摘要：<p>PURPOSE:To obtain an optimum tracking position at the time of stopping a tape by controlling the quantity of braking according to a tracking error formed based on a reproduction pilot obtained from a rotary head output at the time of feeding the tape at normal speed. CONSTITUTION:When it is expected that the tracking before the brake is applied within one frame period for performing a normal reproduction is stable, the comparison outputs C1 and C2 of comparators 31 and 32 for ATF errors at the time of the normal reproduction are sampled by a sampling pulse SP1, the length of the period when a signal FW/RV goes to 1 according to the sampling value, namely the quantity of the braking is controlled and the tape is controlled so as to stop at a noiseless still position. at least, the quantity of the braking is controlled in such a manner that the ATF error is not deviated from a dynamic range. Thereby, the state in which the ATF error is deviated from the dynamic range and noise is constantly generated can be prevented and a still reproduction can be performed at the noise still position.</p>
