A recording layer is described that comprises a magnetizable material configured to store an image represented by magnetized regions of the magnetizable material. The magnetizable material may be brought into proximity with a magnetically responsive display layer, which may cause a change in an optical state of the display layer such that a facsimile of the image represented by the magnetized regions is produced within the display layer.
