Operating procedure

The Sound Page Recorder was used for education, mostly in Japan. This device recorded on 9 by 12 inch sheets of paper coated on one side with magnetic oxide that captured sound. The front of the sheet was blank, making it possible to write text or print an image. On the back of the sheets was a film of magnetic oxide that captured sound, while the front was blank, making it possible to write a text or print an image.
