    But MS is supporting HD-DVD and definitely will not support BR, and also if Sony puts BR in PS3 then MS might have no option but to put HD-DVD in XB2.

    I don't see why they wouldn't put hd-dvd in the system. I think this is a no brainer. THe drives should be about as cheap as a dvd drive . The xpensive part would most likely be the hardware to decode and play the video.

    THe xbox 2 hardware should be more than capable of this though.

    Why would you need "support" for BR?

    As long as the drive conforms to ATAPI/SATA/whatever specs, windows will detect it and use it, regardless of the media size and format.

    This is stupid nonsense, talking about "microsoft will not support BR", how could they NOT support it?

    Microsoft would undoubtedly be supporting HD-DVD, Blu-Ray, and anything else that's viable, wouldn't it? They wouldn't opt to put the likes of Blu-Ray in Xbox 2 since it would help Sony out, but they could scarcely ignore anything high-tech and viable in their OS. And certainly not something backed by Dell and HP.

    If a blue laser drive shows up as a compatible IDE or SCSI block I/O device, Windows will detect and support it just fine.

    In fact, that's exactly what Sony's "Professional Disc For Data" blue laser format is:

    http://www.sony.net/Products/MO-Drive/ProDATA/

    It shows up as a standard 23.3GB drive, with 512 or 2048 byte sectors, that you can format to UDF, NTFS, FAT or whatever filesystem you want.

    Though Sony themselves recommend you use UDF:

    http://www.sony.net/Products/MO-Drive/ProDATA/compatibility/index.html

    But, this drive is NOT a Blu Ray drive:

    Isn't it quite logical Microsoft wants to support as many mediums possible?

    well whoever wins is going to make a ton of money.


    Personaly i don't really like either.

    THey aren't big enough jumps to me to warrent it.

    Wait another 3 or 4 years and then push something new.

    Or go with hd-dvd as it seems it will be cheaper off the ground and work on bluray till its a much bigger jump

    No, 50 gigs on one disc sure isn't "big enough"... :roll:

    Nope it isn't .


    Right now i can put 4.7 on one side of the disc. For 80$ i can go get a dual layer giving me 9.4gigs. I can get a dual sided dual layer disc and put 18.8 in the future.

    so 50 gigs is a nice jump from 4.7 as its almost 11 times as much. But its only a little over 5 times more than dual layer dvd and and 2.5 times more than double sided dual layer discs .

    Its not a great leap.

    Now a 100 gigs we are talking.

    50 gigs may not be much for personal data storage, but for games, movies and multimedia it is.
    BR and HD DVD are not meant to replace hard discs.

    I'm not talking about about replacing harddisks.

    I'm talking about replacing dvd .

    I don't think either are a big enough leap to justify it .


    THe leap from cd to dvd wasn't that big either. But it was big enough to give us better than vhs quality at a time when vhs was aging .

    I just don't see the same happening with blueray right now.

    Looks like no content deal announcements. Or rather, a deal involving a major studio.

    It would be great if both formats come out with recorders right off the bat so we don't have to deal with + and - R and RW balkanization.

    Hardware prices are also an obvious concern.

    And is AACS a done deal? It sounds like it would enable the content-owners to turn on Divx like features. Unique Disc IDs? So it can track how many times you've watched a particular disc and decide if you should pay for a new license?

    yes this is really what i want to see.

    I feel that going to the new laser is a step they didn't need to make if a red laser can fit a 100gbs onto a disk.

    I was at InterOpto`04 in Chiba (by Narita) ltwo weeks ago...since it was a optoelectronics trade show, so neither Sony or Toshiba were demoing their drives. But I was able to glean some information:

    BR and HD-DVD both use the same mastering process. A e-beam writes the ROM in resist, its etched then metal sputtered. The metal mold is then used to press disks. So I can`t see how HD-DVD or BR could have significant cost differences - except for maybe the caddie, but then again, I don`t see anyone complaining about the cost of plastic CD cases. (EDIT: and I can`t see why Pony Canyon couldn`t switch to BR production just as quickly)

    Sony Semiconductor is now in the creating its second generation BR recording laser diode - SLD3233VF, 120mW max power at 408nm. It has also produced multi-beam laser diodes to allow playback of multiple formats with one read head.

    Perhaps more interesting is the development of a read-only BR laser diode, the SLD31, with only 5/10mW max power. It is slated to go into production in Q3 of 2005 (calendar year). Could this be a PS3 component?

    There were no HD-DVD laser diodes presented at InterOpto`04, so I cannot make a comparison.

    The disc arn't made from the EXACT same materials for one thing. Just because they are mass produced in a similar way doesn't mean that actually goes on isn't different.
