cdrs
It doesnt matter what color discs for psx, the main thing for psx is that your burner or whatever u use can read sub-channel data.
Use discs to suit your burner, try afew different brands, if u find one that works for you stick with it.
We could go on for hours about this dye and this coating, just find some discs that dont scratch too easily and that work with your burner.
You may get a few coasters experimenting but everybody needs a mat for their coffee cup!
I used to have a ricoh 8x and it hated maxell (8 out of 10 coasters)
It liked memorex,kodak and verbatim.
Doesnt mean yours will!
