why aren't game disks affected by scratches?

[Kosheh]

Dont ask me why this is here because i dont know what forum to put it in

Ummm, probably gaming discussion. It was right below this one

i have a luigis mansion disk and its really scratched up but when i play it NOT A SINGLE glitch missing model messed up texture or anything but with dvd disks just a few scratches and somewhere it will freeze i just dont get it!

Several small scratches won't do anything. If they're every which way and straight-lines on the disc, it won't affect playback either.

- Discs with circular scratches will skip, and it's hard to fix those scratches too.
- Nintendo disc games read backwards (reads from the middle and scans outward) and are relevant to that gen. so if it's scratches on the edge of the disc, you probably wouldn't notice until either the end of a game or during a random cutscene.
- Blu-ray discs have a protective coating that protects them from most light scratches. Taking a pair of keys to the bottom of a disc will ruin it just the same; once again, Nintendo games are backwards-reading Blu-ray discs just fyi

I have Fire Emblem Path of Radiance, and it's heavily scratched up. There's one huge gash around the middle of the disc that's circular in fashion but and it refuses to play past the first cutscene. It's...actually super frustrating.


..and do models even screw up when it comes to disc scratches? I'd assume some material just wouldn't...play.
