The method of the present invention includes the steps of rotating a molecule having a predetermined structure by applying a first alternating current electromagnetic field to the molecule, wherein the first alternating current electromagnetic field is produced by an electromagnetic field generation means that is set to a predetermined phase, controlling a rotational phase of the molecule by applying a second electromagnetic field to the rotated molecule by an information recording means, detecting a signal using a signal detection means in accordance with a rotation of the molecule having the rotational phase which has been controlled, and outputting a shift between the phase of the first alternating current electromagnetic field and a phase of the detection signal from the signal detection means as information by an information reading means.
