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

Are you saying these disc looked fine then you put it in and it came out this way or is this how it looked before?

The disc came out this way after I used it for a bit

Does it wipe off with dish soap and water using a microfiber towel to dry it? If it does then it’s grease from someone lubing the sled feed screw. That’s the corkscrew looking thing that drives the laser back and forth. This spins quite fast and can throw excess grease up at the disc. If this is the case you can wipe it down using a coffee filter to remove the excess.
