P.S. "Disc" or "disk" in your country?

general convention:
* disc - optical media (cd, dvd, blu-ray discs), old school vinyl
*** records (disc jockey), type of brakes on a vehicle, toys and
*** games (frisbee disc golf)
* disk - magnetic media (hard disk, floppy disk)

It's come along the same historical path as "programme" and "program".
One was UK English spelling, the other American.
We've adopted the American version for computers in the UK.

Disc/disk started the same path but that one diverged into what you call
"general convention".

Actually "disk" is the older form.

Nah! Actually "disc" is the older form! :-)

But kidding aside, that's how nomenclature for magnetic disks changed
at HP. First it was 'disc' and later became 'disk' (and 'disc' for
optical media).

See for example http://www.hpmuseum.net/display_item.php?hw=548:

"The 2757A was the first disc memory available for use with HP
computers."

A massive 340KB at only $23500, a complete steal!

[This is just a webpage, but the scanned 'Product Documentation' says
the same.]

[OTOH, you'll also find references to optical drives saying 'disk', so
..... "It depends!" :-)]
