Etymology
The term "hard disk" is a compound noun, meaning its origin is simply the combination of the two words, "hard" and "disk," each with its own history that explains the combined meaning.
Here is the etymology in easy-to-understand words:
"Disk" (or "Disc"): This word comes from the Greek word diskos, which meant a flat, circular object, like a plate, platter, or a discus (for throwing in sports). The meaning in English has always related to a flat, round surface.
"Hard": This word simply means firm, rigid, or solid, and has roots in Old English (heard).
The Compound Term ("Hard Disk"): The term was created to describe the first magnetic storage device with non-flexible platters.
The first known use of the technology was by IBM in 1956, with the IBM 350 Disk Storage unit. This device used multiple, stacked aluminum platters coated with magnetic material.
Meaning: The component was called a "hard disk" to clearly distinguish it from the older, more flexible magnetic storage media that was already in use at the time, specifically magnetic tape and, later, the original floppy disks (which were flexible sheets housed in a plastic cover).
The key point is that the internal magnetic platter (the "disk") was rigid (the "hard" part), unlike the bendable magnetic material of its predecessors. This rigidity was essential for the high-speed spinning required for the new technology to work. The full name became hard disk drive (HDD), but the storage medium itself was the hard disk.
