ABSTRACT:
The present invention is a photo compact disk (CD) 10 combined with a disk reading system or player 62 in which the disk 10 has a user markable surface on the opposite side of the disk 10 from the picture information storage surface or layer. The user markable side includes a first space 12 for indicating the contents of the photo CD. A second area 14 is provided for indicating how the photos stored on the CD should be displayed. The second area 14 is divided into tracks 18-24 and each track is divided into photograph frame regions 21. Each picture stored on the compact disk has one four quadrant user markable region 21 where the quadrants indicate whether the picture should be skipped, turned clockwise or counterclockwise 90 degrees or turned 180 degrees before display. The printing which outlines the areas and provides photograph numbers is LED light transparent. The photo CD player 62 includes an LED scanner 64 for scanning the second area as the CD rotates. A timing index track 16 with timing marks thereon aids in the sampling of the user markable areas.
