ABSTRACT:
A tape recording apparatus comprises a first mechanism capable of varying, between a maximum and a minimum length, a tape travel path extending between a recording and reproducing head and a tape take-up roll. A second mechanism controls the first mechanism so that the length of the tape travel path becomes the maximum length at the time of ordinary recording and at the time of editing. The length of the tape travel path becomes the minimum length at the time of a pause mode prior to the editing recording. A third mechanism pulls back the tape by a length equal to the difference between the maximum and minimum lengths, at the time of the pause mode, of the tape path between the tape roll on the tape supply side and the recording and reproducing head. A fourth mechanism detects when the first mechanism reaches substantially maximum tape length at the time of the editing recording mode, and causes the start of editing recording by the recording and reproducing head.
