ABSTRACT:
A recording and/or reproducing apparatus which includes no pinch roller and no capstan and wherein the converging time to a rated speed upon starting of feeding of a tape can be reduced and the tape can be fed stably at the rated speed during recording and/or reproduction of the tape. A rotary encoder for detecting a period of rotation is disposed between a recording and/or reproducing head and a take-up side reel, and a deviation from a predetermined reference value or a feeding position of the tape is calculated from the period of rotation detected by the rotary encoder.
