How can I wipe my Blank CD?

[Jay Ray]

I have a CD with itunes files on it, but I try to drag the file into the trash can.

It says: The Item "Tokyo's Sky City.m4v." Will be deleted immediately.
Are you sure you want to continue?

Then I say Delete.

Then I get this message:

If it's a CD-R, then you can't wipe the disc as it's a one time burn per disc. If it happens to be a CD-RW, then sorry, I don't know what the problem is.

Its a DVD-R

When I try to drag something into it, it says this disk cannot be modified.

Okay, I didn't know it was a one time use thing, that kinda sucks.

Thanks.
