摘要： A still picture reproducing system for a magnetic recording and reproducing apparatus is disclosed. The system sends one frame in order to shift a reproduction mode from ordinary reproduction to reproduction of a still picture by use of so-called "fine slow", sends one more frame if a noise is detected on a picture at this time, and stops if no noise is detected.

摘要： In a slow-motion device of a helical scan type video tape recorder, detection is effected to detect a noise in a reproduced signal which is caused when the magnetic tape is fed such that the magnetic heads which have reproduced a preceding still image at a track transfer to the succeeding track and thereafter the magnetic heads scan the succeeding track, and the position of the magnetic tape is controlled by a tape control system so that the noise is confined within a position at a noise bar due to the noise is prevented from being displayed on the reproduction screen.

摘要： A magnetic recording and reproducing apparatus having a construction in which a digital signal including index signals recorded on a magnetic tape is reproduced and rotary magnetic heads are movable. The digital signal is reproduced by digital signal reproducing means including the rotary magnetic heads. A particular index signal among the index signals is detected by index signal detecting means. Further, the timing for reproducing the particular index signal is detected by timing detecting means. The rotary magnetic heads are moved and deviated in the direction of the rotary shaft of the rotary cylinder by rotary magnetic head position deviating means. Tape speed detecting means compares a reproduction clock with a reference clock and outputs a tape speed signal. First rotary magnetic head position deviation control means forms a control input for the rotary magnetic head position deviating means on the basis of the tape speed signal. Second rotary magnetic head position deviation control means forms the control input for the rotary magnetic head position deviating means on the basis of an output signal of the timing detecting means.

摘要： A memory controlling apparatus for a magnetic recording and reproducing apparatus which records and reproduces a field image signal in each read or write cycle performed by a video head for reproducing the image signal from a magnetic tape, and by a video head position detector for detecting the position of the video head. A reference circuit obtains a signal defining a reference timing which is independent of the position of the video head and which is also used to determine the phase of the video head. A memory is provided having storage sufficient to store the field image signal, and a controller is provided for controlling the operation of reading and writing the image signal from and into the memory. The controller is synchronized with a signal of the video head position detector when storing the image signal into the memory and when reading out the image stored in the memory, the controller and the head position detector are synchronized with the reference timing so as to enable production of a slow-motion image signal free from fluctuations caused by feeding of the magnetic tape.
