Hi
Do you want to copy disks one at a time
If so put 2 DVD drives into a midi tower PC
You can get duplicating controllers with upto 3, 5, 7 or more copies made at once
Used by pirates and business alike
Either pre built or kit of parts.
For more money you can get a built in ink jet printer to label the disks
Nowadays DVD readers are hard to find so easier to use DVD writers for source & destination drives
I assumed you would want to copy cd's & dvd's not just cd's
Look on amazon for several suppliers
