Fidjit, I have a number of minidiscs, both HD and the other, smaller capacity kind. When I use the latter, I record on HD capability so that I can download it to the computer for making CDs, just as I do the HD original.

Then I erase the original disc. I keep the contents in "My Library" longer which gives me the option of changing the format somewhat.

I also keep a Master CD on hand of each recording so that if I want another copy of a certain event I can just copy from that CD.
