ABSTRACT:
An automatic calibration method for a read system in which data read by a head from a recording medium is demodulated using a partial response method which includes the steps of: storing at least one of a parameter relating to a bias current fed to the head and parameters necessary for data demodulation in the read system, for a plurality of operating conditions; and automatically calibrating the at least one parameter to a preset value suitable for an operating condition.
