The Hard Drive Turns 50

Today, the hard drive is found everywhere--from the PCs we use daily to MP3 players and memory keys so small you can toss them in your pocket and forget you're carrying around a hard drive. But when the hard drive was first introduced on September 13, 1956, it required a humongous housing and 50 24-inch platters to store 1/2400 as much data as can be fit on today's largest capacity 1-inch hard drives.
Back then, the small team at IBM's San Jose-based lab was seeking a way to replace tape with a storage mechanism that allowed for more-efficient random access to data. The question was, how to bring random-access storage to business computing?
Enter the RAMAC, 1956
IBM's answer to this quandary was the Random Access Method of Accounting and Control, dubbed the RAMAC for expediency. The device's name is a direct reflection of the need for such capabilities in the enterprise. Led by project leader Rey Johnson, IBM's San Jose lab brought the RAMAC 305 to market.
Recalls Al Shugart, who worked as a field engineer at IBM before joining the RAMAC project and went on to later found Seagate Technology: "They were starting from scratch in the lab. The RAMAC was not just a disk drive, it was a whole system. Nobody had made disk drives before."
