<p><P>PROBLEM TO BE SOLVED: To provide a magnetic material wire contained in a recording medium which can be used to form an image by an electrophotographic system or the like, and capable of detecting the existence of the recording medium by a non-contact type magnetic signal detection means. <P>SOLUTION: The magnetic material wire is contained in the recording medium, and emits a magnetic signal which can be detected by the non-contact type magnetic signal detection means, and it has a magnetic metallic wire rod whose surface is covered with insulating material, is set so that its coercive force may be 30A/m or less, and has a large Barkhausen effect. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
