Clone Optical Disk ?

I'd like to make back-up and working copies (to use in place of originals, and keep the originals pristine) of certain optical disks I have, both commercial and home made. The home made present no problems as I can simply copy the individual files in the worst case.

I would really like bit-for-bit copies (i.e. clones) for both CDs and DVDs, one for just CDs would help a lot. Can anybody suggest programs for doing this, preferably freeware ? I cannot find CloneCD which seemed to do this.

In my reading on this matter, I have across the "need" to break the encryption on certain commercial DVDs/CDs to copy them. I want to clone them, keeping the encryption, and therefore do not understand the necessity for decryption ?

Here's a link for Clone CD. It's a 21 day trial though. There's no freeware versions. I checked MG's for similar software but anything close to Clone CD isn't freeware either.

 

Thank you for the link mdonah, I'll have work more quickly than my usual leisurely one then
