HD DVD-Rs, followed by 2X BD-R on the way

Verbatim Corporation, a Mitsubishi Kagaku Media (MKM) brand, announced July availability of HD DVD-R media in Japanese markets.  The company then announced that it will be the first to offer 2X (72Mbps) single-layer 25GB Blu-Ray Recordable and Rewriteable media this July as well.  Verbatim has not announced an estimated shp date for the US. 

The 15GB HD DVD-R media will be thrown into production in the early part of July, however the press release says production of 30GB dual layer HD DVD-R media will begin this month.

Like its DVD-R counterparts, HD DVD-R media will feature the Metal AZO recording dye which Verbatim claims to be highly resistant to ultraviolet light and heat which can wear away at the media.

MKM HD DVD-R media is currently manufactured exclusively in the company's Singapore facility.  The company's Blu-ray recordable media is manufactured exclusively at a facility in Mizushima, Japan.  30GB blue laser Ultra Density Optical (UDO) discs are also manufactured at the same Mizushima facility, and Verbatim employees assure us the transition from UDO-R to BD-R manufacturing is seamless and logical.

Pricing was not announced at time of publication. LG just announced a 4X BD-R burner, but as of now there is no 4X (144Mbps) BD-R media.  Pioneer's Blu-ray recorder became available about a month ago.

How fast is that? I'm guessing it'll take 2 hours to burn 30gb at that speed lol

How many kbit/s is 1X on BD?

1x BD is 36Mbps. I have updated the article to reflect this.

How do they even calculate this? How much data they can pull at a set RPM or what?

Because it seems like CD and DVD x's are arbitrarily chosen.

CDx1 is the speed it goes when playing CD-Audio and that, if I recall correctly, equals to 150 KB/s. Similar DVDx1 is the speed used when playing a DVD movie.

I'm guessing it's similar with HD-DVD and Blue ray.

A figure in rpm would not make sense since the discs does not spin at a constant speed but in fact runs slower the longer into the movie/music you are. Disc's are written and read from the center and outwards and the change in rpm is to ensure a constant data transfer speed needed when playing music and movies.

Note that constant rpm's are used in may drives when the discs are used for datatransfer and not media playback. This also means that fx. many CD-drives claiming 50x speed may in fact only deliver that at the outer edge of the CD!

At 2x, it would take 7 mins to burn a 30gb disc.

Don't you mean 55 mins? I think you're confusing 72Mbps (Bits) with 72MBps (Bytes - capital B).

72Mbps = 9MBps

no lead-in/lead-out time taken, only data write time... so you may add 1 to 1.5 min. to the time, don't know how long these Blue-Laser things will take...

30GB disc ( 1GB = 1000MB, this is general for storage calculations )
at 01x... it will take (30x1000) / (036/8) = 1:51:06
at 02x... it will take (30x1000) / (072/8) = 0:55:33
at 04x... it will take (30x1000) / (144/8) = 0:27:46
at 08x... it will take (30x1000) / (288/8) = 0:13:53
at 16x... it will take (30x1000) / (576/8) = 0:06:56

Does BD use packetwrite tech, doesn't? If so, add 1-1,5 sec, instead of min.

Probably even slower at 4x+, because then the drive would probably have to burn in CAV (I assume) and then you need to use a logarithm to calulate the time... either way, its slower than the theoretical limit.

Yes good point, 4X is the maximum -- so you have to give the drive time to ramp up to that speed (which for CD/DVD burners is the absolute last second of the burn). External hard drive for me!

I don't know if 8x will ever catch on in the mainstream. You're talking 36Mbyte/sec continuous write speed, which most consumer level drives would struggle to provide (even high-end drives have a minimum sustained read rate of 40mbyte/sec at the edge.) As soon as a user tries to open IE, play an MP3, has bittorrent open or hits the swap file the harddrive throughput plumets and the bluray drive is going to hit it's cache and maybe rely on burnproof technology.

I think even 4x might be a struggle, especially with laptop hard drives.

the 36MB/s is exactly 8x speed here... so they may really stop at 8x...

+ they may have something like benchmarking to enable 8x and more... most peoples will go for 4x...

currently I already uses 4x for DVD's and 8x - 16 x for CD's even I can burn at 16x for DVD's and 52x for CD's

20 min for DVD worth the wait if I want good quality burning... and I think 30 min for BD or HD worth more considring the diff in sizes between DVD's ad BD/HD

wow a 30gig burning for less than an hour.sweet
