Title: Tracking device for optical reproducer
Inventor: GOSHIMA KENJI
IPC: G11B7/09
Filed: 1981-09-22
Abstract: PURPOSE:To correct focusing shift and track shift, by setting an inverse DC offset voltage so as to eliminate offset components equivalent to the said shifts at the start of reproduction of a disc. CONSTITUTION:An amplifier 9 outputs an EFM signal and a focus error signal. A step wave generator 143 gives a step shape pulse to a servo amplifier 102. As a result, an offset voltage component is produced in the focus error signal and the EFM signal is also fluctuated. The maximum level of this EMF signal is detected at a peak detector 18 via a BPF 11 and a detection circuit 12. In this case, a switch circuit 142 is non-conductive with the pulse of the detector 13 to interrupt the pulse. The generator 143 stores the offset voltage up to now and provides the voltage continuously to the servo amplifier 102 and the offset component corresponding to the shift of a disc 6 can be corrected with this voltage.

IPC: H04L27/22
Filed: 1990-06-08
Abstract: PURPOSE:To quicken the frequency pull-in speed of an automatic frequency control circuit by employing a frequency discriminator which inputs frequency information of an in-phase channel and an orthogonal channel, and generates and outputs a tangent frequency control signal corresponding to the result of inputting. CONSTITUTION:A signal of an in-phase channel I and a signal of an orthogonal channel Q are respectively referred to as I(t)=Acos(2piDELTAft+theta) and Q(t)=Acos(2piDELTAft+theta), where A is an amplitude, theta is a phase, and DELTAf is frequency information. When the signals I(t),Q(t) are inputted to a frequency discriminator, in which they are added, resulting that an output (d) of the frequency discriminator is expressed as d=tan(piDELTAftau), where tau is a delay time, then a tangent frequency control signal is obtained. The gradient of the output signal (d) of the frequency discriminator is expressed as sec<2>(piDELTAftau) and larger than the gradient in the frequency discrimination characteristic of a conventional control circuit. Thus, the frequency pull-in speed is much more increased.

Abstract: PURPOSE:To improve the accuracy of focus detection by correcting the position of the sampling point of the output of the second photodetector group with respect to the sampling point of the output of the first photodetector group by a coefficient of correction which can be set optionally from the external. CONSTITUTION:A value (j) which gives a minimum value to a function Q(j) is defined as j0. An image is focused in case j0=0, and the image is shited sidewise. Consequently, a defocus extent dF from the in-focus position of a photographic lens 23 to a predeterminate focal surface 33 is expressed with dF=j0 p/tantheta where theta is the angle formed between principle liminous fluxed 100A and 100B of luminous fluxed incident on photodetector groups A and B. The angle theta and the F value of the photographic lens 23 have relations tantheta=1/2F, and dF=2Fj0P is true, and the defocus extend dF is obtained. The photographic lens is moved by only this defocus extent dF to obtain the in-focus state. Thus, the position of the sampling point is corrected to a desired position to perform focus detection with a high accuracy.
