Congratulations on purchasing your Regina.  May it give you pleasure
for many years to come.

Regina sold stands in which the discs were stored upright.  I believe
that this is the best for two reasons: (1) they do not press on each
other and (2) you can easily select one to play it.

I do not have a way to store mine upright and they are stacked on the
side.  I've never had a problem and I have about 85 in a stack.
