Title: Microscopic photos of vinyl record grooves
Post by: Robert Roaldi on May 06, 2021, 09:39:18 am
Here are a couple of sites with photos and videos along with tech description of equipment used.

 Wow!! Very, very interesting, thanks! I remember seeing a cartoon somewhere with a billboard in it that read something like "Play a vinyl album everyday, they served us well for many years"

That was cool! Brings me back to my former life training to be a TEM/SEM operator back at the end of the 1970s and looking at minutia was so fascinating! Got trained in both material sciences (engineering) and in histology/cytology (biological) which was more interesting of the two facets since I was hard-core into life sciences with my photography back then.

Though I didn't finish the program as my photographic biz was taking off (and making $$$), the science and the scientific methodology I learned became a framework for the analytics used in many projects over the course of these years.

Glad I had the opportunity back yet also grateful life took me along a different path.

I look at those grooves and bumps and at the needle and I think it's a wonder it works at all!  :)

It's a fascinating video.
I had to send a link to my brother Rodney, who was trained as a physicist but ended up building beautiful harpsichords.
I titled my email, "This is what Rodney would do if he had a scanning electron microscope."

I haven't heard his response yet.

Agreed.  How that technology could ever reproduce high quality sound (let alone music) is beyond me.

it's getting those "good vibrations" (quoting a Beach Boys song)
