I want to know the answer to the following question:
How much vinyl can be found at the start of an LP?
All the background I'm provided with is that "A further limitation of the gramophone record is that fidelity steadily declines as playback progresses; there is more vinyl per second available for fine reproduction of high frequencies at the large-diameter beginning of the groove than exist at the smaller-diameters close to the end of the side.". Is that enough to answer the question?
