Quick Reverse Operation With Photo Sensor
A newly developedphoto sensoris usedto detectthe
point where the direction of tape transport is reversed.
This systemmakes it possibleto perform
transport reversal in about 0.9 seconds. S incetape
transport isvirtually uninterrupted, quick reverse is
ideal for continuous side A-side B playback and
recording aswell asendless playback for background
music.
