Green Tune CD-R

Has anyone used these Green Tune Mastering CD-Rs ? I was sent 4 samples from RMGI. Planning to burn at 8x and 16x and compare to TY at the same speeds. Any other ideas for testing the other 2?

Looks interesting Brian.

For many years we used Verbatim "Blue AZO" formula discs with great results.

Be curious to see how these test on Plextools vs TY.

That's the plan. Do you really think that a few less errors will be audible? TY are already very low.

Can you think of any other tests besides comparing 8x and 16x?

Brian, if you have Plextools you can try the 'write transfer test' to see if the discs will be ok with burning at those speeds.

You can also try the 'FE/TE test' & compare the results to your Taiyos prior to burning.

The 2nd test will show if the discs are duds.

Hope this helps.

No. If it's within spec there shouldn't be any audible diff.

How subtle is FE/TE as a pre-burn test? Is it simply a "dud" meter, or are there shades of grey?

IMO it's more a case of 'shades of grey' than a dud meter & to be honest I rarely do it unless I have a new brand of CDR to test or if I'm making a cup of tea & have a few minutes to spare.

Although it will tell you immediately how your discs compare with the Taiyo Yudens.

Here's a couple of quick tests I done (forgot to make the tea though!)
1st is the dud, 2nd is the Taiyo

I did some fairly extensive testing on several discs with the RMG guys in the room some months ago on these (assuming they're the same, "mottled" green discs).

They were good. Not stellar, but really good BLER tests. Left in the sun for days, face up, down, hanging from a rear-view mirror, no changes. Seemed very durable.

No audible difference from other discs in case anyone was going to ask. Did a rip - A/B null with two of the people on the design team in the room with a perfect null from a TY disc. Although for the record, the RMG disc was burn-side-up for four days in direct sunlight and the TY was fresh from the burner.

Not surprised by anything - But seemingly a very "hearty" disc.

Those are the ones ... direct sun test was a good idea. Are you going with them now?

I think I'm going to order a box and mess with 'em for a while. I'm pretty happy with TY's (which had basically the same results in the direct sun test also). I'm more interested in their long-term archival quality than anything else.

And believe me... I was *trying* to find a solid advantage to the RMG's while those guys were here. Thought I had one at one point (a NON perfect null) but I wound up flipping a switch or something and corrected it - Back to a perfect null.

The part that impressed me most was the balance -- You know how you might ramp a disc up to speed and hear the drive "flutter" temporarily -- Not with those. I'm *assuming* that semi-viscous "splatter" on the surface is sprayed on during a spin. If so, that could explain the impressive balance. And that's certainly not a bad thing. But TY's WaterShield seems to benefit from the same process.
