I stayed and purchased the collection.

Nice catch.
Vertical cut might be favored because more grooves could be crowded onto 
a given space. Data going in and out rather than side to side.
I wonder if anyone came up with the algorythm to do digitize without a 
player?
The only other way to get a long performance would be to utilize 
multiple cutters and strategic breaks, a la film reel changes.
