#2Tech Tangents is one of the best retro channels on youtube but by retro I dont mean glorified nostalgia either. Shelby puts a lot of work into his videos and likes to showcase what awesome engineering went into some of the early tech that was practically magic. Love the channel and glad to see it on HN.

#5So CAV (constant angular velocity) is an encoding format for laser disks. When something is written with CAV, it is basically analogue data and therefore repeating patterns can be recognized on the disk.

Not simply repeating patterns, readable text from the credits as shown in the video.

#7The live stream of this had more interesting things as well, such as looking at the ink on mimeographs compared to inkjet printing. Long and rambly as live streams tend to be, but it is there if anyone cares.

#8But the opto mechanical parts of a laserdisc reader are way more interesting than a microscope.

Here's where the text comes into focus, pretty cool:

#10Here's a screen capture of the end credits visible on the disc the videos worth it but I do think sometimes you need to start with the money shot
