    • A magnetic recording and reproduction apparatus corrects recording characteristics of a video signal. The apparatus comprises a luminance test signal generator for generating a frequency-modulated luminance test signal using a predetermined voltage, and a chroma test signal generator for generating a chroma test signal having a lower frequency. A recording level adjuster respectively adjusts levels of the frequency-modulated luminance test signal and the chroma test signal based on corresponding luminance and chroma recording levels. A recording unit mixes signals level-adjusted by the recording level adjuster to record a mixed test signal on a magnetic tape. A readout and preamplifying unit reads out the mixed test signal from the magnetic tape and preamplifies the read-out signal. A controller determines an optimal luminance recording level and an optimal chroma recording level to record a video signal on the magnetic tape based on the mixed test signal, and supplies the determined luminance recording level and chroma recording level to the recording level adjusting means. Accordingly, the apparatus sets optimal recording levels of the video signal capable of maximizing enhancement of the performance of the tape within a short period of time, and records the video signal, thereby improving a signal-to-noise ratio of the luminance signal and the color signal.
