Abstract
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.
