| 主权项 | 1. A transport system for transporting magnetic tape, comprising: at least one roller configured to guide the magnetic tape, the at least one roller having at least three electrodes; and a controller being configured to apply a voltage to the at least three electrodes so as to produce a force of attraction between the magnetic tape and the at least three electrodes; wherein the at least one roller has at least two or three electrodes insulated from each other, the controller being configured to apply voltages of the same magnitude but opposite polarity, to the electrodes; and wherein the at least three electrodes and the controller together form an electrostatic image charge actuator or an electrostatic induction motor configured to exert a force in a direction parallel to a roller turning axis on the magnetic tape. | ||
