ABSTRACT:
This invention provides a magnetic recording and reproduction apparatus that automatically cleans the head of a rotating head cylinder sufficiently. Prior to a power-off operation at step #9, based on a detection signal from a rotary encoder for detecting a rotational position of a main cam gear at step #7a, the main cam gear is inversely rotated until it reaches a position at which a cleaner head contacts the head, and is subsequently rotated forward to move tape withdrawal posts to a loading completion position. Power is turned off at step #9. Thus, automatic cleaning is provided not only when a tape cassette is inserted and ejected but also when the power is turned off. Therefore, compared to the prior art, this invention increases the opportunities of automatic cleaning to reduce the contamination of the head of the rotating head cylinder, thereby realizing excellent recording and reproduction.
