HOLY CRAP
ok, so i'm checking out PS3 news, when I discover this:
That's right, 23 friggin GB!!!! *Drools* Apparently the PS3's going to be running on those puppies.... so sexy.. and protected!! Finally. The cd - sheath drives always seemed like a great idea, I never understood why they never caught on, at least for data purposes... *shrugs* now, read more info:
"Nine leading companies have jointly established the basic specifications for a next generation large capacity optical disc video recording format called "Blu-ray Disc". The Blu-ray Disc enables the recording, rewriting and play back of up to 27 gigabytes (GB) of data on a single sided single layer 12cm CD/DVD size disc using a 405nm blue-violet laser. The companies that established the basic specifications for the Blu-ray Disc are:
Hitachi, Ltd.
LG Electronics Inc.
Matsushita Electric Industrial Co., Ltd.
Pioneer Corporation
Royal Philips Electronics
Samsung Electronics Co., Ltd.
Sharp Corporation
Sony Corporation
Thomson Multimedia | |
The format was developed to enable recording, rewriting and playback of high-definition television (HDTV). Blu-ray makes it possible to record over 2 hours of HDTV, or more than 13 hours of SDTV on a 27GB disc. There are also plans for higher capacity discs that are expected to hold up to 54GB of data.
While current optical disc technologies such as DVD, DVD-R, DVD+R, DVD-RW, DVD+RW and DVD-RAM use a red laser to read and write data, the new format uses a blue laser instead, hence the name Blu-ray. The benefit of using a blue laser is that it has a shorter wavelength (405 nanometer) than a red laser (650 nanometer), which means that it's possible to focus the laser beam with even greater precision. This allows data to be packed more tightly on the disc and makes it possible to fit more data on the same size disc. Despite the different type of lasers used, Blu-ray Disc recorders can be made backwards compatible with current red-laser technologies and allow playback of CDs and DVDs.
Specifications
The following formats are part of the Blu-ray Disc specification v1.0:
BD-ROM, which is a read-only format developed for pre-recorded content.
BD-R, which is a recordable format developed for PC data storage.
BD-RW, which is a rewritable format developed for PC data storage.
BD-RE, which is a rewritable format developed for HDTV recording.
A single-layer disc can fit 23.3GB, 25GB or 27GB.
A dual-layer disc can fit 46.6GB, 50GB or 54GB.
At present specification v2.0 is being devised which addresses issues such as the use of video codecs and read / write speeds etc." - PS3 Resource Centre
