cd backups humms a lot

[sLANE147]

Hi everyone,

Lately I've been making a lot of ps2 backups and most of them work on my v3 ps2. However, I noticed some humming on several backup cd's. Now I've tried to burn at several speeds (16, 24, 48) and cant really tell why some do make a humming noise. Also the media I use is TDK which should be an A brand.

How fast do you ppl burn your cd's and do you notice a humming sound coming from the drive?
