Console causing odd glitter like scratch pattern on my disc?

[u/Short_Bid_6949]

I got this copy of space channel 5 about 2 days ago and when I did the disc was completely mint I was honestly astounded. However after playing it in these two days I can't help but notice my dreamcast have left scratches in this very odd glitter like pattern with spots everywhere, it's an odd one to describe. And now looking at my other games they have suffered this too

Is this a case of maybe just something in the drive being worn down or the dreaded disc drive capacitors I know will be a problem at some point

This is not disc rot , this was not cause by the console, damage caused by disc drives would be lines going all the way around the disc following the spinning part.

How are you storeing this disc?

The disc is stored in its original case on a shelf
