Abstract:
An information storage apparatus which carries out a recording to record information on a recording medium magneto-optically by applying a recording magnetic field to the recording medium, comprising:a magnetic field generating unit that applies a magnetic field to the recording medium; a magnetic control unit that specifies a control value for controlling a magnitude of the magnetic field generated by the magnetic field generating unit to a value within a control range of recording magnetic field of the magnetic field generating unit; a storage unit that stores an initial value of the control value, said initial value being a minimum value of the control value within the control range, the minimum value being a value obtained in a nominal state; a detection unit that detects a write error during the recording; and an updating unit that updates the initial value to a new control value within the control range depending on the write error detected by said detection unit.
