摘要： Luminance and chrominance signals, which are interleaved with respective synchronization signals, are recorded through the use of two video transducer heads alternately in skewed separate tracks of a recording tape. Upon reproduction, the timing signals are separated from the luminance and chrominance signals and compared in phase between them to detect the phase difference between the luminance and chrominance signals. A variable delay line is provided to introduce a variable delay interval as a function of the detected phase difference to the one of the signals which is advanced in phase relative to the other. The time axis deviation of the video signal from a standard phase is also detected by a comparison between the time base, or horizontal sync pulse, and a reference time base to introduce a delay time to both the luminance and chrominance signals.

摘要： A portable video tape recorder for broadcasting applications comprises a pair of video heads mounted diametrically opposite to each other on the circumference of a rotary cylinder. High and low frequency carriers are modulated by frequency modulators with I and Q signals, respectively, and frequency division multiplexed for application to the video heads. The frequency values of the carriers are selected so that third-order distortion noise caused by the hysteresis characteristics of the video heads and the magnetic tape may fall within a frequency range differing from the frequencies of the modulated carriers by an amount greater than the bandwidth of the I and Q signals which are demodulated by frequency demodulators to prevent the occurrence of beat interference in the frequency band of the reproduced video signal.

摘要： In a video tape recorder, luminance and chrominance signals are recorded respectively by first and second transducer heads along separate tracks skewed to the direction of tape motion. The transducer heads are rotated during particular modes such as slow-motion or still picture reproduction, in a tape-head speed relationship different from the normal tape-head speed relationship, causing the transducer heads to traverse several tracks. A switching circuit is coupled to the transducer heads to selectively connect the outputs of the heads to an output circuit in response to a point of transition of amplitude of the output signal from the second head to cancel unwanted signal components detected by the heads during traversal across the tracks.

摘要： A recording apparatus of the present invention includes selective guard adding means for predicting, at the time of editing, positions of adjacency of new tracks to previously recorded tracks obtained at the time of completion of new track recording, and adds, at the time of editing, guards to locations where disturbance due to residue of erasing of the same azimuth might occur in order to remove or reduce the disturbance due to residue of erasing of the same azimuth caused at the editing point. When performing reproduction from a recording medium whereon tracks recorded by heads of at least two kinds of azimuth angles are disposed alternately and a plurality of tracks are handled as one recording unit and recorded, a reproducing apparatus of the present invention is so configured that the center of each of heads located at both ends of reproducing heads may be shifted to the inside as compared with each corresponding recording track. When disturbance due to the residue of erasing of the same azimuth occurs at the editing point, therefore, more signals of tracks to be originally reproduced can be reproduced, resulting in a greater resistance to disturbance of the same azimuth.

摘要： A recording and reproducing apparatus includes two recording heads, two re-recording heads and one erasing head. The two recording heads are utilized to record directly adjacent recording tracks having no guard band therebetween. The adjacent recording tracks constitute a recording track set, and a plurality of such recording track sets are recorded on a recording medium such that a guard band is provided between adjacent ones of the recording track sets. The erasing head has an erasing width which is greater than a corresponding width of each recording track set, and it utilized to erase an already recording track set which was recorded using the two recording heads. The re-recording heads each have a recording width which is greater than that of each of the two recording heads, and are utilized to record newly recorded track sets in place of the already recorded track sets erased by the erasing head.

摘要： The present invention relates to a magnetic recording and reproducing system of a rotary head type in which a video signal of a predetermined unit and audio signals corresponding to the video signal of the predetermined unit are sequentially recorded on and reproduced from a magnetic tape as a single record locus which is slanted with respect to the longitudinal direction of the magnetic tape by rotary heads. Two pairs of rotary heads are used as the rotary heads and the video signal and the audio signals to be processed are recorded by one pair of preceding heads among those two pairs of heads, while upon reproduction, the audio signals are reproduced by one pair of preceding heads and the video signal is reproduced by one pair of delayed heads. The reproduced audio signals and the video signal are processed to thereby obtain the video and audio signals in which the timings are coincident.
