Abstract

PURPOSE:To facilitate recording and reproducing of various multiple information dependent upon a VTR by modulating inclination of the rise or break part of servo control pulses of the VTR. CONSTITUTION:Pulse singals recorded and reproduced in the control track for capstan servo control are modulated by control signals and are demodulated to record and reproduce control signals. Further, this modulation changes inclination of the rise or break part of pulses. That is, while noticing that only rise or break of pulses for capstan servo control is utilized for an essential purpose, other information is multiplexed and recorded. In case of transmission of control signals to a television receiver for reproducing playubg, an expensive piezo-electric tuning fork for control signal generation is needless.
