VCDHD
Do we really need another media standard to worry about?
Last week three distinct entities from different parts of the world, Sprout CD of Ukraine, Russia-based Antrop-Studio, and the Dutch firm VDL ODMS, came together to introduce a new high definition format media called VCDHD, or Versatile Compact Disc High Density, which is said to compete with the current DVD standards.
Features & Specs :

[li]VCDHD holds just as much data as curent single sided DVDs at about 4.7GB, but what the format leaves out is licensing requirements that our good old DVDs hold. [/li][li]According to VCDHD.com the VCDHD media is half the thickness of regular DVDs but are backwards compatible with current DVD players.[/li][li]Other upsides to VCDHD over DVD are the “reduction of errors in the beginning of the information zone” which is possible by an improved manufacturing process and overall improvements in the geometry of the disc. [/li][li]The materials used in manufcturing these discs are also said to not only make the media more reliable, but also to reduce the production time from 6-9 seconds it takes to manufacture a DVD to about 2 seconds to make a VCDHD disc. [/li][li]The rejection level is also decreased to about 1% compared to current processes.[/li][/ul]
Blu-ray and HD-DVD players and movies are set to launch within the next few months and many are already sick of the format war between them. Since these two formats are the top dogs in the media wars it will be impossible for any other formats to be adopted, let alone make make an entrance onto the playing field.
PH-DVD
PH-DVD promises three times the storage density of Blu-ray and HD-DVD discs
Polarizonics Corp (PL), has developed a method of potentially increasing the data storage capacity and read rate of both red and blue laser DVDs by up to three times, a process described as Polar High-definition DVD (PH-DVD) Technology.
This technology exploits the polarization element contained in all current DVD formats which is not being used for the physical encoding of the information on the disc. Polar High-definition will significantly increase both the speed and capacity of DVDs. Applications have been made for patents in respect of this technology.
Specs & Features :
The PH-DVD format can be applied as a modification to increase the data read rate and capacity of any of the competing blue laser formats (such as Sony Blu-Ray and Toshiba HD-DVD).
Moreover, the Polarizonics Technology may provide for a red-laser capability to support HD content. Thus, with the potential for over 100GB discs, this innovation is of particular importance for satisfying the coming demands of increased disc capacity of HD video content of movies and video games.
Importantly Polarizonics Technology requires no change in the disc structure itself, and present mass replication equipment can be used without modification or additional costs. Hence, PT can be brought to market within a very short time scale. The PH-DVD format also introduces a new hardware level suppression of the possibility of unlicensed replication piracy.
Polarizonics Technology (PT) simply introduces optical modulation and detection mechanisms to employ the polarization characteristics which, although are present, are currently unused in physical disc formats.
