CHIBA, JAPAN -- Two companies supporting the Blu-ray Disc optical disc format unveiled prototype players at the Ceatec 2004 exhibition, taking place here this week.

Among the prototypes was the first Blu-ray Disc drive intended for personal computer use.

The drive is from Pioneer and uses a recently developed system that combines a signal processor and control circuitry for a blue laser and red laser in a single chip. The blue laser is used for Blu-ray Disc and the red laser is used in DVDs, meaning the new drive supports both disc formats. Until now most prototypes made use of multiple chips to accomplish the same task.

Formats supported by the drive include read-only BD-ROM discs, write-once BD-R discs, and dual-layer rewritable BD-RW discs, all at 2x speed, and a host of DVD formats. These include DVD-ROM at 12x, read-only support for DVD-RAM at 2x, DVD+/-R at 8x, DVD+/-RW at 4x, DVD-R dual layer at 2x, and DVD+R dual layer at 2.4x

Set top blu-ray devices, in the six months they've been on market, have been unable to read classic DVD content.

What better way to assure the success of your invention than by making sure your product is born with a complete necessity for its expensive media?

Manufacturers for ROM drives have begun to create dual-type readers and writers, but they've all received slaps on the wrist from Sony, half didn't make it to market. Additionally, Blu-Ray wasn't even selected as the successor to DVD.. The infinitely more compatible AOD from NEC was.

So there's Blu-Ray, trying to muscle its way into the market to **** with consumers and muddy the pool that SHOULD have been cleared up after AOD was selected to succeed DVDs.

Nah, they'll just start putting movies on blue-ray discs so it can be played on the new blue-ray drives.

BTW, whats AOD?

That does sound like Sony though. :rolleyes: Even though Betamax was a better media than VHS, Sony wanted too frigging much to license their technology so VHS was adopted by the great majority of companies and so sounded the death knell for consumer Betamax. :shakehead

Doesn't sound like Sony has learned very much in the last 25 years or so. :scratch:

AOD, advanced optical disc. Made by NEC. It's been selected as the successor to DVD. Also blue laser, but the reference design incorporates a red track-seeking laser that can also be used to read old DVD content.
