Abstract: In a digital servo system suitable for controlling the rotational phase of a rotating body, such as, the rotary head drum of a video tape recorder (VTR), a binary output signal is provided, as a phase error signal, based upon the phase relation between a reference signal and a command signal showing the rotational phase of the rotary head drum, and such binary output signal is used to process a motor drive signal. Further, an analog servo system is used in association with the digital servo system to provide highly accurate correction of both high and low frequency phase errors.

Abstract: In an apparatus for reproducing video or other information signals recorded in a track on a magnetic tape or other record medium; a magnetic head or transducer is moved along the track for reproducing the information signals recorded therein while a bi-morph leaf which supports the head receives an electrical drive signal for deflecting the head in a direction transverse to that along the track. A deflection signal is generated in correspondence to the deflection of the head from a rest position by a circuit which includes a strain gauge fixed on the bi-morph leaf. A control circuit for controlling the deflection of the head includes an oscillator providing a dither oscillation signal which, on application to the bi-morph leaf, causes transverse oscillation of the head about a null position, an envelope detector detecting the envelope of the reproduced output of the head, a multiplier for synchronously demodulating the detected envelope by means of the deflection signal so as to obtain a tracking error signal accurately representative of the deviation of the null position of the head from the center of the track, and an adder adding the tracking error signal to the dither oscillation signal so as to provide therefrom the electrical drive signal and by which the null position of the oscillated head is aligned with the center of the track.

Abstract: In an apparatus for reproducing video or other information signals recorded in a track on a magnetic tape or other record medium; a magnetic head or transducer is moved along the track for reproducing the information signals recorded therein while a bi-morph leaf which supports the head receives an electrical drive signal for deflecting the head in a direction transverse to that along the track. A deflection responsive signal is generated in correspondence to the deflection of the head from a rest position, for example, in response to varying the capacitance of a capacitor formed of a fixed electrode and a movable electrode on the bi-morph leaf. A control circuit for controlling the deflection of the head includes an oscillator providing a dither oscillation signal which, on application to the bi-morph leaf, causes transverse oscillation of the head about a null position, an envelope detector detecting the envelope of the reproduced output of the head, a multiplier for synchronously demodulating the detected envelope by means of the deflection responsive signal so as to obtain a tracking error signal accurately representative of the deviation of the null position of the head from the center of the track, and an adder adding the tracking error signal to the dither oscillation signal so as to provide therefrom the electrical drive signal and by which the null position of the oscillated head is aligned with the center of the track.

Abstract: A Cl2 gas plasma is generated at a site within a chamber between a substrate and a metal member. The metal member is etched with the Cl2 gas plasma to form a precursor. A nitrogen gas is excited in a manner isolated from the chamber accommodating the substrate. A metal nitride is formed upon reaction between excited nitrogen and the precursor, and formed as a film on the substrate. After film formation of the metal nitride, a metal component of the precursor is formed as a film on the metal nitride on the substrate. In this manner, a barrier metal film with excellent burial properties and a very small thickness is produced at a high speed, with diffusion of metal being suppressed and adhesion to the metal being improved.
