GOD FORBID PCENGINE SUPPORTING A SONY PRODUCT OR ANYTHING EVEN REMOTELY CONNECTED TO THE BIG EVIL CORPORATION... J/K

GOD FORBID PCENGINE SUPPORTING A SONY PRODUCT OR ANYTHING EVEN REMOTELY CONNECTED TO THE BIG EVIL CORPORATION... J/K

Even if SONY didn't support BD, why would I want to support it? I don't like caddies or MO drives. Is there a reason why I should support it over AOD?

pc-engine, to be honest, i couldnt care less... u seem the only one sad enough to be taking this whole thing so seriously....
anyway, sony seemed one of the companies supporting it.... not like i care, it wont come out for years and even then, their use is something that doesnt really touch me....

Some people have been using Sony's Blue Ray machine, costs them around US$3500, for use as backup for D-VHS tapes and a high end DVD player.

I wonder when we will see products base on AOD, but I don't expect them to be out the coming half year.

The situation may look like SACD and DVD-Audio, SACD launched early while the bureaucratic DVD forum delays the launch of DVD-Audio. SACD take the lead and garner better support from the market and DVD-Audio is playing catch up.

Uh, is it just me, or is that thing missing component video ports?

It is using a D port which you can use D->Component cables.

D2 is 480p/525p, D3 is 1080i/1125i, D4 is 720p/750p.

Ok fine, but I do like the AOD idea because it's perfect for what I plan to use it for and it just a lot more convenient than BD.

Sensitivity to dust and scratches is about the same as a DVD.

Arguable...

same protective layer as DVD, over 4x the data density... you do the math...

Let's just say it's less sensitive than BD

and having the same sensitivity as DVD is not really a good thing... technology is supposed to progress, i expect durability-stability to progress as well....

Would you care to explain that statement, without bias of course?

And with a bit of cheap plastic added AOD becomes orders of magnitude more sensitive oh eh

That link was already posted by Nick. That's where I got the info

There's nothing to hide my friend. AOD clearly has more practical advantages than BD.

Let it go...let it go...

In addition, by using a disc structure with a 0.1mm optical transmittance. protection layer, the Blu-ray Disc diminishes aberration caused by disc tilt.

AOD has more problems with disc tilt...

I do not know... just felt like posting factoids as well...

I am still using MO even if I have the DVD+RW. I store all my important things on MO.

It'd be better if they will provide options for users who want cartridge for better protection of the media. i.e. AOD cartridged and bare, BR cartridged and bare.

Let people choose whatever they prefer, and better also have something as small as MO (or even smaller) with cartridge.

all i'm saying is that DVD's are not the king of scrathes, if u know what i mean. of course they should be taken care of and everything, but i would like some sort of indestructible format really... or at least something less scratch-friendly...

However, because of the high NA, the protective layer had to be made thin to limit sensitivity to thickness variations and disk tilt. Therefore, Blu-ray disks are sensitive to dust and scratches, and thus, in their naked (without protective cartridge) form, are not as consumer-friendly as the other two naked optical disk technologies

Of DVD Forum's members, Intel, Nec, Time Warner, Toshiba and IBM support AOD. Personally I hope for AOD as I don't want to return to cartridges as slim drives are the way to go for new PC casing standards. Also, according to Toshiba AOD drives can reuse standard DVD tilt-servos for lens disc distance correction, while Blu-Ray needs more expansive ones in even its first (single speed) implementations. And why the hell go back to groove-only encoding?

 

[Panajev2001a]

Sensitivities to thickness variations and disk tilt are worse, however, due to the wavelength difference

That was for AOD...

Adopting a 0.1mm optical transmittance protection layer,
Blu- ray Disc with a 0.85 NA field lens maintains the same
tolerance for disc tilt as DVD.
