Blu-ray - 3rd Gen Optical Disc Format
• At CES 2008 Warner announced to publish all future titles exclusively on Blu-ray discs
• Balance of power shifted from almost equal weight to clear overweight of Blu-ray titles
• Re-tailers chose to drop the HD-DVD players and titles
• On Feb 19th 2008 Toshiba announced withdrawal from HD-DVD business
• HD-DVD might survive in Chinese market
Significant R&D resources so far bound in efforts of respective camps to push their format now becoming free

Optical Storage - Success Factors
• Optical storage success factors and key differentiators compared with e.g. HDD and solid-state:
• media removability & exchangeability – expandable capacity– tangibility – privacy & security
• media longevity • low-cost read-only and recordable media
Any successor standard and product has to maintain these features!

Future Optical Media – “Killer Applications” (1/2)
• Continuous progress of display technology requires new content formats
• Increased Spatial Resolution– NHK has demoed 8K at NAB and IBC 2007 – Test broadcasts may start 2016– Sharp has shown prototypes of 4K LCD panels for professional applications
(e.g. medical) – Consumer panels targeted for 2012– Sony offers a 4k projector
• Increased temporal resolution– 24p and even 60p will hardly be the end of the line
• Increased color gamut – dynamic range– Camera sensors and even LCD panels already offer much more than 8 bit
• 3D, Multi-view
• All these enhancements not addressed by BD!!!!

Future Optical Media – “Killer Applications” (2/2)
• Professional archival • Data-intensive businesses such as media & entertainment, life
sciences, government, etc. are facing a tremendous increase in the amounts of data.
– E.g. 13 TB for 2 hrs uncompressed HD movie – Currently solved by clustered storage concepts (RAID) or magnetic tape– Analog archival is still frequently found in film business
• Very high system performance required– Very large capacity (>1TB per medium) – very high data rate at read/write
• No cost-effective storage technology with longevity and high capacity visible in short/mid-term predictions (<4 years)
• Holographic data storage may fit best
410TB

Future Optical Media - A twofold track
• Demand for backward compatibility mandate “conventional” pit based approach for prerecorded distribution media.
• At least 4-5 times BD capacity (i.e.: > 200 GB per 12cm disc)
• Page based holographic data storage may be alternative for archival purposes (write once media)
• Have to differentiate by significantly increased capacity• Minimum capacity 1TB per media

4th Gen - Technology Options
At least 3 fundamentally different technologies are currently competing to reach >200GB per 12cm disc
• Multi-layer technologies– Multiple (>2) laminated BD layers
Expensive– Microholograms
Low write data rate– 2-photon absorption
Low write data rate, rather low SNR
• Near-field optics (aka Solid Immersion Lens – SIL)• Super Resolution Near-field Structure – SuperRENS

4th Gen – leading R&D activities/players in EU
• SuperRENS• Thomson, Leti, Obducat, Aachen University, Imperial College, Univ. Delft, …
• Near-field • Philips & Lite-on Digital Solutions, Thomson, Univ. Delft, …
• Micro-Holography• TU Berlin, Thomson, Toptica, …
• 2-photon absorption• Storex

Summary and outlook
• Data storage is one of the future key technologies with huge economic impact
• Strong European position including large industrial companies, material, components and equipment suppliers
• Evolutionary “pit-based” media are considered best for content distribution
• Holography is the key technology for archival with capacities >1TB per medium
• Consolidation has happened: It is time to launch the next generation now!
