Abstract
In a magnetic recording/reproducing apparatus having a support which reciprocates between reproduce and stop positions and is biased by a spring in the direction of the reproduce position, a magnetic head which is mounted such that it contacts with a magnetic tape at the reproduce position and disengages from the magnetic tape at the stop position. The head is mounted on the support and a pinch roller is mounted where it can be depressed against a capstan at the reproduce position. The pinch roller is removed from the capstan at the stop position on the support or on a deck. The pinch roller is also biased by a spring in the direction of the capstan. The reproducing apparatus has a magnetic body actuator which mechanically actuates a mechanism which slightly moves the support from the reproduce position to the stop position side to a desired degree so that the magnetic head keeps a slight contact with the magnetic tape and disengages the pinch roller from the capstan. An electromagnetic apparatus latches and holds the magnetic body actuator by magnetic force. A mechanism extinguishes the electromagnetic force by electric signals from a non-signal zone detecting circuit which detect…
