Abstract
An optical disc structure for playback by a read-out device is described. The optical disc structure includes a first layer with first content recorded thereon. A second layer is coupled to the first layer. The second layer has first content and second content recorded thereon. The disc of the present principles makes use of the fact that a less than full capacity DVD9 disc leaves available recording space after the end of program area and required lead-out area on the second of the two data layers of a DVD9 disc.
