Ongoing History Daily: More interesting facts about vinyl, part 2

Here’s a fact about playing vinyl records. Do they sound consistently good all the way through? In other words, does the music sound as good nearer to the outside of the record as it does as the tonearm moves closer to the centre label? No.

The outer grooves move faster under the stylus, meaning it has to wiggle less per rotational inch. That translates into less distortion. But as the tonearm approaches the centre of the record, the available space for grooves is less, creating what’s known as “inner groove distortion”—and there’s not much anyone can do about it, because this is an inherent limitation of vinyl.

It also explains why some acts put what they consider their best songs as tracks one, two or three on the side of an LP. They want them to have the best sonic quality.
