I am sorry Dave, but I don't think Sony currently sells a MD data deck.
It is my understanding that they used to sell them but they were very
slow and have been discontinued for years. So, if you want to store
digital computer data to a minidisc, you will most likely be using
modern equipment and have to contend with ATRAC. This puts you back to
using Howard Chu's serial data encryption method or what you retrieve
from the MD will not likely be the same as the data you saved on it.
