Superdrive stop recognizing disks! HELP!!!

When i was trying to reinstall OSX today, i found out that my superdrive in the Macbook Pro stopped recognizing disks including the system disk came with the computer. What's the problem here? im getting very very confused since i tried the system restore disk on my Mac Mini, and it didn't work as well......

So is there any update that ruined my optical drives?? or is there any other possibilities?

Please help me....

thanks in advance

 

can anyone help pls?
