Depending on this speed, the recorded signal occurs transformed in frequency and magnitude as a function of the original signal in playback mode speed. For example: A recorded pause of 3 s passes the tape head at its highest speed in 111 ms, e.g. during FF mode near tape end. This time constant of 111 ms corresponds to a pause of 1.3 s at the beginning of the tape in playback mode. Thus a pause T is uniquely defined outside the interval 1.3 s < T < 3 s. Inside this interval T will be recognized as a pause or not dependent on the local point of tape, respectively the speed of tape. Times of pauses described investigated for this document are valid for tape devices with a speed of its spindle (FF, REW): respectively 12 to 27 times of the playback speed. ω r 51 1 s --- = |
