  • Patent number: 4405955
    Abstract: In an apparatus for reproducing video signals recorded in successive parallel tracks extending at an angle to the lengthwise direction of a tape and wherein two main reproducing heads having different azimuth angles with respect to each other are arranged to be diametrically opposed and alternately reproduce the video signals from the tracks when the tape is transported lengthwise at a standard speed, and an auxiliary reproducing head having the same azimuth angle as one of the main reproducing heads is circumferentially displaced by (n+0.

  • Patent number: 4399473
    Abstract: In an apparatus which reproduces video signals using rotating heads to scan oblique tracks formed on a tape, the tape is intermittently moved and stopped by a tape capstan motor which is driven by a motor drive pulse. The motor drive pulse is generated at predetermined time intervals corresponding to a predetermined number of tracks for slow-motion reproduction of the recorded video signals. Deviations in the amount of tape intermittently advanced, as measured by a predetermined number of tracks, is avoided by varying the pulse-width or amplitude of the motor drive pulse.

  • Patent number: 4396954
    Abstract: In an apparatus which reproduces video signals from oblique tracks successively formed on a tape, there are provided at least two main rotary heads having different azimuth angles with respect to each other an auxiliary rotary head having the same azimuth angle as that of one of the main rotary heads and which is disposed to substantially scan the same track as that scanned by the one of the main rotary heads.
