Plextor DVD are real taiyo yuden?

hello
I don’t know how to determine if my dvd are real taiyo yuden… I bought them from nierle.com and they are from ‘plextor’ but if i use dvd identifier they don’t seem to be genuine as when I look about it on videohelp.com i see comments as ‘great alternative for cheap media’…
who can I trust to provide me real taiyo yuden?

Welcome to the forum. Look for a serial number in the dye near the center hub. It should start with GG. That is a pretty good indication of real TY.

In the US we have quite a few TY resellers who are no problem. What country do you need to buy from?

I live in Belgium

here’s the web i bought from

http://www.nierle2.com/s01.php?sid=PG001009486454131222341213122234&shopid=s01&cur=eur&sp=en&ag=1&os=1&br=1&pp=aa&bnr=2532

note the ‘quality by taiyo yuden’ remark !! but the results that plextools are giving me are not satisfying.

thanks for your welcoming post :wink:

They are 100% sure genuine Taiyo Yudens. I just bought 75 of those from Nierle, and they gave great results. Only exception: 1 DVD-R gave a medium error when burning, 2 others had relatively high PIF rates (around 2500 total), but all others burned fantastically (around 100-400 PIF total) in my PX-716A. What exactly are you not satisfied about with your scans?

well when I run autostrategy to determine media quality check it say I shouldn’t be burned at that speed due to the poor mechanical characteristics of the media. or 'the drive may not write correctly at the recording speed you have selected
i am running extra test now… I’ll keep you posted

Plextor sells genuine TYG02 discs. For long, they’ve been the only reliable source of TYG02 here in Europe (together with the Verbatim pastels), and have been considered by many the best source of TY media, superior to Verbatim’s pastels and unbranded TY (don’t ask me why, I don’t know, I’m only reporting what I’ve read on many european forums).

Recently, Plextor’s TYG02 discs in jewelcases seem to be a better choice than Verbatim TYG02 sold in spindles, because of poor packaging of the latter: lots of dust, leading to PIF issues if you’re don’t take notice and then don’t carefully dust the discs. Of course the Verbs in spindles are much cheaper. But the Plextors can be found at a better price than the Verbatim pastels.

You mean FE/TE test? :wink:

FE/TE test estimates the quality of the burn given write speed, but the only way you can actually tell how good the burn quality is by burning the media and then check with PI/PO, Beta/Jitter, Read Transfer Rate and TA tests. AutoStrategy and PoweRec supposed to do the work while burning to maintain the quality within spec.

ok I have only tested blank media with unsatifying results;. as I it was really troublesome to find taiyo yuden disks , resellers here in Belgium are kind of dumb and give me the brand of the dvd while all tha matter to me is the media ID… they don’t know what cmc or tyg02 is.
ok, the TA test is the shortest to do; I got in the inner disc zone as ‘very good’, middle disk zone as excellent , outer disk zone as very good…
that’s relatively ok but I would have liked to have excellent all over the disk… is that possible, I burn those plextor at 8x,
i am wanting to do the pi/po tests… but there are several options such as burst test etc, which one is to chose?
thanks again

Tell me about it. Why do you think I only buy online, from UK shops? It’s not only for the best prices, it’s also because they know what they’re selling (at least SVP and DigitalPromo). Here, they sell you Princo like if it was great media, actully because they can make a better profit with these.

You seem to be unfamiliar with testing. Instead of giving you long explanations here, I prefer to inform you that there is a full section on this site dedicated to learning how to perform quality scans with CDSpeed, take a look there. When you know the basics, then we can discuss further. :wink:

I assume you have a plextor drive since you mentioned plextools in your early post. What you want to do is PI/PO Sum1 test follow by Sum8 test. Let us know.

If you still have concerns please post the serial number on the center hub (indicate also whether there are 1 or two serials on the center hub) and post the other serial number near the dye (might take some angling and a magnifying glass to see it :slight_smile: )
