ABSTRACT:
A magnetic recording device records an input signal on a magnetic medium. Either when the magnetic medium is first inserted in the device, or just before recording of the input signal is to begin, the device determines whether a previously-recorded signal is present on the medium. If no previously-recorded signal is present, a test signal is recorded and reproduced, and the reproduced level of at least one test frequency is measured. Thereafter, during recording of the input signal, the input signal is processed according to the measured level so as to produce a record signal optimally matched to the characteristics of the medium.
