What's the difference between a "disc" and a "disk"? (2023)(support.apple.com)

As a quick and dirty heuristic: the C in disc is for CD (or other optical media).

Apple, the etymology company.

They certainly do have bugs.

[Edit. Sorry, misread your comment as saying "entomology."]

So a floppy disk has a disc inside?

No because they weren't optical, they were magnetic.

Yes it did. They were magnetic disks. And they were floppy. The outer case of a 3.5" was solid but just rip it open and you can see the disk itself is floppy.

Edit: oh right, you're talking about the different spellings. Those were entirely arbitrary. We mixed between the two.

Disc = round part visible

Disk = round part hidden or no round part

Have I got it!?

I think their primary difference is disc = optical, disk = magnetic. That’s what they mention first.

All of that “in the UK”.

Looking at the store, they’re using “SSD Storage” for SSD.

The British spelling was used by Philips when they launched the Compact Disc with Sony.

Disk was used by American companies inventing hard disks, floppy disks etc.

British software often used "disc" for both, e.g. RISC OS on Acorn/ARM/Raspberry Pi [1].

Apple uses “disk” when referring to SSD storage. They still use disc when referring to a CD or DVD

SSD could stand for "SSD Storage Device".

Bring back recursive acronyms!

SSD, of course, stands for Solid State Dis[c,k]...

Solid State Drive, usually, but when it comes to language anything goes.

A disk is any planar circular shape.

A disc is a disk-shaped object, such as in the form of a plastic dingus: Frisbee flying disc.

Presumably this apple page is someone's idea of an April fool, date notwithstanding.

"Disc" is the correct spelling of the flat circular thing.

"Disk" was invented by someone in the 1980s either as an attempt at a trade name, or because they couldn't spell.

Then other people continued the mis spelling.

This must be the right answer.

Does anyone have a spate tire? My tyre popped, probably because someone jammed a 'y' in the middle.

When I was much more active in Reddit did one time a meme for r/peloton of Froome yelling at disc brakes - but wrote it as "Old man yells at disk brakes".

Nobody told me anything so I guessed it was good grammar and such.

But then noticed everyone calls them "disc brakes"

Should be "rotor brakes"
