Starting while at a Silicon Valley startup, Siros Technologies, we explored an alternative approach extnending current optical disk technologies. Here, a spinning disk is written and read by a focused ...

Researchers in China have developed a super-high capacity optical disk format that is claimed to hold up to 125TB of data, reports Hong Kong’s SCMP. The new disks are described as outwardly ...

The most common types are CD, DVD and Blu-ray. As removable media, optical discs superseded the earlier magnetic disk cartridges because they weigh less, have higher capacities and are not subject ...

An earlier removable, rewritable optical disk that also used magnetic technology. Introduced in 1985, magneto-optic (MO) media and drives are no longer manufactured. Refurbished drives and media ...

Researchers in Shanghai have recently determined a way to construct an optical disk with that could store on the order of 200 TB, as per The Register. This would be achieved through the use of a ...

Scientists have discovered a way to use single missing atoms in crystals as memory cells, packing terabytes of data into a ...

Our optical photometry data (obtained with the automated photometry telescope RoboScope ... We discuss the possible origin of variability in these old novae in terms of magnetic activity on the ...

The size of the Airy disk depends on the wavelength of the light (λ) and the numerical aperture (NA) of the objective lens. The spatial resolution of the microscope is determined by the ability to ...

Thin-disk single-cavity dual-comb lasers (TDSCs) offer a promising alternative to traditional dual-comb systems, simplifying the setup and enabling power scaling. Their shared resonator components ...

Fu Yuxi from Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences has developed the ...
