The Editors of Encyclopaedia Britannica Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree See Article History.

On optical discs such as compact discs CDs and digital videodiscs DVDs , information is stored as a series of lands, or flat areas, and pits. A laser assembly reads the spinning disc, converting lands and pits into sequences of electric signals.

When the beam hits a land, it is reflected onto a photodiode, which produces an electric signal. Laser beams are scattered by pits, so no signal is generated. Learn More in these related Britannica articles:. They both represent bits as tiny pits in plastic, organized in a long spiral like a phonograph record, written and read with lasers. Laser , a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation.

The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Many different types of lasers have been developed, with highly…. Compact disc CD , a molded plastic disc containing digital data that is scanned by a laser beam for the reproduction of recorded sound and other information. Since its commercial introduction in , the audio CD has almost completely replaced the phonograph disc or record for high-fidelity recorded music.

Coinvented by…. Finally, the distribution of the magnetisation can be read out, reproducing the original signal. The magnetic tape is typically made by embedding magnetic particles approximately 0. The most commonly-used of these was ferric oxide, though chromium dioxide, cobalt, and later pure metal particles were also used.

Analog recording was the most popular method of audio and video recording. Since the late s, however, tape recording has declined in popularity due to digital recording. Examples of digital recording are floppy disks and hard disk drives HDDs. Digital recording has also been carried out on tapes.

When writing, the magnetic medium is heated locally by a laser , which induces a rapid decrease of coercive field. Then, a small magnetic field can be used to switch the magnetisation. The reading process is based on magneto-optical Kerr effect. The magnetic medium are typically amorphous R-Fe-Co thin film R being a rare earth element. Magneto-optical recording is not very popular.

One famous example is Minidisc developed by Sony. Domain propagation memory is also called bubble memory. The basic idea is to control domain wall motion in a magnetic medium that is free of microstructure. Bubble refers to a stable cylindrical domain. Domain propagation memory has high insensitivity to shock and vibration, so its application is usually in space and aeronautics.

Magnetic storage media can be classified as either sequential access memory or random access memory , although in some cases the distinction is not perfectly clear. The access time can be defined as the average time needed to gain access to stored records. Accessing different parts of the wire involves winding the wire forward or backward until the point of interest is found. The time to access this point depends on how far away it is from the starting point. The case of ferrite-core memory is the opposite.

Every core location is immediately accessible at any given time. Hard disks and modern linear serpentine tape drives do not precisely fit into either category. Different spots on the storage media take different amounts of time to access. For a hard disk this time is typically less than 10 ms, but tapes might take as much as s.

Magnetic disk heads and magnetic tape heads cannot pass DC direct current. So the coding schemes for both tape and disk data are designed to minimize the DC offset. Many magnetic disks internally use some form of run-length limited coding and partial-response maximum-likelihood.

As of [update] , common uses of magnetic storage media are for computer data mass storage on hard disks and the recording of analog audio and video works on analog tape. Since much of audio and video production is moving to digital systems, the usage of hard disks is expected to increase at the expense of analog tape. Digital tape and tape libraries are popular for the high capacity data storage of archives and backups.

Floppy disks see some marginal usage, particularly in dealing with older computer systems and software. A new type of magnetic storage, called magnetoresistive random-access memory or MRAM, is being produced that stores data in magnetic bits based on the tunnel magnetoresistance TMR effect.

Its advantage is non-volatility, low power usage, and good shock robustness. The 1st generation that was developed was produced by Everspin Technologies , and utilized field induced writing. Research is also being done by Aleksei Kimel at Radboud University [12] towards the possibility of using terahertz radiation rather than using standard electropulses for writing data on magnetic storage media.

By using terahertz radiation, writing time can be reduced considerably 50x faster then when using standard electropulses. Another advantage is that terahertz radiation generates almost no heat, thus reducing cooling requirements. From Wikipedia, the free encyclopedia.

They also recently performed a variant on this experiment, in which they used a tip with an open ring to probe the magnetic field of propagating untrapped light [1]. Giessen believes these new probing techniques will prove useful in the fabrication of novel optical devices. Photonic Metamaterials from RP Photonics. Wiersma, and Massimo Gurioli. A new theory explains the lack of variation in the refractive indices of atomic gases. Unlike most conventional materials, topological insulators generate harmonics when driven with circularly polarized lasers, which opens a window on their surface electronic properties.

Researchers design radioactive molecules that might have exceptional sensitivity to the symmetry violations explaining the matter-antimatter imbalance of the Universe. Two research teams used a ring-like probe to directly characterize the magnetic field of infrared light in a small cavity.

Optics Refractive-Index Puzzle Explained February 9, A new theory explains the lack of variation in the refractive indices of atomic gases. In fact, some even argue the small planet Pluto is part of a binary system with its largest satellite Charon.

While fewer than two percent of massive of stars in binary systems have magnetic fields, a recent discovery of two massive stars in possession of strong magnetic fields yielded much excitement in the astronomy community. Shultz discovered the magnetic properties of the system as a member of the Binary and Magnetic Interactions in various classes of Stars BinaMIcS consortium.

Epsilon Lupi is estimated to have times the brightness as the Sun and each star has about seven times the mass of the Sun. The stars of the Epsilon Lupi system demonstrate an interesting interaction between magnetic fields. The magnetic discovery of the Epsilon Lupi system will hopefully shed light on how astronomers understand the magnetic fields of large stars as well as the interactions of the magnetospheres of binary systems.
