, for the single rotation of the record disk is detected by a detecting means 10. The detecting means 10 is constituted as a variable capacitor by fitting a metallic plate 10a as a rotor and further fitting a metallic plate 10b as a stator to a fixed member. The output of the means 10 is frequency-discriminated 12 by varying the oscillation frequency of an oscillator 11 and applied to an HPF13 and an LPF14. The output of the HPF13 is supplied to an adding circuit 16 via a variable gain amplifier 15 and the output of the LPF14, on the other hand, increases the gain of the amplifier 15 as the arm moves from the outer circumference to the inner circumference of the record disk 4. The output of a reference signal generator 17 and that of addition 16 are used for servocontrol over the speed of a motor 20, thus eliminating irregularity of rotation.
