Abstract:
1. A method for determining the position of a tape-like medium which can be moved to and fro along its longitudinal axis, wherein a detector generates first signals which correspond to the transport of the tape-like medium over a defined distance, and wherein a second signal indicates a transport direction, and wherein a third signal indicates the transport of the tape-like medium over a multiple of the defined distance, and wherein the position is determined using multiples of the defined distance, wherein the method comprises the steps of: establishing whether the transport direction is constant and defined during a defined period of time or over a defined distance, and generating a fourth signal which indicates a constant and defined transport direction; applying the incoming third signal as a counting signal to a counter when the transport direction has been constant for a defined period of time or a defined distance, the fourth signal determining whether the counter is incremented or decremented.
