FIELD: information technology.
SUBSTANCE: method of writing medium assessment is suggested. The method assesses the address reproduction error rate from the oscillation signal amplitude fluctuation value, as well as from the signal-to-noise ratio (SNR). Then, the certain range with low error rate should be set, and it should be defined whether the address reproduction error rate lies within the certain range.
EFFECT: assessment of the reproduction error rate.
