ABSTRACT:
In the disclosed apparatus for recording and/or reproducing information on or from a tape-shaped record bearing medium wound around a pair of reels allowing the medium to travel in the longitudinal direction, a detector detects the rotating speed of at least one of the pair of reels; a circuit computes the amount of the tape-shaped record bearing medium on one of the reels in response to the output of the detector; a display displays the output of the circuit; and an adjusting device adjusts the degree of display precision of the display on the basis of the output of the detector.
