The 62GV first shipped in May 1974. Developed at IBM's Hursley, UK, laboratory under the code name Gulliver with an initial capacity of 5 MB. Subsequent models have 10 MB (62TM) and 14 MB capacities. It used a Swinging Arm actuator with one 14-inch disk. The simple design of the actuator, invented at IBM's UK Hursley Labs, became IBM's most licensed electro-mechanical invention of all time, the actuator and filtration system being adopted in the 1980s eventually for all HDDs, and still universal nearly 40 years and 10 Billion arms later. During its production life the IBM 62GV shipped 177,000 units making it the first HDD known to have shipped in excess of 100,000 units. OEM and Small Systems HDDs This section lists IBM manufactured HDDs offered both as an OEM product and for attachment to IBMs small systems such as the System/3, System/32, /34 & /36 and the AS/400. HDDs are identified by their OEM model number and listed chronologically by date of first customer shipment. IBM 0680 The 0680 first shipped in 1979 on most IBM small systems and the low end of the System/370 as the 3310 direct access storage. The OEM version was announced as the 0680 in September 1981. Developed at IBM's Hursley, UK, laboratory under the code name Piccolo with an initial capacity of up to 65MB, it used six 8-inch disks (210 mm) and had an improved rotary actuator. A double capacity version, the 62SW, shipped in June 1984 but very few units were sold because its price per megabyte was the same as the 62GV. IBM 0676 The 0676 first shipped in November 1982 as a 5247 Disk Storage Unit for the IBM System/23 Datamaster. Developed at the IBM Rochester, MN, laboratory as the 21ED it was an 8-inch HDD with an initial capacity of 15 or 30 MB in 2 or 4 210 mm disks. In 1983 it shipped as the HDD in the 5360 System Unit of the S/36. In 1984 its capacity was doubled by doubling the number of tracks per surface and it was incorporated into the 5362 System Unit of the System/36. IBM 0665 The 0665 first shipped in October 1985 in the system unit for the PC AT (5170). Developed under the code name "Pixie" at IBM Rochester, MN, it was a 5-inch HDD with capacities of 20, 30 and 44 MB. IBM 0667 The 0667
