Abstract

PURPOSE:To shorten the tape take-up time and at the same time to reduce the impact at the tape end part, by detecting the information on length given from the tape top and the tape end respectively and accelerating the take-up speed of the tape in a rewind mode. CONSTITUTION:A frequency generator is provided in relation to the reel drive disks 1 and 2, and the rotary information such as the number of revolutions, the revolving cycle, etc. is detected by a setecting heads 3 and 4 and supplied to an arithmetic device 5. The device 5 obtains the ratio of the speed of revolution between the take-up reel drive disk and the feed reel drive disk. The value of this ratio is stored in a storage device 6, to know the length from the tape top as well as the length from the tape end. The output signal of the device 6 is supplied to the input terminal of one side of a comparator 7 to be compared with the present ratio. The output of the comparator 7 is fed to a motor control signal producing circuit 8. Thus the speed of revolution is controlled for both disks 1 and 2.
