ABSTRACT:
In a rotary head type reproducing apparatus, such as a digital audio tape recorder (DAT), a display changeover operation, a key scanning operation or a sensor scanning operation is inhibited during the periods T.sub.PB-A, T.sub.PB-B when a rotary head is in contact with a magnetic tape for reproducing signals, and the display changeover operation is performed during time periods T.sub.DS1 to T.sub.DS4 outside of these periods T.sub.PB-A, T.sub.PB-B, while the scanning operations are performed during a time period T.sub.SC. An error rate may be improved because noises due to display changeover or scanning may be eliminated during the time the magnetic head is contacted with the magnetic tape for signal reproduction. The result is that shielding or the like may be eliminated and the display section of switches may be mounted in proximity to the rotary head to reduce the size of weight of the apparatus.
