Abstract
A read retry of an MSR medium is executed while changing a setting of a reproducing magnetic field. Parameter set values of a successful read retry are stored as statistic information. When changes of the set values for defaults increase, the defaults are updated. The parameter set information of a retry success is stored as statistic information. In a new read retry, the parameter set information of a high success ratio is selected from the statistic information and the retry is executed.
