Hi

Even though the original playstation games use black bottomed disk the it is just to distigustish between a copy and an orginal easyly.
I would personally recomend the tdk or sony disk as i have never had a issue with these, you can of course use and type but you need to see if the laser in you playstation will read the disk if the are cheap and also cheap disk tend not to have any protection from you scratching the reflective layer off and making then useless

Hope this helps
