I want to know the answer to the following question:
What was one requirement issue with discs popular in Britain?
All the background I'm provided with is that "Eight-inch discs with a 2-inch-diameter (51 mm) label became popular for about a decade in Britain, but they cannot be played in full on most modern record players because the tone arm cannot play far enough in toward the center without modification of the equipment.". Is that enough to answer the question?
Answer: yes
