Abstract
PURPOSE: To ensure reproduction of the steady picture with no installation of the delay means by specifying the multiple speed at the multiple speed reproduction time including the back motion and giving the reproduction scanning to the single recording track of the same azimuth at the reproduction scanning time.
CONSTITUTION: The tape running speed is set to (4n+1)-fold of the normal reproduction time when the quick motion or the back motion is reproduced. At the same time, the delay amount of the 1/(4n+1)-division output of the control signal and the reproduction variation amount to the recording track are set so as to satisfy Y=2(4n+1)X+4(n-n/|n|) in the range of [1/(4n+1)]≤X≤[2/4(n+1)] as well as to satisfy Y=2(4n+1)X-4n in the range of 0<X≤1/(4n+1), where Y is the variation amount of the scanning direction and X is the delay amount each. Thus the reproduction scanning becomes possible for the single track of the same azimuth at the reproduction scanning time.
