PH-DVD promises three times the storage density of Blu-ray and HD-DVD discs

The ink wasn't even dry on the last Blu-ray competitor we reported on, and yet it looks like another has surfaced.  If the current high-definition format wars were not enough, a company called Polarizonics Corp has developed a new standard of high capacity media which promises to increase the capacity of Blu-ray and HD-DVD discs as well as the read rate by a factor of 3 using available polarization techniques. has a press release claiming Brainspark has invested in Polarizonics Corp to help get the technology on its feet. Brainspark is known as an "Internet incubator" as it helps startup companies with great ideas penetrate the market.

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.

According to the press release PH-DVD uses a special polarization technology which requires very little modification to the current manufacturing processes:

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.

Polarizonics Corp already has a list of investors which includes Brainspark as well as private investors to back the company up financially but adoption of another standard or technology may take a little more effort for it to become something of value in the optical storage industry.  Interestingly enough, Polarizonics was looking for an Optical Disc Drive Engineer just last year, claiming:

Start-up company looking for an engineer with experience in building and/or testing optical disc drives and/or optical memory testing stations. It is an exciting ~6 months R&D project, with high salary and possible stock options for a senior candidate. Experience with building of microscopes may also be appropriate. Part-time consulting (e.g., 3 days a week) may be an option. The task at hand is the building of a table-top dynamic testing station for a new optical memory format. Being a part of a small engineering team, including some well known University professors, will be a rewording experiance.

Polarizonics was looking for a $500,000 backer as recently as a month ago.

the numbers are way off... 3 times BD and 4 times HDDVD?
BD is 25GB/layer, with 50GB discs available this year and 100GB next year. if this new tech is "more than 100GB", then it's either 4 times DB or 2 times BD, depending on which BD discs you compare. not 3 :p

nitpicking aside, this tech can very well be used with blue laser, so it's not so much competition as it could be a complement. i hope they can incorporate it into future BD standards fast enough.

and i dont know if holographic storage already encodes data in the beam polarisation, so it'd be interesting if this new tech can lead to capacity increases there... it may even turn out that it was derived from the current holographic storage research

Exactly so.

> " i dont know if holographic storage already encodes data in the beam polarisation, so it'd be interesting if this new tech can lead to capacity increases there"

No, you pretty much need to control the beam polarization during holographic encoding, so you couldn't combine the two techniques. However, even with a red laser, holographic storage already has a data density of at least 20 Tbits/cc, so we're a long way from exploiting that potential.
