Burn speed question

[Chewy]

I assume those are made in Tawain by Ritek?

[geno888]

These media are made in Taiwan, but I don't know if they are done by ritek. They are branded Ricoh.

To give you an idea of what they appear, take a look here (I bought my discs on another site: this is only as example)

ricoh has been outsourcing to ritek, if verbatim can do it with cmc, prodisc and MBI, maybe ricoh can too.

[geno888]

I'm scanning the disc right now. 35% in progress...

[geno888]

Done

[Chewy]

now geno, the 12x burn before was burned with a different burner and scanned with a different scanner

[geno888]

ok, now I'll do another test disc with lg @12x

[Chewy]

what's really confusing is the liteon vs benq scans, I know what to look for,
but most people won't have a clue as to how they report the PIF totals and max differently. 1 ecc vs 8 ecc scanning interval.

We will take for granted that 4x and 16x are not good burning speeds for our setups.

[geno888]

Here there is the new scan

[Chewy]

so the 12x is better than 8x(burn speed)
my nec 3550 is the other way around.

[geno888]

As I said previously, it's burner/firmware/media related. And too bad the only way to find is to try and see what is better for each . The only thing that can be generalized is that with newest media the best choice is to burn "around" their certified speed.

I admit that my LG drive surprised me in burning these discs with that results. Until now I thinked that my best burner was the benq 1640, but this LG need more testing (I bought it only for RAM media, but now I'll test thoroughly also with other media )

no more plextor

[geno888]

For your reference, here there are other two scans with LG 4167

The first was burned @8x with latest firmware available DL13.
The second @16x with original firmware DL11 (I'll do tests also with latest firmware). Even if I selected 16x as speed, my drive burned this media @12x.

Okay, after all this, has a manufacturer actually come out and said that media rated at faster speeds has ink that burns poorly at slower speeds or are you just theorizing that based on your results?

[Chewy]

We aren't theorizing, every burner starts slower in the center of the disk,
the dye(not ink) has to accept various burning speeds as the laser travels
out from the center the speed increases. Having said that, I have seen a lot of scans that show worse burns at the begining than at the end. Who knows, there are too many variables to make generalizations.

when you read this, it's a wonder it all works as well as it does
