るブレーキ制御装置。[Claim for Utility Model Registration] Tape recording and playback in which a reel wound with tape is attached to a reel disk, the reel disk is driven by a drive motor during tape running, and the rail disk is braked by a main brake when the tape running speed is decelerated. In the apparatus, when the tape running speed is decelerated, the rotation speed of the reel disk is detected, and when the rotation speed of the reel disk exceeds a set value, a current is applied to the drive motor that generates a torque in a direction opposite to the rotation direction of the reel disk. Brake control characterized in that energization is applied to perform reverse phase braking, and in a range in which the rotational speed of the reel disk is smaller than a set value, energization to the drive motor is stopped and braking is performed by the main brake. Device.
