ABSTRACT:
A magnetic tape setting device for use in a magnetic tape recording and/or reproducing apparatus having a magnetic head, a head positioning mechanism for positioning the magnetic head to engage with a magnetic tape set in the recording and/or reproducing apparatus, a tape advancing mechanism for advancing the tape, and a controller adapted to control the head positioning mechanism and the tape advancing mechanism for various predetermined mode operations, the magnetic tape setting device being so arranged as to automatically cause, in response to a start command signal, the controller to control the head positioning mechanism and the tape advancing mechanism for firstly CUE mode operation during which the trailing edge of the recorded area of the tape being detected, secondly RVW mode operation after the lapse of a first predetermined period since the detection of the trailing edge of the recorded area, also during the second RVW mode operation the trailing edge of the recorded area of the tape being detected, and thirdly again CUE mode operation which is performed by a second predetermined short 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.
