The primary actual onerous drive was developed by Reynold B. Johnson at IBM, in 1956. Johnson’s staff was working with higher methods to retailer knowledge on issues like magnetic tape. They created methods to retailer info (within the type of bytes) on magnetic disks as a substitute, which might be overwritten with new info as desired. This led to the event of an automatic disk that might learn itself in a way much like a file participant — besides a lot bigger.

The primary commercially obtainable model, RAMAC, had a tough drive that was concerning the dimension of a kitchen pantry. Finally issues received smaller, and IBM moreover developed early floppy disks (within the late 1960s) that might retailer and switch info from pc to pc.
