ABSTRACT:
Access to a location on a tape along a transportation path thereof is controlled by controlling a revolution velocity of a reel motor based on a distance from a current location of the tape to a preselected location thereon, and in accordance with an estimated deviation in the revolution velocity between an optimum value at which the reel motor ideally should be driven and an actual revolution velocity at which the reel motor is actually driven.
