Topic: Quick question po

[krellian20]

just wandering kasi bumibili ako ng mga dvd sa astro or other store, bakit hindi gold un disc? Diba dapat gold disc kapag original? Mukang fake kasi parang sayang sa pera.

Thanks.

Anong color pala yon?

Usual colors are silver or light gold.

Wow. Come to think of it, I haven't seen a gold colored R3 DVD in a while.

But I wouldn't worry, dude. If it's from Astro, it's original.

tnx for the reply.

silver. yep its original, but the thing is, the gold one is better since its not easily scratch..

If it's silver, then it's a single-layer disc.

Don't worry about the colors.  Color-coding lang yon ng DVD discs.  Silver is single-layer DVD-ROM; Gold (light champagne-gold) is dual-layer DVD-ROM; Blue is recordable (DVD single and dual layer recordable are both blue, whether DVD-R or DVD+R).

It's not true that the silver discs scratch more easily than the gold ones.

But those official color codes apply only to the originals.  Yung mga fake, they're usually gold even if they're single-layer discs.  The piraters want to fool the buyers into thinking that they got a dual-layer disc, when in fact it's just a single-layer DVD.

The only way to know for sure if your fake gold disc is dual-layer is to check with your computer's DVD drive.

What barrister said, walang kinalaman yan sa kulay. Parehong fragile and subsceptible to scratches ang mga DVD.

my dvd are easily scratched but I think the laser on the drive has some correction capabilities

[barrister]

DVD error correction is found on the disc itself, not on the laser.

The DVD file structure has a BUP file that backs up the IFO file, so that even if the IFO is damaged, the player will read the data on the BUP file to get pointers as to how it should play the disc without an IFO.

Scratches can cause minor data errors that are easily corrected by a DVD's error correction system, which is 10 times more robust than a CD's error correction system. 

However, a very small scratch on a DVD can sometimes be uncorrectable, while a very large scratch can be easily correctable.  It all depends on the orientation and refraction of the scratch.
