摘要： A video signal reproduction apparatus for reproducing a composite color video signal from a recording medium. A signal reproduced from the recording medium is divided into a frequency-modulated (FM) signal and a low-band-converted signal by filters. The FM signal is demodulated by a demodulater into a luminance signal. A first conversion circuit produces from the low-band-converted signal a chrominance signal without a phase jitter component. A second conversion circuit produces from the low-band-converted signal a high-band component of luminance signal with a same phase jitter component as that of the luminance signal obtained from the demodulator. The luminance signal from the demodulator, the high-band component of luminance signal and the chrominance signal are mixed to obtain the composite color video signal.

摘要： A magnetic tape recording/reproducing apparatus for recording video signals on a magnetic tape without providing a guard band between each two adjacent signal tracks. The apparatus comprises a first switching circuit for exchanging 2-channel component signals every nH period to obtain two combined signals each composed of the 2-channel signals which alternate every nH period, two modulators for modulating the two combined signals, a head section having two pairs of rotarty magnetic heads for recording the modulated signals on the magnetic tape so that each two adjacent blocks contain a same channel component signal and for reproducing the recorded signals from the magnetic tape, two demodulators for demodulating the reproduced signals, and a second switching circuit for exchanging the demodulated signals every nH to obtain the 2-channel component signals. With this arrangement, the recording density is remarkably increased and the cross talk interference hardly occur.

摘要： A video signal recording/reproducing apparatus has, in a recording signal processing section, a first switching circuit for exchanging 2-channel component signals at intervals of nH (n: any integer, H: horizontal scanning period) to obtain two combined signals each containing the 2-channel component signals which appear alternately at periods of nH, and a first delay circuit for delaying one of the two combined signals by nH so that the same kind of signals appear at same timings in the two combined signals. The two combined signals one of which is delayed by nH will not be interfered with each other by crosstalks therebetween which will occur in the subsequent circuits including recording and reproducing heads. A reproduced signal processing section has a second delay circuit for delaying by nH a reproduced combined signal which corresponds to the combined signal which has not been delayed in the recording signal processing section so as to recover the original timing relation between reproduced two combined signals, and a second switching circuit for exchanging the reproduced two combined signals one of which is delayed by nH by the second delay circuit at intervals of nH to obtain the original 2-channel component signals.

摘要： A video signal recording/reproducing apparatus includes a first set of rotary heads mounted on a rotary disk and a second set of rotary heads mounted on head actuators which are also mounted on the rotary disk. The apparatus has two reproduction modes. A magnetic tape in the first reproduction mode is driven at a speed equal to the speed used in a recording mode. The magnetic tape in the second reproduction mode is driven at a speed which is different from the speed used in the recording mode. The apparatus has a negative feedback loop which detects the reproduced signal level of the second set of rotary heads and drives the head actuators in order to increase the reproduced signal level of the second set of rotary heads. In the first reproduction mode, the negative feedback loop is intermittently closed. At the period of time when the negative feedback loop is open, the negative feedback loop holds the value of its output signal to that of the last time period when the negative feedback loop was closed, and, in addition, the head actuator is not driven when the feedback loop is open. At a transitional period when the apparatus switches from the first reproduction mode to the second reproduction mode, a holding signal from the negative feedback loop is supplied to the head actuator.

摘要： A multiposition controller includes a first switching element for switching on and off in accordance with a position of a movable object to be controlled and a second switching element for detecting the direction of movement of the object. The second switching element switches off when the object is positioned at one side from an initial position of the object, while it switches on when the object is positioned at the other side from the initial position of the object. Furthermore, the second switching element remains off or on when the object is positioned at the initial position. By such a simple structure, an accurate position control can be achieved.
