Terry Johnson (entrepreneur)
Terry Johnson (March 14, 1935 – July 24, 2010) was an engineer and entrepreneur notable for his pioneering work on hard disk drives (HDD). Johnson's early career included engineering and management roles in magnetic recording at IBM (1964–70) and Memorex (1971–73). He then joined in the development of STC 8000 Super Disk, a high-end, rotary actuator HDD funded by StorageTek. In 1980, he left StorageTek to found a startup, Miniscribe, a manufacturer of 5.25 inch HDDs. In 1985, he started another new company, CoData, that subsequently merged with Conner Peripherals in 1986. CoData's 3.5-inch drive became Conner's first product. In 1985, Johnson co-founded PrairieTek, the first maker of 2.5 inch drives. Terry Johnson died in the Northwest Territories, Canada, when his private aircraft crashed during his return from a canoe trip. Background Terry Johnson was born in Ogden, Utah, on March 14, 1935.

Ramp Load/Unload
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are used to move heavy loads over vertical obstacles. Examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans. Owing to conservation of energy, the same amount of mechanical energy (work) is required to lift a given object by a given vertical distance, disregarding losses ...

Seagate Technology
Seagate Technology Holdings plc is an American data storage company. It was incorporated in 1978 as Shugart Technology and commenced business in 1979. Since 2010, the company has been incorporated in Dublin, Ireland, with operational headquarters in Fremont, California, United States. Seagate developed the first 5.25-inch hard disk drive (HDD), the 5-megabyte ST-506, in 1980. They were a major supplier in the microcomputer market during the 1980s, especially after the introduction of the IBM XT in 1983. Much of their growth has come through their acquisition of competitors. In 1989, Seagate acquired Control Data Corporation's Imprimis division, the makers of CDC's HDD products. Seagate acquired Conner Peripherals in 1996, Maxtor in 2006, and Samsung's HDD business in 2011. Today, Seagate, along with its competitor Western Digital, dominates the HDD market.

IBM Personal Computer XT
The IBM Personal Computer XT (model 5160, often shortened to PC/XT) is the second computer in the IBM Personal Computer line, released on March 8, 1983. Except for the addition of a built-in hard drive and extra expansion slots, it is very similar to the original IBM PC model 5150 from 1981. Name IBM did not specify an expanded form of "XT" on the machine, press releases, brochures or documentation, but some publications expanded the term as "''eXtended Technology''" or just "''eXTended''". Features The XT was regarded as an incremental improvement over the PC and a disappointment compared to the next-generation successor that some had anticipated. Compared to the original IBM PC, the XT has the following major differences: * The number of expansion slots is increased from five to eight * Base RAM is increased to at least 128 KB * 2x32KB ROM ICs replace the previous 6x8KB ROM ICs * A 10 MB hard drive is included as standard equipment * PC DOS 2.0 is included * The ...

Tandy Computers
Tandy Corporation was an American family-owned leather goods company based in Fort Worth, Texas, United States. Tandy Leather was founded in 1919 as a leather supply store. By the end of the 1950s, under the tutelage of then-CEO Charles Tandy, the company expanded into the hobby market, making leather moccasins and coin purses, making huge sales among Scouts, leading to a fast growth in sales. Entering the 1960s, aiming to broaden the company horizon, Charles Tandy acquired a number of craft retail companies, including RadioShack in 1963, then an almost bankrupt chain of electronics stores in Boston. In the 1980s, now led by John Roach as CEO, the corporation started to invest into the personal computer market, being one of the pioneers in the personal computer race, being lauded by the magazine ''Financial World'' as "the driving force at the front-running company in the red-hot personal computer race." In 2000, the Tandy Corporation name was dropped and the entity became t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venture Capital
Venture capital (often abbreviated as VC) is a form of private equity financing that is provided by venture capital firms or funds to startups, early-stage, and emerging companies that have been deemed to have high growth potential or which have demonstrated high growth (in terms of number of employees, annual revenue, scale of operations, etc). Venture capital firms or funds invest in these early-stage companies in exchange for equity, or an ownership stake. Venture capitalists take on the risk of financing risky start-ups in the hopes that some of the firms they support will become successful. Because startups face high uncertainty, VC investments have high rates of failure. The start-ups are usually based on an innovative technology or business model and they are usually from high technology industries, such as information technology (IT), clean technology or biotechnology. The typical venture capital investment occurs after an initial "seed funding" round. The first ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ST506
The ST-506 and ST-412 (sometimes written ST506 and ST412) were early hard disk drive products introduced by Seagate in 1980 and 1981 respectively, that later became construed as hard disk drive interfaces: the ST-506 disk interface and the ST-412 disk interface. Compared to the ST-506 precursor, the ST-412 implemented a refinement to the seek speed, and increased the drive capacity from 5 MB to 10 MB, but was otherwise highly similar. Beginning with its selection as the hard drive subsystem for the original IBM XT disk drive controllers supporting the ST-412 interface grew to become ubiquitous in the personal computer industry, The ST-412 interface and its variants were the de facto industry standard for personal computer hard disks until the advent and wider adoption of the IDE or ATA interface in the early 1990s. Both interfaces used MFM encoding; the subsequent extension of the ST-412 interface, the ST-412HP interface, used RLL encoding for a 50% increase in capacity and ...
