The cutting process accounts for the difference in speed. If you draw an angle out from the center of the record, the space within the angle will contain the same amount of information regardless whether on the edge of the record or near the center. The information gets packed closer together as you move towards the center. You're welcome.

Aaaaaccckkkk!

Thank you, Bernard. You saved me from a sleepless night.
Poor Calvin

Thank you, Bernard!

Ouch.

It's a practice that the computer storage industry changed as they developed techniques to cramp more data onto disks (floppy and hard and compact and digital video disks alike). Many disk-based data storage systems read/write data at different rates depending on how far the data tracks are away from the center of the disks so as to keep the data density less varied throughout the usable surface of the disks. (See, for example, "zone bit recording.)

Another interesting tidbit: CDs read from the center to the outside, the opposite of records.

...and CDs record at a constant linear rate so the rotational speed changes as the read head moves from the center toward the outside of the disk.

If I recall correctly, a CD is recorded in a series of concentric tracks, not a continuous track like a vinyl record. This allows faster indexing -- finding the beginning of the next song when you hit the next button.

How many Gen Z people even know what a record is ...

My "millennial" daughters love vinyl records. I don't think they are going away any time soon. It is so freaking cool to pick up a 60+ year old piece of technology or a recording from the 1920s or even the young Caruso recordings I have from 1901-1903, all of which were recorded acoustically! No electronics. Before the invention of the electronic microphone, and it instantly and simply works even with the latest and greatest advancements in technology.

IOW, what was thought to be obsolete, never even got close to becoming obsolete. How did the high end analog world even survive??? lol

I don't think they're going away.
