<p>PURPOSE: To reproduce all signals on the same tracks by one revolution of a rotary drum even in non-tracking. CONSTITUTION: This device is a reproducing device of a non-tracking system scanning a recording track with plural rotary heads. A pair of recording/ reproducing heads AR/W, BR/W arranged at intervals of nearly 180 deg. and with azimuths different from each other and first - fourth reproducing heads AP1, BP1, AP2, BP2 of double azimuth constitution so as to oppose by 180 deg. to each other in the positions separated by 90 deg. from a pair of recording/reproducing heads are attached to the rotary drum 13. A signal is recorded alternately by a pair of recording/reproducing heads, and the signals from the same azimuth tracks are reproduced by three pieces of heads of the same azimuth constitution at a signal reproducing time. By such a manner, all signals of the same tracks are reproduced by one revolution of the rotary drum.</p> |
