TDK has announced that is has started shipping its BD-R (write-once) and BD-RE (rewritable) Blu-ray Discs.
The four new products include BD-R25 (write once, single-side, single-layer, 25GB); BD-R50 (write once, single-side, dual-layer, 50GB); BD-RE25 (rewritable, single-side, single-layer, 25GB); BD-RE50 (rewritable, single-side, dual-layer, 50GB)
To ensure the new discs will be resistant to scratches and dirt even without external cartridges, they will be coated with TDK's new DURABIS 2 hard coating. DURABIS 2 technology has been specifically formulated for Blu-ray Discs.
Mass production at TDK's Chikumagawa Techno Factory, which specializes in optical discs, will commence upon issue of licensing for the bare disc.
The main features of BD-R and BD-RE Blu-ray Discs include DURABIS 2 coating that provides greater resistance to scratches and dirt (particularly fingerprint smudges), ensuring safe use even without a cartridge. The high-precision spin coating creates a supremely flat cover layer, resulting in highly stabilized recording and playback.
The BD-R disc utilizes a recording layer of an inorganic material which is unaffected by exposure to light, thus offering 'archivability'. The BD-RE disc utilizes a highly sensitive phase-change dye in the recording layer that realizes stabilized characteristics even after as many as 10,000 rewrites.
High-precision stacking technology precisely overlays disc layers, delivering stabilized characteristics on both the upper and lower recording layers in a single-sided, dual-layer (50GB) disc.
Firstly i expected many more comments on this page, considering that blu ray has emerged as the format of the future. Nyways the point i wanted to make is that Sony has done a great job n has to be congratu;ated but what they have to concentrate on is bringing the price of the discs down, it is necessary to get this kind of format into the mainstream and maximize revenue as well as consumer satisfaction. You need volumes, n ur gonna get volumes once the price is affordable. I hope u guyz do it fast............
cheers...........
Seems silly to say that the recording layer is unaffected by exposure to light. I thought it was laser light that records the data. Just because it comes from a laser doesn't say it's not light. You should have said "ambient light". True?

BD-R25 (write once, single-side, single-layer, 25GB); BD-R50 (write once, single-side, dual-layer, 50GB); BD-RE25 (rewritable, single-side, single-layer, 25GB); BD-RE50 (rewritable, single-side, dual-layer, 50GB) ? Do you think all these different products will confuse the average consumer?
UMESH- Blu-ray is a whole new media. For example... CD, DVD... You will not be able to read or write to one of these discs unless you have a multi purpose drive, or just a Blu-ray drive. YAY TDK! This will probably get Sony to anounce PS3's Blu-ray capability! Whooo hooo! Gaming will be a new world for people to experience!
