While searching for errors in the texts for FLOP, a doubt arose about the word disk in the English text. We consulted each other and then searched and compared information on the internet.
Well, as far as the field of computing is concerned, the spelling disk is used for magnetic data storage, i.e. floppy or hard disk and their devices. And disc is for optical media, not originally designed for data, such as audio CDs.
In some other professional fields there are also distinctive rules and then in general perhaps disk is more prevalent in American English and the opposite in British. However, no source talks about fixed language rules in these versions.
The origin of this duality is in the ancient world. The old Greeks invented the sport of throwing a round, flat object called a diskos. And the ancient Romans made their own word discus in Latin, probably from the original Greek one.
Rome later forcibly took over Greece, and perhaps that is why their version became better known, however , the original Greek one has not died out to this day.
And who actually knows these rules? So, as far as our group was concerned, all people involved in some sort of computing, often professionally, about half of the individuals were knowledgeable about spelling. Maybe nobody knew about the Greek and Roman origins.
The ignorant half of us were looked at by these people in surprise, how could we not know, what a strange thing. Well, we didn't know. But now we know and that's a good thing and it's thanks to the hard, sometimes exhausting, work on the articles for FLOP.
