Can I ask, if you have a 52x CD-R/RW burner and you have a bunch of 48x CD-Rs, should you burn data at 48x or can it be slower...what will give the best quality?

Imperfections or not you still have the error correction which is designed to eliminate them. And it succeeds. Your discs may need to use less error correction bits, but nevertheless, your data is still exactly the same.

Yeh notorious is right, If the media says it's 48x then that is usually the max tested speed on the media and your disks may not burn faster than that without causing errors.

This isn't actually true - word size on a CD is 14 bit, 8 as usual plus 6 bits error correction. Most discs are far from perfect, but due to the error correction bits they still work perfectly. Slower burn speeds do eradicate imperfections.

This isn't actually true - word size on a CD is 14 bit, 8 as usual plus 6 bits error correction. Most discs are far from perfect, but due to the error correction bits they still work perfectly. Slower burn speeds do eradicate imperfections.
I always burn at 52x too. The only errors I've had are not with the drive, but with the stuff I'm burning or the discs.
Hm the concept of burn "quality" is very strange. For data discs there is no question of quality - it's either perfect or corrupt, the essence of binary.
Some people seem to think that audio WAV files will be more accurate when burned slower on to an audio CD, but your burner still performs CRC checks on the data it burns and will throw up errors if the audio isn't 100% perfect - and I very, very rarely get any errors when I burn audio CDs.
At 52x.

Only burn at high speed if your writer is burn-proof and has buffer underrun protection. Otherwise it'll die very quickly.
The best burn is done at 1x speed for best quality. But unless you are using fancy discs, then chances are you'll not even notice the difference between 16x and 24x say. I can't tell the difference between things made at 52x or less. Even audio.
Data can be burned at any speed however I always find you need to burn audio cd's slowly as they usually crackle when done at a faster speed.
