DVD+R is the write-once version of the DVD+RW format that has been developed in cooperation by Hewlett-Packard, Mitsubishi Chemical, Philips, Ricoh, Sony, and Yamaha. It currently has a single-sided capacity of 4.7GB, and is capable of storing up to 2 hours of MPEG-2 video. Like DVD+RW, DVD+R is a format that has not been approved by the DVD Forum, and therefore the DVD+R products do not bear the typical DVD logo.
