Halo Reach not working anymore

So I’ve been attempting to go back & play through Reach again but failing. My original disc was cracked in the center due to the case. So I figured this was the issue. So I went out & got another copy of the game. The new disc is spotless. It works a little better but still keeps freezing or saying the disc is unreadable. I have the game installed & it’s still doing this. I never had any issues before with Reach. My 360 also runs other games just fine so I’m pretty sure it’s not my console. I even tried cleaning the tray area. Nothing works. Is anybody else experiencing this? Why is Reach not working anymore?

Probably a faulty disc? That’s very unfortunate for that to happen, other than that suggestion I’m sorry to say I don’t know.
