摘要：
An information processing apparatus including a recording medium, a magnetic material having a predetermined magnetization pattern with respect to the recording medium, a first device for detecting the magnetization pattern of the magnetic material, a second device for detecting a change of the recording medium and a third device for driving the recording medium and the second device relative to each other, based on a signal from the first device.
