Abstract

PURPOSE: To obtain a magnetic recorder which can be adapted to any one of NTSC, PAL and SECAM systems, by fixing tape-running speeds of respective systems and by selecting the speed of a rotary drum corresponding to systems.
CONSTITUTION: In the television-signal magnetic recorder equipped with rotating video heads 1a and 1b, magnetic tape 3 is so controlled that it will run at a constant speed synchronizing with the output of a reference-signal generator with a constant frequency (capstan servo circuit). Then, the frequency of a periodic signal contained in an input television signal is discriminated and on the basis of this discrimination result, the rotation speed of rotary drum 1 which corresponds to a television signal is selected automatically, so that the rotation speed can be obtained which synchronizes with the television signal (drum servo circuit)
