Viability of Replicating 45-GB HD DVDs Unproven, Panasonic Has Told Studios
There has been no manufacturing feasibility established for the replication of triple-layer 45-GB HD DVD ROM discs, Panasonic has told the major studios in the last few weeks in an effort to debunk Toshibas recent claims to the contrary, according to studio sources familiar with those discussions.
Toshiba introduced the 45-GB HD DVD on the eve of last months Media-Tech Expo in Las Vegas to deflate Blu-rays claim to superiority based on disc capacity (CED May 11 p2). Studios backing HD DVD said they were ecstatic at news the format can accommodate 45 GB of content on a single-sided, triple-layer disc. Although Toshiba never released pricing, sources within the HD DVD camp said the 45-GB disc would cost dimes, not dollars more than producing todays dual-layer DVD-9 -- maybe 3 dimes.
However, Hollywood sources told Consumer Electronics Daily that Panasonic since has mounted a reality check campaign and taken it straight to the studios doorsteps. Panasonics bottom line claim -- not only does the 45-GB HD DVD require tolerances thus far unheard of in the replication world, its based on manufacturing processes that havent even been developed yet.
Panasonic, perhaps Blu-rays staunchest defender of that formats 0.1" form factor over HD DVDs 0.6," has told the studios DVDs manufacturing tolerances (to within plus or minus 10-30 microns) were proven viable in the 1990s. Blu-ray, though built to tighter tolerances to within plus or minus 3 microns, is based on technology proven viable in the last 5 years, it said. By comparison, the triple-layer, 45-GB requires ultra accuracy in production and must be built to within tolerances of plus or minus one micron or less.
Were told Panasonic has characterized this as future technology that cant be proven viable without the required spherical aberration compensation. Accuracy in replication, and the ability of a plant to produce discs within a specifications tolerance, has a direct implication for long-term yields and costs, Panasonic said.
The Panasonic presentations to the studios also sought to debunk Toshibas claims that dual-layer HD DVDs could be produced at costs on par with those of regular dual-layer DVDs, the sources told us. Manufacturing dual-layer HD DVDs requires the same degree of accuracy as Blu-ray ROM discs, Panasonic told the studios. Moreover, theres no way to use existing DVD manufacturing lines for dual-layer HD DVD ROMs, the studios were told. New special vacuum system machinery is required, it said.
