    摘要： An apparatus for controlling recording and reproduction in a video cassette tape recorder capable of, in a recording mode, separating specific data for speed-varied reproduction from compressed digital video signals, recording them on designated tracks, recording position information of the designated tracks on a control track by an index head or recording position information of recording position-synchronized blocks at the starting portions of the designated tracks recorded with the specific data, and in a speed-varied reproduction mode, controlling a capstan servo speed so as to maintain the travel of a magnetic tape at a normal speed and periodically or non-periodically accelerate or decelerate it where specific data for varied-speed have been recorded periodically or non-periodically on predetermined portions of tracks, thereby making heads travel repeatedly at the normal speed and the high speed and thereby detect continuously the specific tracks for varied-speed. A repeatability of reproduced video at a varied speed is obtained without any deterioration in picture quality, because of recording of specific data for speed-varied reproduction and continuous detection of the specific data in the speed-varied reproduction.

    摘要： The rotary head type helical scanning magnetic tape recording and reproducing apparatus is provided with an auxiliary recording head (5a,6a,5b,6b) for recording pilot signals adjacent to a main head (3a,4a,3b,4b) for recording a signal to be recorded, and an auxiliary reproducing head (la,2a,1b,2b) for reproducing the recording pilot signals. The pilot signals recorded to an antecedent track are reproduced by the auxiliary reproducing head (1a,2a,1b,2b) at the time of recording to the next track. A tracking control of the main (3a,4a,3b,4b) head at the time of next track recording is effected according to the reproduced pilot signals.

    摘要： A magnetic recording and reproducing device according to the present invention operates with the steps of moving a magnetic tape having having a plurality of tracks per frame and a plurality of CTL signals recorded thereon, keeping count of the pulses of an FG signal corresponding to the rotation of a capstan motor by FG counting means, resetting the count of the FG pulses by the CTL signal reproduced by a fixed magnetic head, detecting the track number by the CTL counting means reset by a frame reference signal, controlling, at the start, the start timing on the basis of the tape stop position detected by the FG pulse counting means and CTL counting means and the reference frame signal from the reference frame signal generating means, said device preventing the thinning of tracks at the editing point in after-break recording and the disturbance of images immediately after the start, not requiring a special circuit or complicated software-wise processing, providing a stabilized slow-reproduced image. Further, in a magnetic recording and reproducing device for intermittent recording, there is no danger of causing thinning to recorded tracks; a reproduced image of high quality can be obtained.
