cdanteek Posted July 18, 2007 Report Share Posted July 18, 2007 NEW TDK BLU-RAY DISCS ACHIEVE HIGH-SPEED 4X RECORDING – TDK Recordable Blu-ray Discs Combine New Speed Milestone with Remarkable Capacities and Revolutionary Durability – GARDEN CITY, NY, July 12, 2007 – TDK, a world leader in digital recording solutions, today announced the launch of two new write-once Blu-ray Discs capable of recording at 4x speed. TDK 4x 25GB BD-R Blu-ray Disc media and the 50GB version will both begin shipping later this summer. Retail pricing is set at $19.99 for a 4x 25GB BD-R25B (recordable), while pricing for the 4x 50GB BD-R50B (recordable) has not been finalized. A TDK 4x 25GB Blu-ray Disc can be fully recorded in 22 minutes, and a TDK 4x 50GB Blu-ray Disc can be fully recorded in 45 minutes, cutting the recording time in half in comparison to 2x Blu-ray Disc media. Additionally, TDK announced that it will offer business customers the world’s first 50 piece spindles of 4x 25GB BD-R Blu-ray Disc media. A pioneer of blue laser recording technology and founding member of the Blu-ray Disc Association, TDK began offering its highly anticipated 2x 25GB recordable and rewritable Blu-ray Disc media in the first quarter of 2006. TDK first shipped mass production samples in December 2005, and with the subsequent issuance of the relevant license, the company immediately commenced full force manufacturing. “Demand for recordable Blu-ray Disc media has been growing rapidly,” noted Bruce Youmans, TDK Vice President of Product Research and Development. “By achieving a 4x recording speed, TDK’s new discs slash recording times in half compared to 2x media, extending the format’s appeal even further by making it as convenient as it is powerful.” He continued, “Our 4x, 50GB and 25GB Blu-ray Disc media products solidify TDK’s role in enabling the achievement of remarkable capacities, fast transfer rates and revolutionary durability for TDK Blu-ray Discs.” The BDA (Blu-ray Disc Association) certified the specification for the new 4x, write-once type Blu-ray Discs, paving the way for their launch. The new discs support recording speeds from 1x to 4x, and like previous TDK Blu-ray Discs, incorporate a recording layer comprised of inorganic material. The discs are further highlighted by TDK’s exclusive DURABIS 2 hard coating technology, an ultra-smooth cover layer created through the innovative spin coating method, and a host of other advanced TDK technologies that enable the creation of high-reliability media. TDK Technologies Make Bare Blu-ray Discs a Reality TDK Blu-ray Discs are manufactured to the highest quality standards at the company’s Chikumagawa Techno Factory in Japan. Outfitted with state of the art technology, the Chikumagawa factory is poised to lead the charge on optical media development well into the future. TDK heavily committed its worldwide engineering resources to Blu-ray, and has created new formulations and manufacturing techniques that constitute revolutionary milestones in recording technology. Because Blu-ray Disc media’s data tracks are quite narrow even in comparison with DVD media, precise, stable interaction between the laser and the recording material is especially critical to ensuring error-free recording and playback. That’s why TDK developed DURABIS 2, an innovative hard coating technology that makes bare Blu-ray Disc media a reality by protecting the disc surface against common contaminants such as scratches and fingerprints. DURABIS 2’s revolutionary resistance to fingerprints and scratches eliminates the need for a cartridge, minimizing manufacturing costs and allowing for the same user experience as with today’s CDs and DVDs. TDK pioneered hard coating technology, and its DURABIS 2 is the ultimate protective coating for Blu-ray Discs. Main Features of TDK 4x Blu-ray Discs 1. 4x recording compatible: Reduces recording time by half compared to 2x disc. A recording layer boasting high sensitivity is utilized for compatibility with 4x recording (144Mbps transfer rate). 4x recording reduces recording time by half compared with the previous 2x disc. 4.7GB of data can be copied in less than 5 minutes, which is comparable to a DVD-R recording speed of 16x. 2. DURABIS 2 coating provides significantly greater resistance to scratches and dirt (particularly fingerprint smudges), ensuring safe use even without a cartridge. Since the area of the laser spot on the Blu-ray Disc is small (about one-fifth that of the DVD), scratches or dirt on the recording surface can have an especially detrimental effect, causing errors. DURABIS 2 overcomes the issue by offering significantly higher resistance to scratches, and exceptional resistance to dirt and grime (particularly fingerprint smudges). 3. Exclusive, high-precision spin coating creates a cover layer with nano-precise smoothness for breakthrough stability. The precision and smoothness of the cover layer is extremely important, because the laser beam must cleanly pass through the cover layer in its path to the recording layer. To form this cover layer, TDK utilizes an exclusive high-precision spin coating method. The thickness of the cover layer is controlled to the nano-level. As a result, the load on the focus servo circuit used to correct laser beam positioning is reduced, enabling breakthrough stability. 4. Recording layer utilizing inorganic material in a metal, dual-layer structure is unaffected by exposure to light, giving it outstanding archivability. Previous write-once optical media such as CD-R and DVD-R utilized organic dye for their recording layers. Write-once type BD-R media is based on a completely new concept for the recording material wherein a two-layer structure composed of silicon (Si) and copper alloy (Cu) inorganic materials is utilized. When heated by the recording laser beam, these melt and the Si and Cu alloy become a composite to form recording marks. Because the material is inorganic, it is not affected by light, and offers superior archivability. About TDK TDK Corporation (NYSE: TDK) is a leading global electronics company based in Japan. It was established in 1935 to commercialize “ferrite,” a key material in electronics and magnetics. The company today is a leader in the development of next-generation technologies such as Blu-ray Disc recording media, an optical disc ideally suited for high-definition video recording. TDK offers a full line of recordable DVD and CD media, digital camcorder tapes, professional data storage solutions including LTO Ultrium media, and much more.

marlinsinger Posted July 19, 2007 Report Share Posted July 19, 2007 Unfortunately, so far I haven't seen any burners that can do 4x yet, though they might be out there. Also still too danged expensive. For burners, players, an disks. Link to comment Share on other sites More sharing options...
gi7omy Posted July 19, 2007 Report Share Posted July 19, 2007 I'll still hold off uintil they either decide what standard will be used (or produce dual-standard drives) At least I never did have a Betamax VCR Link to comment Share on other sites More sharing options...
