ABSTRACT:
A magnetic recording and reproducing device includes a reproducing mechanism which can be operated in a selected one of a first mode wherein information recorded on a tape is reproduced at a speed substantially equal to that at which the information was recorded, and a second mode wherein the information is reproduced at a speed different from that at which it was recorded. The reproducing mechanism includes a principal rotation head which produces an information signal in the first mode. The mechanism also includes an auxiliary rotation head which operates to detect the positional shift of the principal head relative to the tape when the first mode is selected, and reproduces the information recorded on the tape when the second mode is selected.
