Abstract
A method of winding a predetermined length of magnetic recording tape from a large reel (on which the tape is initially wound), onto a small reel, in which the running speed of the tape is gradually increased at the beginning stage of each winding cycle to a predetermined high speed, is subsequently kept at the high speed, and is gradually slowed down near the end of the cycle, and then the tape is finally stopped to end the cycle. Simultaneously with the beginning of each winding cycle, an encoder begins to generate a pulse train, the number of pulses of which is in proportion to the number of rotations of the small reel. The number of pulses in the pulse train is counted and the tape running speed is gradually slowed down when the number of pulses counted reaches a predetermined value according to the time at which the tape running speed is to be gradually slowed down.
