4x, 8x, 16x DVD and Next Generation Writers (such as HD-DVD)

From Philips page directly: http://www.semiconductors.philips.com/markets/computing/dvd/

Designed primarily for PC use, the Nexperia DVD+RW system solution is capable of supporting record speeds up to 8x. This leap forward in recording speed is achieved by a new approach to optical recorder design: Philips moved the write strategy generator (WSG) to the same board as the laser driver, eliminating the data bottleneck that limited recording speed. The new design also supports disk reading during the record process. This in turn supports a Philips innovation that eliminates most recording errors caused by common defects on the disc surface and ensures higher levels of compatibility with legacy DVD players.

The Philips chipset includes the PNX7850 main processor, the TZA1039 analog processor and the TZA1047 laser power controller. The entire system is designed to work with Philips OPU66.20. For fast time-to-market, Philips offers a kit that includes the DVD+RW chipset, the OPU66.20, and a complete set of design tools.

i don’t know if you ever read the newpage, but the article about this was posted on the 4th. here

sorry, you were just a day late.
I’d like to say good job because i see that you are making a good effort as the new moderator.

Its good to know that there are very dedicated people on this forum who take time out of their lives to give information and help people.:bow: :bigsmile: :bow:

Yeah, I do read the news page at CD Freaks home. Whether a news post is a few hours or days earlier or later does not always matter. Maybe the news was first relayed to Jorg at DVDplusRW.org where I’ve been also a frequent poster. Jorg’s usually pretty fast on DVDplusRW-related news. However, unlike the main news page, forum boards are usually for deeper discussions among the members. I posted it here since it was not already. Also, I feel it’s a relatively new news.

And the embarrassing truth is that I’ve been very lazy in CD Freaks forum. Since I’m now the first moderator of this DVD Hardware forum, I will try to help this board become productive and resourceful for many who are interested in DVD recordable and other related technologies just like the DVDplusRW.org forums and other CD Freaks forum boards.

Anyway, back to DVD.


More Press Release.


For 2nd time in 2 weeks, Philips is moving aggressively to advance DVD+R/RW recording format it co-developed with Hewlett-Packard, Mitsubishi Chemical/Verbatim, Ricoh, Sony and Yamaha, and that’s supported by Dell Computer, Thomson and others. Company plans to announce today (Nov. 4) availability of chipset and reference design that moves write-once DVD+R to 8x recording speed, rewritable DVD+RW to 4x, and will enable speeds up to 16x by next year. Design also incorporates new technology to minimize recording errors such as those caused by fingerprints on disc and other disc defects, Philips said. Purpose of reference design is to give quick time-to-market for optical drive manufactures, said Roger Gregory, Philips mktg. mgr.-PC applications. He told us that although current design was primarily for PC use, it could have future application in home CE recorders. Week earlier, Philips announced reference design for home DVD+R/RW decks offering 4x recording for write-once and rewritable media in time for next year’s 4th quarter. For PC and home recorders, higher speed platforms will require new blank disc formulations that media makers are readying, Gregory said. He told us Philips anticipated “speed race” in PC category, where users had become accustomed to faster and faster rip-and-burn performance from CD-R/RW drives.

To serve needs of PC market, road map for reference design has 4 steps, to be paced 6 months apart, in keeping with PC industry product cycle. First step, announced today, brings 8x speed. Next 3 bring 16x recording and at each point obtains cost reductions through more integrated component designs such as single-chip solutions. Reference design is firmware-upgradable, so drives can be modified or improved as occasion arises, such as when 16x DVD+RW becomes available. He told us 16x was theoretical speed limit that enables manufacturers to use “a relatively cheap mechanical system” that read and wrote continuously. Because higher speeds require more stringent vigilance against data-writing errors, Philips developed “fingerprint compensation” for new reference design. Gregory said drive continuously read disc as it wrote, and laser power was modulated to “burn through” semitransparent obstacle when detected. Advantage, he told us, is elimination of need for defect-management and loss of data space on disc. Meanwhile, for opaque debris or scratch on disc that can’t be burned through, system reverts to defect management methods such as writing data redundantly, then recovering good data when disc is decoded and read. He said data could be recovered with scratch up to 3 mm. For time being, reference design is limited to half-height size drives for desktop PC or external burners. For laptop use, height of optical pickup unit (OPU) must be reduced. Gregory said work was in progress on that at Philips. Besides Philips’ OPU, reference design includes company’s firmware and Nexperia platform chipsets. Kits cost $65 each in volumes of 100,000.

NEC and Toshiba proposed its own post-DVD standard to DVD Forum

Blu-ray seems to be the leading post-DVD standard for now. Taiwan and China will soon have their own as well. The two South Korean conglomerates are among the nine Blu-ray founders. Plus, two European (Philips and Thomson) and five Japanese companies.

Will there be another recordable format war? I think yes, and only bigger and more intense.

Personally, I’d like to have some Serial ATA Blu-ray 4x drives to backup my hard disks now, not in 2004 or 2005.

More thoughts:

The way they do business in Tokyo won’t easily allow idealistic cooperation to create a single recordable format standard to happen. South Korean and Japanese companies do not like to communicate to one another the way European and US companies do. Unless they are forced to do so by central and powerful regime (like the one South Korea still has).

Is NEC wrong to make its own standard for profits? Was Philips bad to create DVD+RW when there were already DVD-RAM and DVD-RW? As long as there are more to gain than to lose, it’s going to be repeated by anyone forever. And there’s something called like the paradox in standard war. All the ongoing things about CD and DVD copyrights that seriously discourage technological developments and commercial distribution will also accelerate and strengthen the move to create the Greater China’s own post-DVD format standard. If I were them, I would, too.

Forum sets course for blue-laser DVD standard


Forum sets course for blue-laser DVD standard

TOKYO — The DVD Forum will use the 0.6-mm bonded disk proposed by NEC Corp. and Toshiba Corp. as the basis of its next-generation DVD standard utilizing a blue laser. The Forum will not consider the rival blue-laser technology backed by the Blu-ray Consortium, which was not formally submitted to the DVD Forum for consideration.

The standards-setting body had formed two groups earlier this year to study the two optical disk systems. The approach advocated by NEC and Toshiba uses the same 0.6-mm disk substrate employed in current DVDs, while the Blu-ray approach uses a disk with a 0.1-mm cover layer.

NEC and Toshiba jointly proposed the Advanced Optical Disk System to the DVD Forum in August, but the Blu-Ray Disk proponents have not taken a similar step. “As there is no practical proposal of 0.1-mm cover layer disk systems, the working group is virtually dormant,” a DVD Forum spokesman said.

The Forum’s steering committee decided at a meeting in Paris on Oct. 29 to set specifications for blue-laser DVD systems using 0.6-mm disks.

Aside from the blue laser, the disk system proposed by NEC and Toshiba maintains features of current DVD disk systems. The numerical aperture of the system’s lens is 0.65 and the disk consists of two 0.6-mm platters bonded back-to-back. Storage capacity is 20 Gbytes per side for a single-layer recordable disk and 15 Gbytes per side for a read-only disk. That’s less than the Blu-Ray disk system, which can story 27 Gbytes per side of a single-layer disk. The Blu-Ray system uses a lens with a numerical aperture of 0.85.

NEC and Toshiba say their specifications are friendly to the current DVD infrastructure and are thus more beneficial to both manufacturers and users than the Blu-ray system.

The Japanese Melco’s Buffalo DVM-4222FB with almost identical specification to the Sony DRU-500A targeted for mid-November release. The announced price is 50,000 Yen but I believe it to be around 40,000 Yen when it hits the Japanese retail stores.



Its IEEE 1394 & USB 2.0 external brother named DVM-4222IUE will also be released soon.

An overview of all the announced next generation DVD+R/+RW drives:


This #57812 thread is being merged with thread #58001.

Computers4sure.com has the TDK 4x DVD+R drives AID+040212BX-N and AID+420GX-N, not in stock yet, both for $350.95 plus $8.99 ground shipping.

I can’t find it here yet:

[Edited] I have added Sony in the title to reflect the next firmware to enable 4x DVD+R writing. :slight_smile:

Is there going to be an OEM version of NEC’s new +RW/-RW DVD burner? If so, will it be branded by NEC or by a diferent make? How will its cost compare to the retail ND-1100A and to the OEM versions of the Sony DRU-500A and the Pioneer DVR-105?

Also, I have heard of other models of these drives, keeping the “ND-1100” part of the model name but with endings other than “A”. Can you tell me more about these drives and how they differ please?

Thanks, Nick

As far as we know,not too much to say on that drive…yet

New Philips 4x DVD+R/+RW Data Drive Enables Faster Write Speed on DVD+R

Royal Philips Electronics (AEX: PHI, NYSE:PHG) will unveil its latest DVD+R/+RW data drive that offers a faster writing speed on DVD+R media. Its 4x write speed on DVD+R media will allow consumers to create 4.7 GByte DVDs containing home videos, photo albums and PC data in less than 15 minutes.[/b]

This DVD+R/+RW 4x data drive is the latest offering to emerge from Philips’ integrated roadmap of high performance DVD+RW products. The drive will combine DVD and CD recording and playback functionality into one compact unit. It will employ Philips’ EasyWrite, an easy way for robust recording, making writing to CD as simple as using the floppy drive.

EasyWrite is compliant with Mount Rainier (a joint standards initiative supported by leading manufacturers worldwide). In addition, Philips’ Seamless Link and Thermo Balance Writing technologies ensure the highest levels of reliability and quality during operation.

Philips is committed to the DVD+R/+RW format giving the end-user the compatibility and convergence that consumers demand. “DVD+R/+RW is the best in class for consumer video recording as well as for all PC applications; all within a single, easy to use format”, says Arthur van der Poel, Member Board of Management of Royal Philips Electronics.” It has the great benefit of being compatible with existing DVD playback devices and adding other formats into products will not result in any performance and compatibility improvements, it only creates confusion at the customer level.”

Mass production of the Philips drive will start early in 2003 and will be made available to both PC OEM customers and in Philips branded kits for the aftermarket.

Key features
4x DVD+R write speed
2.4x DVD+RW rewrite speed
12x DVD read speed
16x CD-R write speed
10x CD-RW rewrite speed
40x CD read speed
