> For all other uses, disk is preferred in American English and acceptable in Canadian English, and disc otherwise.

A disc jockey is an entertainer who spins records or compact discs to play music.

A discothèque is a nightclub where disc jockeys can perform live, spinning to create a party atmosphere for socializing and dancing.

In the United States, the word was quickly shortened to "disco" and became closely associated with the mirror ball on the ceiling and the eponymous style of music and dancing.

So when new styles of music overtook the nightclubs, they shed the "disco" appellation as well. It seems to still enjoy a lot of use in European cities, though.

The term "disc" for storage predates optical media. "Disc" was the common spelling for a disk (like a floppy disk) on British 8-bit computers like Amstrad CPC or Sinclair Spectrum.[1][2]

It seems like the distinction simply comes from British and American preferences.[3]

I have no idea how Apple jumped to such an arbitrary conclusion.

This is goofy. The difference was originally regional (US/UK), and which caught on depended on which product dominated which sub-market. There's no semantic difference.

And where is the "drive" in an SSD?

Trying to explain arbitrary words with logic always fails.

There was a subculture communicating on FIDOnet about collecting AOL installation media (3.5" disks) and reusing them. Somehow we ended up coining the term "bisk" to refer to AOL's given-away media, and much sadness was had when they moved to CDs.

So add one more to the list: a commercial disk reused for your custom .WAD files can be a bisk.

Tron, if I remember correctly, had DISCS instead of DISKS. And if modern CPUs are RISCy, then maybe modern Intel architecture CPUs are Risky.

The last letter.

A disc looks like a disc, and a disk doesn't look like a disc.

addaon

Always thought that “disc” was the original word for an object of a certain shape. As they evolved for computer storage, we got smaller diskettes… which were abbreviated to disks.

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

Apple, the etymology company.

So a floppy disk has a disc inside?

Disc = round part visible

Disk = round part hidden or no round part

Have I got it!?

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"

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.

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

"Disks" as in floppy disks, are removable also. Some weird seperation choices in this 'article'.

Kinda surprising that the article doesn't mention the actual origin of the words:

"Disc" comes from "discus" (the plate thrown in the Olympics)

"Disk" comes from "diskette" (French for "small disc")

I probably just outed myself as a boomer assuming that was common knowledge.
