Abstract
PURPOSE: To improve the precision of a tape run system and also to obtain a high- precision control signal for wow and flutter correction by generating fixed pulses from a control signal reproduced from a recording track of a pilot signal synchronizing with a vertical synchronizing signal.
CONSTITUTION: Pilot signal (d) of frequency nfv phase-synchronizing with vertical synchronizing signal (a) of frequency fv of a TV signal recorded by rotary head 11 is generated and inverted 9 at cycles (m) times vertical synchronizing signal (a) to obtain signal (e), which is recorded 11 as a control signal on a length-directional recording track of a magnetic tape. In playback mode, pulse signal (j) of frequency fv/m and a continuous-phase pulse signal without polarity inversion are generated 20 from reproduced control signal (e) reproduced 11 from the recording track. Consequently, the precision of a tape run system can be made high and a high- precision control signal for wow and flutter correction can be obtained.
