The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks, and established what became the dominant HDD technology. In 1973 the IBM Winchester Drive was introduced with three removable, sealed data modules. * Some observers have noted that the 3340 was known as "Winchester" because its development engineers called it a "30-30" (its two spindles each had a disk capacity of 30 megabytes), the common name of a rifle manufactured by the Winchester Company. 3030 is also the number of the Winchester rifle, so the IBM 3040 was called the Winchester. Not only was the sealed disk protected against dirt, the R/W head could also "fly" on a thin air film, very close to the platter.

In 1971, IBM introduced the first "memory disk," better known today as the "floppy disk." It was an 8-inch flexible plastic disk coated with magnetic iron oxide. Project head Kenneth Haughton named it after the Winchester 30-30 rifle because it was planned to have two 30MB spindles; however, the actual product shipped with two spindles for data modules of either 35MB or 70MB. Western Digital still manufactures its read-write head wafers in Fremont CA. About the time the 3340 was introduced, IBM decided to move sales of disk packs and Data Modules from its Data Products Division (mainframes) to its Information Records The DEC RP04 Disk Drive - Columbia University The term Winchester comes from an early type of disk drive developed by IBM that had 30 MB of fixed storage and 30MB of removable storage; so its inventors called it a Winchester in honor of its 30/30 rifle. Early on the design was focused on two removable 30 megabyte modules. Another term for hard disk drive. Magnetic Head Development specifications of key IBM models (Retrieved on 1.31.15 from: Harker, J., et. Individual drives often required high-current AC power due to the large motors required to spin the large disks. It's called a micro Winchester drive, or rigid micro disk drive.
