Disklavier

Disklavier Group:

I have a Mark III and the dealer installed music on each of my 16 
memory disks before delivering the piano to my home.

I'd like to somehow backup these memory disks to protect against 
losing the music on them in case of a failure, etc.

I tried to copy 'all songs' of a memory disk to a floppy but can't due 
to copyright.

Any suggestions?
