The photos aren't great at showing the scale. It was like a CD but it was as big as a vinyl record. like this:

Also double-sided. AFAIK there weren't any single-sided LDs, which meant the unused side had to be filled with something else, like this memorable graphic: https://www.youtube.com/watch?v=QwTDdyZTX48
The dead side of A Video Standard [0] was white opaque plastic. Still a physical side, but not a readable one obviously. Closest I’ve seen to a single-sided disc.

Aside from very early prototypes, there were LD singles which were thinner and made more like CD's. Mostly 8" but there were a few 12"s made by Sonopress in Europe.
I wonder why they didn't stamp the same data on both sides?
>On the convenience front, the discs were a foot across, about half a pound, easily damaged, and had to be flipped half way through a film.

there is one picture near the end of the article ("Domesday") that does show the scale relative to a standard keyboard/monitor.

I have never felt older than ready these comments. I started working with interactive media exhibits right in between laserdiscs and mpeg files.

I loved the tension between the quality of analog devices and the convenience of digital.

Same. When I was born, optical storage did not exist in any form. It was vinyl, cassette tapes & floppy disks. Lasers were SoTA things that scientists worked with. Not in consumers' hands.

Then (besides LD & VHS) came the CD, which has gone a bit out of fashion lately.

Then the DVD. Which was popular in its heyday, but also over the hill.

Then Blu-Ray. Not to mention a truckload of recordable & rewrite formats, DVD-RAM, MO discs & what have you. On the computer side, flash & TB hdd's for cheap.

Disclaimer: and I'm not even that old yet! Neither retired or owner of a gray beard.

Same. We never had LD, though an elementary school I went to got one through a tech grant program. I remember watching some science class thing on it and the movie Hook. Though watching things on a 15 inch TV mounted up in the corner of the classroom by the ceiling from a desk somewhere in the middle doesn’t exactly let you see the full picture quality.

Outside of that my only experience was seeing them at Blockbuster or in stores before everyone gave up. I don’t remember if I ever saw the teacher holding the laserdisc, but the racks of them in movie stores let you see how big they were.

Behold, the epsilon turn:

The player stops spinning the disc, rotates the laser around to the other side, then starts spinning the disc in the opposite direction.

Later high end players had lasers on both sides and would “auto-flip” for you.

Vinyl records are just black laserdiscs that are audio only :P Well, some records are jell-o colored, but you know.
