Miserable Results with TDK CD-RW

Hi!

I recently bought a TDK CD-RW and was sort of shocked to see the following result after burning the disc using my Plextor PX-712A even after a couple of rewrites:



Code: [Select]
        Average/Second          Maximum/Second          Total
C1               701.5                  1496.0      2966571.0
C2                 2.3                    38.0         9670.0
CU                 0.0                     2.0            3.0





After that I tried to erase the disc and write data using my BenQ DW1655, but each attempt resulted in the disc being ejected and Nero reporting "Invalid media". PlexTools Professional wasn't able to erase the disc either.

The weird thing is that my NEC ND-4551A has no problems with this media:



Code: [Select]
        Average/Second          Maximum/Second          Total
C1                 6.0                    29.0        25285.0
C2                 0.0                     0.0            0.0
CU                 0.0                     0.0            0.0

CMC Magnetics is a quite popular brand, so I guess that it's known by most units. Wondering why my NEC has no problems with this CD-RW, while both my Plextor and BenQ fail miserably.

I've had a lot of trouble with some CD-RW that was cleared simply by cutting back significantly on the write speed. I never had a chance to see if this varied by drive.

CMC, although popular, is one of the crappiest media in terms of quality for CD-R/RWs. I have CMC made CD-Rs that even my plextor CD-RW drive wouldn't accept. It's rated 48X, but can only be reliably written at 16X at most to prevent failure and/or errors.

On the drive side, some burners are picky (eg. my plextor mentioned above). Some burners like Lite-on tend to cooperate better, but writing quality might still questionable. Maybe you just found out that your NEC burner has better compatibility with the CMC media compared to plextor.

Well if they were high-speed CD-RW's you have to get the ones that are at a specific max speed that are compatible with your writer drive.

I recently ran into nothing but trouble when I tried out some 16x high-speed CD-RW's only to find out my writer drive will write them at 12x just fine on the first attempt, but trying to erase them failed. Also I can't use any high-speed CD-RW's that are over 650 MB because the drive will only erase part of the disc. Strange!

The media is rated for 24x and my Plextor can also write to 24x only. My NEC unit (which also supports 32x for Ultra Speed+ media) also offers 16x writing, but I don't have problems with 24x, so no need to test that.

I get terrible burn quality with all my TDK discs (especially my DVDs)

Same here - the only coasters I've managed to create in the past five years or so have all been with TDK CD-Rs, in both an HP drive from a few years ago, and a newer Lite-On.

I would say so. Verbatim's a fairly good choice for burns, at least MCC 004.

Note that for CD-Rs, Verbatim is just the brand. The actual CD-Rs are the same CMC crap. It is very hard to find reliable CD-Rs today, especially in regular brick & mortar stores. If you look around, 99% of them are made in Taiwan, which means they are probably either CMC (most common) or Ritek. It is getting harder and harder to find Made in Japan media like Taiyo Yuden.

DVD blanks is a different story. Verbatim is one of the best, even though they are actually made by (surprise, surprise) CMC! Why? Because even though they are made by CMC, the same company that makes those crappy CD-Rs, for Verbatim DVD blanks, quality control is still held by Mitsubishi. Unfortunately, that is not the case for the CD-Rs.

I have at home around 50 Verbetim cdrs, the coloured ones, (there are around five types of colours:red, blue, green, orange, etc). They are reported as Taiyo Yuden. Last weak i have reinstalled my Win, and saw that the my WinXP SP2 (burned on Verbatim) will die. So i have checked the oder Verbatim Taiyo Yuden cds. They all have the same problem. They are stored in slim cases.

Interestingly, TDK CD-RW's (made by CMC) are the only writable CD media that can be read in the Thomson DVD drives in many Xboxes.  Never understood why that would be, but I've tested it myself. Mine are older 12x discs though. I don't use them for any other purpose because of the poor quality.

Agreed. Many brands I previously used had discs made by Taiyo Yuden (Japan) such as TDK, and Memorex - and not one of those TY discs ended up as coasters, but that was a few years ago and now all what I mostly find are discs made by CMC. Therefore trying to go solely by brand for a quality assurance is absolutely no guarantee whatsoever. To find TY's in a local store is pointless where I live, and the only sure way to find them is by shopping online, and if any are found buy allot of them!

The only brand of CD-R's that I've purchased recently (within six months) that are actually still made by the manufacturer whose name is on the box/discs are those from Sony (called Sony Supremas but there's no identifiable info on the box, just on the disc itself), however I don't know how they stack up quality-wise.

Although CMC discs are considered crap I've never actually had any problems from their CD-R's as of yet, but then again I don't burn at the maximum speed when permanently archiving onto CD-R's.

That's not true, they may be made in the CMC factory (or Moser Baer if they are made in India), but with licensed technology from Mitsubishi. In my experience (burned >1000 of them with about 2 coasters total), they are great quality. To make sure you get the good Mitsubishi stuff, you have to look out for the "Super Azo" sign on the package, as there are also Verbatim-branded media that are not made with Mitsubishi technology.

That was the case couple years ago, when there were 2 Verbatim CD-R lineup, datalife (CMC) and Datalife plus (mitsubishi). However, Verbatim had already revamped their branding and packaging, leaving only the CMC CD-Rs. There is no more "Super-azo" or Datalife plus in stores anymore, unless they are old stock.

For people who don't want to look online, I usually purchase these locally, Maxell CD-Rpro.

They are marketed as a Professional CD-R and they are actually branded Taiyo Yudens.

They go on sale quite a bit around here, YMMV, but I haven't had any issues with these on either my Plextor Premium or PX-712.
