Mark Kryder
Mark Howard Kryder (born October 7, 1943 in Portland, Oregon) was Seagate Corp.'s senior vice president of research and chief technology officer. Kryder holds a Bachelor of Science degree in electrical engineering from Stanford University and a Ph.D. in electrical engineering and physics from the California Institute of Technology. Kryder was elected a member of the National Academy of Engineering in 1994 for contributions to the understanding of magnetic domain behavior and for leadership in information storage research. He is known for "Kryder's law", an observation from the mid-2000s about the increasing capacity of magnetic hard drives. Kryder's law projection A 2005 ''Scientific American'' article, titled "Kryder's Law", described Kryder's observation that magnetic disk areal storage density was then increasing at a rate exceeding Moore's Law. The pace was then much faster than the two-year doubling time of semiconductor chip density posited by Moore's law. In 2005, comm ...

HGST
HGST, Inc. (Hitachi Global Storage Technologies) was a manufacturer of hard disk drives, solid-state drives, and external storage products and services. It was initially a subsidiary of Hitachi, formed through its acquisition of IBM's disk drive business. It was acquired by Western Digital in 2012. However, until October 2015, it was required to operate autonomously from the remainder of the company due to conditions imposed by Chinese regulators. Chinese regulators later permitted Western Digital to begin wider integration of HGST into its main business. By 2018, the HGST brand had been phased out, with its remaining products now marketed under the Western Digital name. History Hitachi Global Storage Technologies was founded on January 6, 2003, as a merger of the hard disk drive businesses of IBM and Hitachi. Hitachi paid IBM US$2.05 billion for its HDD business. On March 8, 2012, Western Digital (WD) acquired Hitachi Global Storage Technologies for $3.9 billion in cash and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco Bay Area
The San Francisco Bay Area, often referred to as simply the Bay Area, is a populous region surrounding the San Francisco, San Pablo, and Suisun Bay estuaries in Northern California. The Bay Area is defined by the Association of Bay Area Governments to include the nine counties that border the aforementioned estuaries: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties that do not border the bay such as Santa Cruz and San Benito (more often included in the Central Coast regions); or San Joaquin, Merced, and Stanislaus (more often included in the Central Valley). The core cities of the Bay Area are San Francisco, San Jose, and Oakland. Home to approximately 7.76 million people, Northern California's nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a comp ...

Perpendicular Magnetic Recording
Perpendicular recording (or perpendicular magnetic recording, PMR), also known as conventional magnetic recording (CMR), is a technology for data recording on magnetic media, particularly hard disks. It was first proven advantageous in 1976 by Shun-ichi Iwasaki, then professor of the Tohoku University in Japan, and first commercially implemented in 2005. The first industry-standard demonstration showing unprecedented advantage of PMR over longitudinal magnetic recording (LMR) at nanoscale dimensions was made in 1998 at IBM Almaden Research Center in collaboration with researchers oData Storage Systems Center(DSSC) – a National Science Foundation (NSF) Engineering Research Center (ERCs) at Carnegie Mellon University (CMU). Advantages Perpendicular recording can deliver more than three times the storage density of traditional longitudinal recording. In 1986, Maxell announced a floppy disk using perpendicular recording that could store . Perpendicular recording was later used ...

Exchange Interaction
In chemistry and physics, the exchange interaction (with an exchange energy and exchange term) is a quantum mechanical effect that only occurs between identical particles. Despite sometimes being called an exchange force in an analogy to classical force, it is not a true force as it lacks a force carrier. The effect is due to the wave function of indistinguishable particles being subject to exchange symmetry, that is, either remaining unchanged (symmetric) or changing sign (antisymmetric) when two particles are exchanged. Both bosons and fermions can experience the exchange interaction. For fermions, this interaction is sometimes called Pauli repulsion and is related to the Pauli exclusion principle. For bosons, the exchange interaction takes the form of an effective attraction that causes identical particles to be found closer together, as in Bose–Einstein condensation. The exchange interaction alters the expectation value of the distance when the wave functions of two or more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Diego Supercomputer Center
The San Diego Supercomputer Center (SDSC) is an organized research unit of the University of California, San Diego (UCSD). SDSC is located at the UCSD campus' Eleanor Roosevelt College east end, immediately north the Hopkins Parking Structure. The current SDSC director is Michael L. Norman, UCSD physics professor, who succeeded noted grid computing pioneer Francine Berman. He was named director September 2010, having been interim director more than a year. SDSC was founded in 1985 and describes its mission as "developing and using technology to advance science." The SDSC was one of the five original NSF Supercomputing Centers and the National Science Foundation (NSF) continues to be a primary funder of the SDSC. Its research pursuits are high performance computing, grid computing, computational biology, geoinformatics, computational physics, computational chemistry, data management, scientific visualization, and computer networking.
