I'm not going to lie: I play CD-Rs. Often it's of games that I actually have real copies of. Often enough, it's not. Let's just say I'm doing my part to keep market prices low. No, don't thank me.
Anyway, in the past, I always used TDK CD-Rs with green bottoms burned at 8x. I wish I could tell you exactly what type of dye they use, but at the moment, I can't. Anyway, in my two Duo-RXs, these have always done fine. The systems never seemed to have more trouble reading them than they did real CDs, and the drives never sounded like they were struggling or anything. After hundreds of hours of CD-R gaming, I can't detect any signs of deterioration in either of them.
However, I recently got a Super CD system, and a different phenomenon with it was instantly obvious. When playing my TDK CD-Rs, the drive will occasionally emit a weird "thunk" like sound when it seeks something. Interestingly, this is not accompanied by a noticeable delay in reading the track, as sound tests from certain games seem to prove. However, it happens quite often. In my TDK CD-R burn of Dracula X, the "Op. 13" track in the sound test almost always causes this thunk to happen, especially if I play it after playing a different track later on in the CD.
So, maybe the Super CD system just doesn't like CD-Rs? That's what I was thinking. I was even resigning myself to never playing CD-Rs with this particular console. But then just for the heck of it, I burned a couple of other CD-Rs using my recently purchased, blue-bottom Taiyo Yuden CD-Rs at 16x...
The "thunk" sound doesn't happen with the Taiyo Yudens.
Now, maybe the cause is the 16x burning, or maybe it's that I'm using a different burner from when I burned the TDKs. Unless I buy some TDK CD-Rs again, I won't be able to properly isolate the problem. Anyway, this is a relief, as I can now go back to playing my favorite shooters with the audio tracks pre-amplified (if you haven't tried this, you should).
I do know that the effect of CD-Rs on these old systems is something that people around here worry about a lot. A popular theory is that CD-Rs cause the laser to work harder in order to focus and read the data. It sure seems reasonable to me that subjecting my SCD to 10,000 "thunks" might cause some real mechanical trouble. However, given the ease with which it's reading these Taiyo Yudens, I'm going to keep on playing CD-Rs. It just means I have to reburn some things.
If you have experienced trouble with CD-Rs on your system, and you aren't scared of ever trying them again, I really do recommend spending a few dollars and trying some different brands, and possibly even experimenting with different burners and burning speeds if you can. FWIW, it has always seemed to me, whether making CD-Rs for this system or for others, that the brand is the most important factor.
I guess that's all. I'm off to do some burning!
