An optical data and image medium having a visual image area and a laser recordable reflective direct-read-after-write data strip in proximity to the image area. The medium is made from photographic film to which data strip is joined. Data may be recorded on the reflective strip by a laser beam prior to, during, or after photographic exposure of the visual image areas, thereby providing a compact record for archival storage of data-visual information. |
