disc, disk
The normal spelling in British English changed from disk at the time of the original Old English (up to 1150)D (1896) to disc by the time of Old English (up to 1150)D2 (1989); in American English it has remained disk. In computer terminology, however, the American spelling is dominant everywhere (as in hard disk, disk drive, etc.), but in other technical applications, including compact disc and disc camera, it is spelt with a c, not k.
