ABSTRACT:
In a magnetic recording control device, a plurality of test signals of different frequencies are recorded on and reproduced from a magnetic recording medium, and the reproduction levels of the test signals are detected. From the detection results, the frequency characteristics and electro-magnetic conversion characteristics of the magnetic recording medium are judged. A frequency correction in accordance with the judged frequency characteristics, and a record level correction in accordance with the judged electro-magnetic conversion characteristics are conducted on a video signal to be recorded.
