Abstract
The present invention provides an information storage apparatus which at least records information by applying a magnetic field to a recording medium with a smaller power consumption. A default value of a recording magnetic field is set to a minimum value of the apparatus. Through a learning process, the default value of the recording magnetic field is changed to a value in the vicinity of the minimum value.
