REPRODUCING DEVICE AND REPRODUCING METHOD

PROBLEM TO BE SOLVED: To provide a reproducing device capable of obtaining the stable reproduction property by improving such a state that the proper equalizer control is impossible due to the malfunction in the interchangeable reproduction, the running of a tape, or the like. SOLUTION: A reproduction signal outputted from a variable equalizer means 2 making the amplitude property and phase property of the amplified reproduction signal variable which is amplified by a head amplifier means 1, is quantized by an A/D conversion means 3, and the error of the reproduction signal subjected to digital conversion by the A/D conversion means 3 is corrected by a digital signal processing means 4, and the error unconverted to the original digital signal by this error correction is detected by an error detecting means 7. Then, the error value is integrated by an error calculating means 10 based on an output signal of the error detecting means 7, and also the amplitude of the reproduction signal amplified by the head amplifier means 1 is detected by an amplitude detecting means 5, and the error calculating area is changed by a variable means 6 of error calculating area in accordance with the detected amplitude of the reproduction signal, then the variable equalizer means 2 is controlled in accordance with the error value in the error calculating area.
