The IBM Model 3350 (1975) turned the data module into a non-removable head disk assembly of 317 MB capacity that some observers have called the real Winchester and that has remained the fundamental HDD packaging concept to the present day. Since they were so large, we divided them into four partitions, each of which we regarded as a separate hardware device -- analogous to a cassette drive (our other main peripheral storage device). In 1969, IBM charged San Jose project manager Kenneth E. Haughton with developing a direct access storage facility that matched the performance of the high-end IBM 3330 system at a price attractive to low-end System/370 computer customers.

The disks, spindle and bearings, head-positioning carriage and head-arm assemblies were all incorporated into a removable sealed cartridge called the IBM 3348 Data Module, invented by Richard B. Mulvany and Rudolf W. Lissner, with capacities of 35 and 70 MB. The simple design of the 62GV (Gulliver) drive,[14] invented at IBM's UK Hursley Labs, became IBM's most licensed electro-mechanical invention[15] of all time, being adopted in the 1980s for all HDDs, and still used nearly 40 years and 10 billion arms later. The term Winchester comes from an early type of disk drive developed by IBM that had 30MB of fixed storage and 30MB of removable storage; so its inventors called it a Winchester in honor of its 30/30 rifle.
