It started with branding. Like CD stands for CompactDisc which was a trademarked brand name using this logo.
Edit: I’m wrong. There is a patent for an optical disc that precedes CD and Laserdisc and uses the word Disc on the patent
That’s probably where disc started being used for optical storage. And disk remained being used for magnetic storage.
