CD-R media - I'm a bit confused... plz help

I've seen all the discussion going on over here about cd-r media and I got a bit confused:

1st I've seen a lot of discussion about Taiyo Yuden, what exacly is it? is it a company or a special brand of cd's?  where I live (in Israel...) I've never seen anythin called Taiyo Yuden.

2nd, the choice of cd-r's around here is quite small Haven't found any Verbatim, Mitsui or stuff like that, mostly: TDK's and Sony ( made in europe)...

HOW THE HELL CAN I TELL IF THE CD-R'S I'M BUYING R OF HIGH QUALITY???

and: I haven't been able 2 find any decent spindles, so I decided 2 go with:
        Maxell CD-R 80 XL-S 50 cd spindle - can any1 give me his impression of Maxell's cd-r's?

German review, let me translate: "The CD-R says 40x, but only the Benq burner used this speed - with error rates way out of spec. Lite-On achieved 32x, Plextor 20x. The results are similar: From the middle of the CD-R on, error rates increase dramatically. Block error rate is 54.37 errors/sec on average - much too high. The maximum is 350 errors/sec - not acceptable anymore. Our analysis drive found E22 and E32 errors. Quality rating: poor."

I think that this CD-R performs better when you use a lower speed. Try 24x or 16x.

I also bought those Maxell CD-Rs once (the very ones tested in the review which CiTay linked).

I burnt most of them in October, and at least one is already dead now. Stay well away from those, I'd say.

Of the selection you have access to, probably TDK would be the best - at least many forum members are content with TDK most of the time.

B) I also have a problem here.
Well, I have some Samsung 24x certified discs, manufactured by Prodisc (those discs are pretty damn cheap, and Prodisc has pretty good reputation about its quality), that are not sold anymore here.

Now, there are Samsung 48x certified discs, but I bought only ONE, because I don't start blindly buying a pack of 'em without seeing the manufacturer first  .
My doubts were true. those new 48x discs are as cheap as the 24x Samsungs of before, but the manufacturer is not the same. this time it is Plasmon, which I don't have info about. The material is also phthalocyanine/silver (I won't buy cyanine discs).
Discs are made in Singapore (at least, the label says that)

I need advice from anyone here that knows if Plasmon is reliable.

I care much more about high quality/<10 BLER rates/durability than compatibility or burning speed: my burner burns at maximum at 8x (Yamaha 8x4x24xSCSI), and fortunately it looks like it doesn't write a single bit wrong  . True that it doesn't read C2 stuff, but on audio discs I have here (that I write the original CRCs on the in-paper) it doesn't change, so it seems perfect©.

The Maxell CD-R 80XL-S 48x 700MB is a Taiyo Yuden product ... you can easily identify them by taking a look at the inner ring ... is it icy and shows a printed serial number that is not curved and is the CD blue (cyanine), then it is Taiyo Yuden which is TDK's favourite manufacturer
The name was Plex The Ripper, not Jack The Ripper

I agree, the blank TDKs i have are either Taiyo Yuden or Ritek. You can try to guess by having an app read the ATIP of the disc. I myself use CDRidentifier in win32,  but it doesnt seem to like ata drives, and for those you could use something like Nero CD Speed which has an option to identify the media in the menus.

I don't have Sonys, and Maxell had a bad reputation some time ago, and i have never tried that brand again.

Tayo Yuden is a company manufacturing CDRs. They sell CDRs to other brands, like TDK, Fuji, Philips... but these brands not always use Tayo Yuden CDRs.
Here, TDK is quite always made by TDK according to the ATIP.

Buying CDRs that bear the name of a CDR manufacturer. Unfortunately, Tayo Yuden is sold in Japan. You have a list of manufacturer names in the "CDR Media" section of the FAQ, first link.
There is a thread about recognizing Tayo Yuden CDRs in CD Freaks.com, but their forum is currently closed.

I've been getting Fujifilm CD-Rs in the U.S. at a good price, Feurio identifies the discs as Taiyo-Yuden. CDR-Identifier is also indicating that the Fujis are T-Y.

CDRW.org found Fujis that were not Tayo Yuden, but Fuji, and were of inferior quality.

>>>'1st I've seen a lot of discussion about Taiyo Yuden, what exacly is it? is it a company or a special brand of cd's? where I live (in Israel...) I've never seen anythin called Taiyo Yuden.'<<<

taiyo yuden company is based in japan and they make very high quality media. taiyo yuden media is not sold under the name "taiyo yuden", or at least i don't think. instead, they manufacture CD media that gets re-labeled. most recent fujifilm media is taiyo yuden (older fujifilm, like pio said, are not taiyo yuden. i believe most are cyanine ritek, some are fuji)

older sony CD media (like 4 or 5 years ago) is also taiyo yuden, as well as older TDK

there are 3 distinct ways to identify taiyo yuden discs (in addition to what programs like CDR identifier say):

(1) the colour of the recording surface. its green. it is not the very bright green/gold-ish like phthalocyanine  media, and it is also not very dark green/blue that other cyanine or azo media are

(2) the hub of the disc (the part of the disc just before the lead-in) is frosted, "textured". unlike many other brands, where the hub is clear plastic so that you can see right through it

(3) taiyo yuden media is made in japan

thx 4 all the info guys....
well, the Maxell's 50 cd spindle  (CD-R 80 XL-S (X48) ) is made in japan, does that mean that I can be sure it's a TY product?  can I use them safely???  (I haven't used Nero's cd-speed, it makes lots of problems, so I haven't been able 2 ID em yet)...

It is.
It is called "That´s CDR" (brand name)
An below it is printed (in letters just as big)
"Taiyo Yuden Co. LTD"
They are also sold in Mexico.
Oh, and they also have them "plain" (no name, silver)
I'm the one in the picture, sitting on a giant cabbage in Mexico, circa 1978.

New TDK 48x,

ATIP: 97m 15s 17f
Disc Manufacturer: Ritek Co.
Reflective layer: Dye (Short strategy; e.g. Phthalocyanine)

Interesting: I just bought some 48x TDK's also and here's what I got 

Manufacturer: CMC Magnetics 
Code: 97m26s66f
Disc Type: CD-R
Usage: General
Recording Layer: Dye Type 6: Short Strategy (Phthalocyanine)
Recording Speed: n/a
Capacity: 79:59.71 703 MB
Additional Capacity : n/a
Overburn Capacity: 82:07.51 (721 MB)

No problems burning them at 48x, but I feel jipped. CMC Magnetics makes crappy CD-R's.

Moral of the story: double check to make sure you know what you're getting. I will add that Fuji CD-R's (made by TY) work great and are sold at places like K-Mart here in the states. Do stay away from Imation or Memorex...lots of duds from them , in my experience (also made by CMC Magnetics).

Anyone have any experience with Smartbuy blackbottom cd-rs?  They are on sale at a local store, but I haven't picked any up yet.

Actually, the ones I bought are silver, not gold. They came in a 25-pack spindle and have the usual writable surface. However, the last bunch of TDK's I bought a while back were azo or cyanine dye (blue), so I noticed the difference right away (these are the typical light-green phthalocyanine color). Maybe several different manufacturers produce TDK-labeled CD-R's?

In any case, I'm sticking to Fuji from now on!

Oh no, i just bought some discs claiming to be TDK and CDRIdentifier shows:

ATIP:              97m 26s 66f
Disc Manufacturer: CMC Magnetics Corp.
Reflective layer:  Dye (Short strategy; e.g. Phthalocyanine)
Media type:        CD-Recordable
Recording Speeds:  min. unknown - max. unknown
nominal Capacity:  702.82MB (79m 59s 71f / LBA: 359846)

 

TDKs bought at the same place a month ago also claiming to be TDK:

ATIP:              97m 24s 01f
Disc Manufacturer: Taiyo Yuden Company Ltd.
Reflective layer:  Dye (Long strategy; e.g. Cyanine, Azo etc.)
Media type:        CD-Recordable
Recording Speeds:  min. unknown - max. unknown
nominal Capacity:  702.83MB (79m 59s 73f / LBA: 359848)

Notable differences: Taiyo Yuden center hub looks like it was "frozen" while the CMCs look "crystal clear".
Also the Serial number in the hub of Taiyo Yudens is not curved, the ones on CMC's are.

Bottom color on the Taiyo Yuden looks green/aqua, while color on the CMC looks almost silver
On top they all look almost the same silverish with TDK letters and logo, and CDR logo in the exact opposite of  the disc. I think the surface is writteable (no so shiny) but i never write on discs.

I was expecting them to be at least Ritek... *snif*.

Why?
I suspect that you have no more than 3 discs, otherwise, how do you tell them apart?

Oops, I bought 100 of these, under Phillips CDR-80 brandname.  They're all labled "40x," but I've been burning them at 8x anyway because that's how fast my drive is. 

What a rip-off.  If only I had seen all of these sites beforehand... 

Disc Type, Material = CD-R, Phthalocyanine
            ATIP Lead-in = 97m 26s 66f
      Norminal Capacity = 702.83MB (79m 59s 74f)
Disc Manufacturer maybe = CMC,Imation       
  SMART-BURN Speed Limit = 8X

Don't worry about them, mine, burned less than one year ago (10th of march 2002) are dying. Their error rate, freshly burned (16 or 24x, Yamaha CRW3200) is very high (some C2 errors on CD ROMs, according to CD Speed with Memorex DVDMaxx 1648, that is picky, I must admit)

And it's not because of light
