Lasers could make hard drives faster, simpler and higher density

(Phys.org) —Researchers at the University of California, San Diego have discovered that for a wide range of ferromagnetic materials the direction of magnetization can be completely controlled by polarized light without ...

'3-D towers' of information double data storage areal density

Using well-known patterned media, a team of researchers in France has figured out a way to double the areal density of information by essentially cutting the magnetic media into small pieces and building a "3D tower" out ...

Progress toward terabit-rate high-density recording

Research is closing in on the next-generation of ultra-high-density magneto-optical storage devices that could store more than 6,000 Terabits (6 petabits) of data, more than 70 times the contents of the entire U.S. Library ...

Magnetic materials: Forging ahead with a back-to-basics approach

Scientists have recently started to explore the possibility of using an intrinsic property of the electron known as spin for processing and storing information. Magnetic fields can influence the dynamics of electron spin, ...

New directions in data storage solutions

(PhysOrg.com) -- One day in the not-too-distant future, the entire contents of the Library of Congress might be stored on a device the size of a postage stamp.

In plasmonics, 'optical losses' could bring practical gain

What researchers had thought of as a barrier to developing advanced technologies based on the emerging field of plasmonics is now seen as a potential pathway to practical applications in areas from cancer therapy to nanomanufacturing.

Dance of the nanovortices

It is a familiar phenomenon: if a spinning top is bumped or is set in rotation on an inclined surface, it usually does not move in a straight line, but instead scribes a series of small arches. Researchers at Technische Universität ...

Mars 2020 landing site offers unique opportunities

In 2020, NASA's next rover will launch from Cape Canaveral Air Force Station in Florida and head to the Jezero Crater on Mars. Jezero was once home to an ancient lake-delta system that scientists believe may have captured ...
