I was interested in how heavily modulated vinyl could be, so I popped
an old record (Long Hot Summer Night, Jimi Hendrix, Track Records
1968) under the microscope for a look. And what did I find? Two
adjacent grooves clearly broken into each other:

If you have a scanner, use it to get a good image of the record:

My old scanner only manages 1200dpi, so it is nothing like as good as
my picture.

Couldn't open your link without registering, BTW, and I don't do that.
