Will anyone ever need to burn a blue ray. I back up on external HD's that are much cheaper. I stream all my HD movies from my Media center. Isn't the industry moving away from disks altogether
@The Analrapist: Half Analyst Half Therapist: It'll be good for people in commercials, television and film to give their clients a BR screener of their material. Other than that, unless you're making your own home movies to play on your blueray player, it won't be a large market like CDs and DVDs were. Still a good business to get into, but not the same large scale.
Am I the only one that's tired of the nX speeds on optical drives. Twelve times WHAT? A 12x Blu-ray drive must be slower than my old 52x CD-Rom drive right? Why not just list the sustained read and write speeds in mb/s?
@Perk-i: its pretty annoying. whats even better is the class system used for SD cards. apparently, everything uses a different multiplier. i dont know how they set it. for blu-ray, 1x = 4.5MB/s
@Perk-i: The concept of nX marketing is by the same genius who came up with the eject and load button under the disc tray. I should send that person a fruit basket annually to show my appreciation.
Now, I'm no engineer, but I'm pretty sure 12x is equivalent to 1.5 * the speed of an 8x drive. Calling that a slight increase is like saying that someone who is 9'6" is only slightly taller than myself, being 6'4".
I really struggle with the speeds of Blu-ray and DVD burners. It seems like I have had nothing but problems with all DVD's I burn at high rates of speed. I can't say the same for blu-ray as I have only burned at 1x and 2x (though had the capability to burn 4x). I hate to see these faster products come out but then take away future life of what many call "archival". Speed is great but make sure you understand the trade-offs...
@andrelix: I was slowing down the burning process on DVD's because I was getting a lot of pretty coasters for coffee mugs until I got a new system that could handle the faster write speeds. Not to say that is the issue you are facing, but thought I would pass along that useless information.
@Mike Zuniga: That was Unexpected: You know, about an hour ago I was looking at blu-ray burners and then suddenly thought: "When would I ever, ever need to burn a blu-ray disk?" The answer was, of course, never. So I'm thinking at this point I'll just get a bd reader.
I used to work for a Sony plant in Indiana that made DVDs. They are made the same way, and it appears that they are made with the exact same machines. The data is actually molded into the polycarbonate disc.
@Dan Crouse: They're made exactly the same way as DVDs (and CDs for that matter). The only real difference is in the mastering process. When I was last at a pressing plant in Germany (about three years ago I think) they couldn't decide whether to upgrade their equipment for HD or Blu-Ray. At the time, neither format was beating the other. They were thinking to go HD because they could actually modify their existing machinery to cope. If they went Blu-Ray they'd have to replace it all with new kit. I hope to god they didn't go the HD way....
I've watched these lovely little discs being manufactured many, many times and it NEVER ceases to amaze me. Never do I think to myself "oh no, gotta watch the discs being made again". It's great. The lacquer application (picture 6) is my favourite. It's dolloped onto the centre of the disc while it's not moving and then each disc is spun extremely fast and the centrifugal force alone spreads the coating evenly across the disc. Wow.
@deliciousburglar: and yes, the data is etched onto the master (at the mastering stage, funnily enough) first with a laser. the resulting "mothers" and "father" are what's used to produce the "mould" that all the discs are pressed from.
@taking_this_easy: It all looks like a fancy record making operation. Vinyl records, CDs, DVDs, and Blu-Rays are all made the same way, sorta. I cannot wait until the age of the spinning disk is over and all media will be downloadable files.
@mac_kix_windoze: Yes, this is exactly right. The master, also called the "glass master" is a mold of the notches in the disc. If only we could have seen a Polka-Dot-Door video on this factory...
Well... there goes my awesome view of BDs. I always pictured these giant lasers shooting from 50 feet away controlled by little oompa-loompas. Each disk was an adventure to make, and unskilled-laser-aimers would accidentally shoot their colleagues who would vaporize instantly. Finally, in an epic plume of smoke and debris, a disk would emerge.
I don't want Blu-rays anymore... ruined! Ruined I say!

i had an economics prof that wouldn't turn his mic off when he went in the hall to talk with students or when he went to use the restroom. and yeah, i don't remember hearing him wash his hands and if you had personal issues to discuss it was best to wait for office hours. the guy was greata prof, but the added comedy of bathroom noises really made the class worth while. his name was Stormin' Norman.
It's good prices are "going down" but they technically they aren't, at least on the bottom end players. They are just making crappier players, and that's what happened with DVD players too when they were selling below a 100 initially (later on you could get a decent DVD player below a 100, but initially a lot of them were horrible). In a year though it's likely that you will find much better blu-ray players at a lower price.

Like, how long to burn a blu-ray in 8x and 12x?
I want one of those, but still waiting for the prices to drop, specially the blank disc prices.

The cost of the burners (which still are over $200) and the cost/availability of the media (ie: high and rare).
When you can get a DVD burner for $26 and 4.2GB for $0.25 or less... it's hard to justify the extra cost.

Why do you need a blu-ray burner in your PC?

pressing is better and more accurate, probably faster, and each dvd is exactly the same physically (barring errors)

I have another new release for you....
But I was picturing more like Gunka-Lunka's. They're more surly, and thus, cooler.

(Though we got a $90 RCA five or so years ago as VHS tapes started disappearing, and it's indestructible.)
