disk versus disc

[Barry Watzman]

Re:

Curiousity for the day - is there any difference between the use of disk
and disc when describing floppy drives, hard drives etc.? 

I just wondered if one is technically right and the other wrong when it
comes to computing...

The answer is that there is a technically right and wrong usage and
difference between disk and disc.

DISK, with a "K", is technically correct for magnetic media (e.g. floppy
disk)

DISC, with a "C", is technically correct for optical media (e.g. Laser disc,
CD-ROM and DVD discs)
