Yet Another Optical Disc Technology: PH-DVD - Three Times the Density of Blu-ray
 

PH-DVD has the potential to use red laser technology to push the capacity to more than 100GB per disc, more than 3 times what Blu-ray will be offering and almost 4 times the density of HD-DVDs. With such a high capacity it will be possible to produce high quality, uncompressed, high-definition media that will pave the way for future media standards.
