Physical degradation of CD's


Hello friends,

Please keep in mind that I am new to the digital world and I'm just curious about something....

I have just recently bought two Dac's.  As I've been trying to break them in, I've had a cd player spinning a cd 24/7 on repeat into the dac.

I'm wondering, does the cd laser constantly going over the same pits over and over again, somehow degrade the physical aspect of the cd layer that is being read by the laser?

I know that I wouldn't want to replay my precious vinyl over and over again, but in that case I'm physically dragging a diamond stylus through the record grooves.  

I have no idea if the laser does anything to the bits it's trying to read when kept on 24/7?

Thank you and best wishes to you all,

Don

Sometimes a CD will go bad with age, an issue known as "CD rot."  However, this ties to poor manufacturing practices rather than use.  Poor quality control when the CD was made can result in oxidation of the reflective surface. There can also be adhesive bonding issues or the presence of contaminants. However, none of these problems are caused by how many times a CD has been played.  End users can still damage a CD through scratched surfaces or leaving the CD in hot sunlight, etc., but again, these are not playback issues.
