動制御装置。 A tape player in which a pair of reel stands for driving tape reels are each driven by separate motors, and a magnetic tape pulled out from the tape reel is wound around a rotating head device,
A detector that detects the rotation speed of each reel stand, and a calculator that calculates the rotation speed of the take-up reel stand to keep the tape running speed constant based on the reel rotation speed detected by this detector. A reel motor servo circuit is provided for controlling the reel motor that drives the take-up reel stand based on the calculation result of the calculation unit and the ATF signal reproduced by the rotary head device. A tape drive control device for a tape player, characterized in that:
