ABSTRACT:
An apparatus and method are disclosed for advancing a tape at a constant, high speed. Two detectors are provided for detecting values representative of the rotational periods of the reels at both low and high tape advance speeds. A calculator is included for determining particular arithmetic functions of these values. A comparator is also provided, which has a memory for storing a parameter dependent on a particular arithmetic function of values representative of low speed rotational periods of the reels. The comparator is provided for comparing the results of a particular arithmetic function of values representative of high speed rotational periods of the reels with the parameter and for outputting an error signal for adjusting the tape advance speed to maintain a constant, high speed.
