David Thompson (engineer)
David A. Thompson is an American electrical engineer and inventor with a long career at IBM. He is noted for his many contributions to magnetic recording technology. Thompson was inducted into the National Inventors Hall of Fame for the invention and development of the thin-film inductive head and the magnetoresistive read head. These heads are now ubiquitous in all hard-disk drives and magnetic tape recorders. Contributions and significance Thin-film inductive head Before the commercialization of thin-film recording heads, the data storage industry used ferrite recording heads. A very important attribute of thin-film recording heads was the ability to fabricate such heads with photolithographic methods, which enabled far better dimensional precision than what had been possible with the cutting, grinding and polishing methods employed for making ferrite heads. Thin-film heads were first commercialized in 1980 in the IBM 3370. Magnetoresistive read head The most important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carnegie Mellon University
Carnegie Mellon University (CMU) is a private research university in Pittsburgh, Pennsylvania. One of its predecessors was established in 1900 by Andrew Carnegie as the Carnegie Technical Schools; it became the Carnegie Institute of Technology in 1912 and began granting four-year degrees in the same year. In 1967, the Carnegie Institute of Technology merged with the Mellon Institute of Industrial Research, founded in 1913 by Andrew Mellon and Richard B. Mellon and formerly a part of the University of Pittsburgh. Carnegie Mellon University has operated as a single institution since the merger.

IBM Master Inventor
IBM Master Inventor is an honorific title bestowed by the IBM Corporation to a qualifying employee. The qualification and appointment to Master Inventor is governed by the value to IBM of an inventor's contribution to the patent portfolio, and through defensive publication. IBM weighs many aspects of an inventor's contributions, including impact of invention through licensing A license (or licence) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit). A license is granted by a party (licensor) to another party (licensee) as an element of an agreeme ..., inclusion in product, and percentage of patents with a measurable impact. IBM also considers an individual's contribution to the inventing community inside IBM, whether by acting as a patent reviewer, or providing feedback and guidance to new inventors. IBM Master Inventor is a privilege and title afforded to IBM inventors who have exhibited sustained inventio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Stripe Card
The term digital card can refer to a physical item, such as a memory card on a camera, or, increasingly since 2017, to the digital content hosted as a virtual card or cloud card, as a digital virtual representation of a physical card. They share a common purpose: Identity Management, Credit card, or Debit card. A non-physical digital card, unlike a Magnetic stripe card can can emulate (imitate) any kind of card. Other common uses include loyalty card and health insurance card; physical driver's license and Social Security card are still mandated by some government agencies. A smartphone or smartwatch can store content from the card issuer; discount offers and news updates can be transmitted wirelessly, via Internet These virtual cards are used in very high volumes by the mass transit sector, replacing paper based tickets and earlier MagStrip cards. History Magnetic recording on steel tape and wire was invented by Valdemar Poulsen in Denmark around 1900 for recording au ...

Bubble Memory
Bubble memory is a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as ''bubbles'' or ''domains'', each storing one bit of data. The material is arranged to form a series of parallel tracks that the bubbles can move along under the action of an external magnetic field. The bubbles are read by moving them to the edge of the material, where they can be read by a conventional magnetic pickup, and then rewritten on the far edge to keep the memory cycling through the material. In operation, bubble memories are similar to delay-line memory systems. Bubble memory started out as a promising technology in the 1970s, offering memory density of an order similar to hard drives, but performance more comparable to core memory, while lacking any moving parts. This led many to consider it a contender for a "universal memory" that could be used for all storage needs. The introduction of dramatically faster semiconductor me ...

Christopher H
Christopher is the English version of a Europe-wide name derived from the Greek name Χριστόφορος (''Christophoros'' or '' Christoforos''). The constituent parts are Χριστός (''Christós''), "Christ" or "Anointed", and φέρειν (''phérein''), "to bear"; hence the "Christ-bearer". As a given name, 'Christopher' has been in use since the 10th century. In English, Christopher may be abbreviated as "Chris", "Topher", and sometimes " Kit". It was frequently the most popular male first name in the United Kingdom, having been in the top twenty in England and Wales from the 1940s until 1995, although it has since dropped out of the top 100. The name is most common in England and not so common in Wales, Scotland, or Ireland. People with the given name Antiquity and Middle Ages * Saint Christopher (died 251), saint venerated by Catholics and Orthodox Christians * Christopher (Domestic of the Schools) (fl. 870s), Byzantine general * Christopher Lekapenos (died 931) ...
