ABSTRACT:
Tape drives and methods of operating tape drives are provided. The tape drive may include: a first reel motor for rotating a first reel having a data storage tape medium wound about the first reel; a data transfer head; a second reel motor for rotating a second reel to draw the tape medium from the first reel, across the data transfer head, and onto the second reel; and at least one adaptive bearing for guiding the tape medium between the first reel and the second reel, the adaptive bearing including a roller having a first rotational resistance as the tape medium travels past the adaptive bearing at a first linear velocity and having a second rotational resistance greater than the first rotational resistance when the tape medium travels past the adaptive bearing at a second linear velocity greater than the first linear velocity. The method may include: drawing a data storage tape medium across a data transfer head between a first reel and a second reel using a first reel motor and a second reel motor; guiding the tape medium between the first reel and the second reel using at least one roller; adjusting a rotational resistance of the at least one roller to apply a first rotational resistance as the tape medium travels past the roller at a first linear velocity and to apply a second rotational resistance greater than the first rotational resistance when the tape medium travels past the roller at a second linear velocity greater than the first linear velocity.
