A surface is provided having disposed therein or thereon a plurality of coded data layers. In accordance with the present invention, a disposable nonwoven undergarment is imparted with a medicinal agent to conveniently administer a medicinal agent to the skin via normal contact, wearer motion, andor body heat. The generator also has a second energy source that supplies a second type of energy to tissue different from the first type of energy. Advantageously, a user that would otherwise be unable to playback an incompatible file through the media organizer due to limitations of the media organizer, is able to execute playback using the media file playback system via interactions with the familiar and centralized interface provided the media organizer. In a preferred embodiment A-B-C is Fe-Hf-O and the Ms of the flux guide layer is greater than 50 times the Ms of the read sensor layer where the read sensor layer is NiFe, Ms is saturation magnetization and is resistivity.
