ABSTRACT:
The invention is a constrained pivot compound radius tape post guide. The post is mounted on an axle which allows it to pivot when the tape changes direction. The pivoting action serves to peel away all tape which has been in stationary contact with the post, thereby reducing startup stiction. Above a certain rotation angle the post is prevented from further rotation either by a fixed stop or by torque exerted on the post by the tape which is under tension.
