8x Blu-ray Recordable (BD-R) developed by Moser Baer

8x Blu-ray Recordable (BD-R) developed by Moser Baer
Moser BaerMoser Baer India has developed a new Blu-ray Disc Recordable (BD-R) media that is capable of reaching 8x recording speeds. This is twice the speed of the fastest, current available Blu-ray burners, which can now write at 4x maximum. The new discs are 8 times faster than the current HD DVD-R technology, which is still snailing along at 1x. It is also worth noting that HD DVD burners are still extremely rare within the consumer computer market. The new 8x BD-R technology was developed jointly with OM&T, which is the former Optical Research and Development arm of Philips and is now part of Moser Baer.

How fast is 8x BD-R?
An 8x BD-R disc will record at approximately 36 MB/s maximum, which should translate to under 15 minutes for a fully written 25GB single layer BD-R. The total writing timeframe will depend upon the recording technique used. A CLV (Constant Linear Velocity) writing technique will result in a faster total completion time (~12 min) compared to a Z-CLV (Zone Constant Linear Velocity) technique. We will have to wait and see what type of writing technique is utilized by the first 8x BD-R burners.

These faster BD-R recording speeds will be warmly welcomed by computer enthusiasts and Blu-ray consumers, allowing for even faster backups of Blu-ray movie titles. It seems that Blu-ray recording speeds are increasing at a faster pace than DVDR speeds were developed. Blu-ray Recordable drives are far from being widely adopted due to the high price points (among other factors) and we are already seeing recordable disc manufacturers reach near the maximum theoretical speeds for Blu-ray Recordables.

    […] NHK develops 15,000 rpm Blu-ray Disc system Japanese company NHK has developed a professional Blu-ray Disc recording system that can reach approximately 7x consumer BD-R speeds. The rotations per minute limitation for current consumer Blu-ray systems is maxed out at approximately 10,000 rpm. NHK exceeded the current limitation with the help of a new type of flexible BD-R Disc that is a mere 0.1 mm thick, which was jointly developed with Ricoh Corporation, a long time innovator in optical disc technology. In order to playback these new flexible discs inside of a reading device, a new stabilizer plate was developed and added to the player hardware in order to hold the discs steady. Here is some more information from the PC World article. “Engineers at the Science and Technical Research Laboratories (STRL) of Japan’s public broadcaster, NHK (Nippon Hoso Kyokai), are working on an optical disc recording system based on consumer Blu-ray Disc technology that can spin as fast as 15,000 rpm without these problems and demonstrated it last week. It’s needed because broadcast quality HDTV signals of the type NHK records stream at 250M bps (bits per second) making a fast-spinning optical disc a necessity. A 1X Blu-ray Disc records at 36M bps so the new system is equivalent to 7X speed.” While this sounds like an interesting development, I have to wonder why they couldn’t use a standard Blu-ray system if they are only going up to 7x? We have already heard about 8x BD-R media by Moser Baer and consumer Blu-ray burners are expected to reach 12x / 10,000 rpms at some point. With this in mind, the NHK system doesn’t sound so great afterall (unless the consumer 8x BD-R is Z-CLV and the NHK Blu-ray system is CLV). On the other hand, perhaps NHK will be able to refine their system with time and exceed the speeds of consumer Blu-ray systems, possibly hitting faster write speeds than 12x? Even if this new system was able to achieve greater speeds, its’ “purpose” is to record broadcast HD signals and a speed of 7x BD-R is sufficient enough for that. Looking at all of this, I am not very impressed with this new NHK system. […]
