We have developed a video camera recorder using small-size 80 mm DVD-RAM with the following features: direct playback by selecting a thumbnail, no accidental overwrite, high-quality picture for a long time, playback on PCs with a 4.7 GB DVD-RAM drive, DVD recorders, and future DVD players. We have achieved compatibility with other products meeting "DVD Specifications for Rewritable/Re-recordable Discs Part 3: Video Recording Version 1.0" that is an international standard specification as a video recording format. We provide an easy-to-use operation for users by "Disc Navigation".
