Philips announces a document that describes High Capacity Recordable discs with a maximum single session time of 98 minutes, 29 seconds, 74 frames on 12 cm discs. For 8cm discs the playing time will be roughly 30 minutes. The recorded High Capacity Recordable is not fully compliant with the Red Book, but will be playable on the majority of the installed base CD players. To avoid any misunderstanding about the compatibility of the High Capacity Recordable Discs: The use of a CD logo is not allowed on this disc.
