The drives can also read and write traditional 3. Sony MiniDiscs are magneto-optical, and Sony produces many other formats of magneto-optical media. In a new phenomenon, magnetization melting by photoinduced photoconductors, was discovered in magnetic photoconductors. This article needs additional citations for verification. Because the permittivity is anisotropic, polarized light of different orientations will travel at different speeds.

By default, magneto-optical drives verify information after writing it to the disc, and are able to immediately report any problems to the operating system.

The only physical contact is during recording when a magnetic head is brought into contact with the side of the disc opposite to the laser. September Learn how and when to remove this template message.

During recording, laser power is increased to heat the material to the Curie point in a single spot. Please help improve it or discuss these issues on the magnrto page.

If this wave interacts with a material at which the horizontal component green sinusoid travels at a different speed than the vertical component blue sinusoidthe two components will fall out of the 90 degree phase difference required for circular polarization changing the Kerr Ellipticity.

A self-contained unit holding 16 or more disks and connected by SCSI to a host computer, the library required specialized archival software to store indices of data, and select disks. The results of reflection from a magneto-optic material are known as the magneto-optic Kerr effect not to be confused with the nonlinear Kerr effect.

At high power, the surface heats up more and takes its magnetic charge from the north pole magnetic layer. They were later also offered in Canon products. This requires special media. By using this site, you agree to the Terms of Use and Privacy Policy.

Magneto-optical drives were first offered in NeXT computers. Flopticals are 21 megabyte 3. This page was last edited on 9 Novemberat Pinnacle Micro was a major manufacturer of magneto-optical drives.

This enables an electromagnet positioned on the opposite side of the disc to change the local magnetic polarization. Using a magneto-optical disc optiacl much more like using a diskette drive than a CD-RW drive.

The reflected light has a change in Kerr rotation and Kerr ellipticity which is measured by an analyzer and corresponds to either a logical 0 or 1.

The disc consists of a ferromagnetic material sealed beneath a plastic coating.

A magneto-optic effect is any one of a number of phenomena in which an electromagnetic wave propagates through a medium that has been altered by the presence of a quasistatic magnetic field. Unsourced material may be challenged and removed.
