A tape drive comprising two motors at least a first of which is an open loop position-controlled motor arranged to provide a controllable torque, two tape spool supports on which spools of tape may be mounted, each spool being drivable by a respective motor, and a controller for controlling the energization of the motors such that the tape may be transported in at least one direction between spools mounted on the spool supports. The controller is arranged to provide a control signal to the first motor to set the tape tension. |
