I don't believe you will have a chance to do that. Different manufacturers have their own formats although many of the players are from Multak. As far as I know JBK is from USA, not multak (might be wrong).
Even Arirang itself has sometimes different formats between versions. I don't believe that their players are backward compatible. In other words, they are having trouble with their own disks.
Have you got the JBK disk?
Does any body know how to/ a way to use a Arirang midi disc to play in a JBK player OR
use a JBK midi disc to play in an Arirang player?
