A micro-magnetization analysis program, method, and apparatus which can analyze transitional change of a micro-magnetization state while one of a plurality of magnetic substances such as a recording medium and a recording head is moved in an arbitrary direction. An input unit reads an analysis object model in which merely regions of a magnetic substance fixed in a space and a magnetic substance to be moved are subjected to mesh-division into minute elements and analysis conditions. A magnetic field distribution calculating unit generates a first magnetic field equation, generates a second magnetic field equation, and solves the simultaneous equations thereof.
