Next-generation DVD is born!

<< OK, there's some confusion whether the transfer-rate it megabits or megabytes. Let's go with the worst-case scenatio:

36 / 8 = 4.5 megs/sec

(51,200 / 4.5) / 60 = 190 minutes

With multi-session, is that so bad? How often do you burn 50+ gigs in one go?

EDIT: typo >>

How about redundancy? (i.e. 10 bits per byte instead of 8)

36 / 10 = 3.6 Mbit/s

(51,200 / 3.6) / 60 = 237.03703703703703703703703703704 minutes, or ~237 minutes. Meaning almost 4 hours.

Sure, you won't burn 50 GBs at once right now, but in the future, with increasing HD-space (up to 200+ GB), 4 hours per 50 GB of data is simply not acceptable.

But by that time we will have new and faster writers. That transfer rate is for the current devices in the drawing-board I guess. I bet that within 12 months when first writers are introduced, writers that are capable of 2x, 3x and maybe even 4x speeds become available. I mean, we aren't writing CD's at 1x speed are we ?

If you need to write 50 gigs in one go, leave it burning for the night. problem solved

Good point. The writing speed will probably increase

Leaving it burning during the night? What? You don't sit behind your PC 24/7? :Q

Nah, only about 12 hours/day *cough*

Does that include breaks and dinner?

Breaks? Dinner? Well, I do eat at work, that takes about 30 minutes from my computer use...

Hmm... well, you must be pretty skinny by now if you eat only once a day

<< The "next generation" of DVDs, able to hold almost six times as much information as current discs, has been unveiled by major technology companies.

The new format, the Blu-ray Disc, will store more than 13 hours of film, compared with the current limit of 133 minutes.

Nine electronics manufacturers have developed the discs, which they hope they will become the standard format, getting rid of the differences between those currently made by individual companies.

The new discs will be able to hold 27 gigabytes of information - compared with the current limit of 4.7 gigabytes. >>

>>




Um, DVD's can hold up to 18GB

eh? I don't think they count that. They don't count it for CD-ROM anyway (That 150k/sec is more like 180k/sec)

Isn't that for dual-layer double-sided discs? That 27 gigs is for one-layer discs. Using dual-layers it goes to 50+gigs. Read the thread.

You forgot breakfast . Excluding breakfast, I eat once a day. But I'm not skinny. I do drink quite alot of water and such after work, so I'm not hungry or anything.

i seriously cant wait till they kill off vhs for good. vhs tapes are so blurry compared to dvd now days. i had to rent good will hunting for school. i didnt settle for vhs... had to have dvd.

<< You forgot breakfast . >>

Nope: breakfast


<< Excluding breakfast, I eat once a day. But I'm not skinny. I do drink quite alot of water and such after work, so I'm not hungry or anything. >>

What's your length and weight?

I'm about 1.80 meter and weigh 60 kg

1.93 meters, about 110 kg. So I'm "somewhat" bigger than you .

Yep, I am a bit on the fat side *cough*

BTW, how the heck did we get so off-topic?

Well, I should be getting thinner now that I eat less and I eat more healthy.

How DID this thing get so off-topic?!?!

you guys started chatting about :-

leaving the burner to burn over night as it took about 4hrs

one of you says you don't sit at the pc 24/7

The other says only 12hrs

Then what about breakfast

and then you ask each other how much you guys weighed.......

nice breakdown for you guys

LOL... thanks for breaking it down for us

how many minutes of full quality HD tv can fit on this 27GB one side? no point if it can't hold an entire hd movie with commentary and special features.

<< That article doesn't say it, but could it be that you could make those new discs in dual-layer as well? You would get 54 gigabytes per side, 108 gigabytes per disc :Q! >>



With that kind of data density, I think discs will be much more delicate to scratches unless some workarounds are considered.

From Nemesis77's post:


<< 1. this new DVD uses the cartridge-system. >>



the cartridges will protect the scratches. i think this idea should've been used for regular dvd's too.

It uses cartridges to protect the disc. And after reading some of the specs, it seems that it can scale to 50+ gigs using dual-layer, but there's no mention of double-sided discs. So it seems that 50+ gigs is the max.
