ABSTRACT:
An improved servo control device and method for a VCR that minimizes jitter caused in a reproducing mode of the VCR (reproducing VCR) when it reproduces a video signal recorded by another VCR (recording VCR). A recording characteristic of the recording VCR (such as a duty interval of horizontal synchronous signals contained in the video signal) is used along with one or more reproducing characteristics (such as speed and phase) of the reproducing VCR to control a rotation speed of the reproducing VCR's drum motor.
