Abstract
A tension servo apparatus includes a brake member which may apply a braking force to a reel system. The brake member is coupled to a tension arm which is displaced in response to a tape tension and may slide on the outer periphery of said reel system in accordance with the displacement of the tension arm or the rotation of the reel system.
