Question Regarding Blu-ray Disc Durability

[SEGA_Queen]

Hi all,

I got a question regarding the durability of PS3 games and Blu-ray discs in general. Recently, I used my local store's slim PS3 to test out a some games I bought. However, after I was done, I noticed very faint marks on the bottom of the discs. I thought it was dust at first, so I tried wiping the discs with a microfiber cloth. But it turns out, they're actually very faint scratches. Neither of the game discs had any scratches before I put them in the PS3.


I'm kind of confused when it comes to blu-ray scratch resistance. I assumed that even though they aren't 100% scratch proof, the special coating would at least protect them against light scratches. How much damage can a PS3 game take before it becomes unusable?

Probably about the same as a regular disc if not more. I would imagine that the engineers who designed everything took into account that the a scratch on a 700mb CD will ruin much less data than a hypothetical 75gb multi-layer BD-ROM.

I wish there was some sort of quantifiable test using steel wool as an abrasive.
