Abstract

PURPOSE:To fulfill excellently the recording formation of a recording track and the tracing of the recording track by making it possible to obtain a signal for tracking control in recording and reproduction on the basis of a reproduced signal in recording operation. CONSTITUTION:Rotary drum 1 is provided with magnetic head sets 20a and 20b, composed of magnetic head Hr for information signal recording and reproduction and magnetic head Hp for tracking control signal reproduction, and tracking control driving mechanisms 18a and 18b and pairs of set 20a and mechanism 18a, and set 20b and mechanism 18b constitute magnetic head assemblies respectively. Then, heads 20a and 20b differ in azimuth each other. Now, when head Hr records or read information signals on or from recording tracks (t1), (t2) ..., head Hp compares signals, read out from two adjoining recording tracks, with a reference signal and driving mechanisms 18a and 18b are so controlled that a difference between comparison results will be zero.
