<p>PURPOSE:To obtain a rotary magnetic head which facilitates the reproduction of high transfer rate signals and, further, facilitates the reproduction of a non- tracking system without increasing the number of coils of a rotary transformer. CONSTITUTION:Magnetic induction type heads 2 and 3 which are mainly used for recording and optical reproducing heads 4 and 5 which are exclusively used for reproduction are provided on the side of a rotary cylinder 1. The respective required numbers of the recording heads and reproducing heads which are to be provided are predetermined in accordance with a difference between the revolution of the rotary cylinder at the time of recording and the revolution at the time of reproduction to perform a non-tracking operation.</p> |
