making a copy of a copy

Hi,

I have a backup disc (CD-R) I created from a downloaded file. But, the media is not so good. So, I'm thinking of creating a new disc using better media. If I were to that, can I just make a copy of the backup disc I have? I know it's usually bads to make a copy of a copy, but I deleted the files I had. So, I have to redownload it.
Would it be safe to make a copy from the backup or should I get the file again to make a new disc from the file?

Thanks

it's okay to do so...

with disks you are dealing with data, not analog signals - dvddecrypter takes care of the details fairly well (error skipping etc) ;) as long as the disk is fairly clean (and unscratched) , and burned properly in the first place there should be no problems reading it in the pc.
