Method of controlling reel drive |
摘要 |
A method of controlling reel drive so that a magnetic tape is transported from one reel of first and second reels to the other between them at predetermined transport velocity including the steps of forming a control signal obtained by operationally determining predetermined expressions having functions of the rotational numbers of the two reels, indicating a variation in the turn numbers of the magnetic tape on the reels and of the winding radii of the reels and controlling at least one of the reels based on a comparison of the control signal with informations of rotational angular velocity of the one reel actually detected.
