A stepper-motor-driven capstan is connected to a split band whose two portions loop around two idlers disposed on a displacement member and in line with the displacement and are doubled back to be affixed to another stepping device, such as multi-position armature devices or another step-motor-driven capstan. This arrangement permits interspersing of steps in order to reduce the actuator step length for a given stepping angle of the motor or motors, for increasing, for example, track density on a disk cooperating with a transducer on the displacement member.
