ABSTRACT:
A magnetic tape setting device for use in a magnetic tape recording and/or reproducing apparatus having a magnetic head for recording and/or reproducing, a tape advancing mechanism for advancing the magnetic tape under FF, RVW and PLAY modes, a controller adapted to control the mechanical elements thereof for the FF, RVW and PLAY mode operations to the end of the tape, and a start command signal generator for producing a start command signal when actuated, the magnetic tape setting apparatus being so arranged as to automatically cause, in response to the start command signal, the controller to induce firstly the FF mode operation, secondly RVW mode operation after the completion of the initial FF mode operation, during the second RVW mode operation the trailing edge of the recorded area of the tape being detected, and thirdly again the FF mode operation which is performed by a predetermined period after the detection of the trailing edge of the recorded area of the tape, whereby the magnetic head is automatically positioned at the leading edge of a non-recorded area of the tape i.e. a position suitable for the initiation of recording.
