ABSTRACT:
A recording or reproducing apparatus according to the present invention includes a loading member movable between an unloading position at which a tape is accommodated into a cassette and a loading position at which the tape is pulled out from the cassette and wrapped around a rotary head drum to enable recording or reproduction, a detecting circuit for causing the rotary head drum to start rotating when the loading member is located at a predetermined position between the unloading and loading positions and the tape is wrapped around the rotary head drum by a predetermined angle, and detecting a rotational speed which the rotary head drum reaches within a predetermined time, and a control circuit for driving the loading member to the loading position if it is determined that the rotary head drum is not wet with dew condensation from the rotational speed of the rotary head drum detected by the detecting circuit, and if it is determined that the rotary head drum is wet with dew condensation, driving the loading member to the unloading position.
