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

People will buy anything as long as it's expensive.

I hate when vinyl records get magnetized!

The laser will not degrade the CD.
Some CDs get rot as mentioned above.

The only concern I would have would be that it might be getting hot inside the player, and leaving a CD in a hot place for a long time can cause it to delaminate (rot).

Find something else to worry about.

None of my pre-recorded/store bought CDs have degraded unless scratched or otherwise damaged.  The CD-Rs that I burned have shown substantial degradation somewhere in the 50% range.  CD-Rs contain inks while pre-recorded CDs don't.

If you’re still at all concerned then just use a cd of music you don’t really like and don’t care if it’s damaged. You must have at least one of those in your collection.
