ABSTRACT:
An apparatus and method for profiling the velocity of a leader block to optimize thread time in a helical scan transport uses a substantially triangular velocity profile. Local changes in acceleration and tape back tension are used to dynamically control the position of the leader block to avoid collisions with guide posts and other transport components adjacent the tape path.
