ABSTRACT:
A video cassette recorder (VCR) record compensation apparatus that provides an optimal record environment based on the record time of the tape. This apparatus includes a record amplifier which controls the amplitude of a video signal to be recorded via a head based on the record time of the tape, to prevent the image quality from deteriorating due to magnetization characteristics of the tape. Also included is a record equalizer, which compensates the frequency characteristics of the video signal to be recorded based on the full record time of the tape.
