Termyn8or -> RE: And The Winner Is: Blu Ray! (2/20/2008 11:07:34 PM)

HAHA. Remember I am a tech.
Blu Ray disks were obsolete before they even hit the market. Yup. The new holographic disks had been invented. Many many terabytes of storage.
Years ago I found out that VHS actually came before beta, but was abandoned by Sony because of the poor quality. Beta was developed by Sony as well as VHS, and the VHS system would wind up licensed to JVC, and subsequently to Matsushita, the parent company of Panasonic, who built most of the earlier VHS decks out there at the time. Anything from a GE to a Magnavox, inside it was Panasonic for many many years.
And then a Harmon Kardon VHS was built by NEC, and an NEC beta was built by Sony. This is fact. Then RCA and a few other brands went with a Hitachi design. Although a decent design it did not perform all that well. Even with five video heads they could not match the perfomance of the Panasonics. Then when VHS hifi came out it became seven heads without a flying erase head. They simply did not have good enough motors.
In the meantime people were looking for better quality. Then SVHS came out, that recorded on metal tape and went to a 7Mhz bandwidth, then ED beta came out with 8.6Mhz.It wasn't all that hard considering beta's higher head to tape speed.
Then LDs came out. In the beginning they were primitive by today's standards, and the "new" models that would play the "new" CLV disks had to have some RAM. That was the breaking point, if they need RAM, why not a processor as well ? Gotta have one anyway. That is when the technology took off and the DVD format came about, shortly thereafter.
Well, first it was CDs, that was audio, as time went by those MPEG formats were invented. Then someone figures out a way to make the laser read alot finer, more tracks, therefore recording more information. It was a "new" kind of laser.
Then we get the Blu Rays which are another "new" kind of laser, and now the holographic disks, which are another new kind of laser.The formats have not really changed, they are just making more and more smaller lasers to get more information on the disk, and going to multi-layer.
But the thing is, as long as we will buy it they will make it.
