摘要：
A guide system is used with a rotary magnetic recording sheet applicable to a system and method which includes a regulator plate and performs magnetic recording or playback by protruding a magnetic head beyond a regulation level of a recording surface of a rotatable sheet of magnetic recording medium. The regulator plate is located to contact the back surface of the magnetic recording medium and held in such a relative position to the recording medium that the regulation level of the recording surface of the recording medium is protruded toward the recording surface beyond a non-regulation level of the recording surface.
