I have a MacBook and lately, every time I insert a blank disc, it spits the disc out. I can hear the drive working for a couple of seconds then the disc comes out. The same thing happens when I insert burned disc. I didn't encounter any problem whenever I insert original discs (audio or films). Please help me. I need to burn a lot of files. 
Thank you!

I've been using the same blanc discs but the problem only came 2 weeks back. Before I can use -/+ r/rw disc with no problems at all. I doubt that it has to do with the discs type
Thank you!
