  Electrical double layer - Wikipedia, the free encyclopedia
The analogue in a plasma is the double layer.
The earliest model of the electrical double layer is usually attributed to Helmholtz (1879).
Helmholtz treated the double layer mathematically as a simple capacitor, based on a physical model in which a single layer of ions is adsorbed at the surface.

 Double layer - Wikipedia, the free encyclopedia
Double layers may be found anywhere that plasmas are found, from discharge tubes to space plasmas to the Birkeland currents supplying the Earth's aurora.
The charge distribution in a relativistic double layer is such that the "surface" charge density at the anode appears independent of the thickness of the double layer; in this respect, the double layer is similar to the charge distribution in a capacitor.
The double layer may also drift, usually in the direction of the emitted electron beam, and in this respect is a natural analogue of the smooth bore magnetron.

 Double Layer DVDs
Double Layer capable recorders will have the ability to record on the new Double Layer DVD recordable discs as well as traditional single layer DVD discs and CDs too.
Double Layer recordable discs contain two organic dye recording layers (termed L0 and L1, respectively) between dual polycarbonate bases and semi-reflective metal layers separated by a transparent spacing layer.
Because double layer recordable discs are basically one contiguous stream of block addresses, it’s not very difficult for software makers to make their disc mastering software compatible with Double Layer drives and media, as least where recording data is concerned.

 DriverHeaven Knowledgebase: DVD DL Technology
A Double Layer (DVD9), however, has two layers; both of which (like a single layer DVD) is sandwiched in between a disc.
Each layer has a metal reflector on top of it, to reflect the laser’s light, (this is how it is read).
The lower layer's reflector in a DVD DL is different from a single layer's reflector, in that it is semitransparent.

 DVD+RW Alliance - New dual-layer DVD+R technology developed by Philips in cooperation with MKM increases DVD recordable ...
Heating with a focused laser beam irreversibly modifies the physical and chemical structure of each layer such that the modified areas have different optical properties to those of their unmodified surroundings.
In addition, the transmission of the upper recording layer is greater than 50% to allow for read-out and recording of the lower recording layer.
This layer has high power sensitivity since the upper layer absorbs and reflects part of the incoming light.

 Electrokinetic Analzyers   (Site not responding. Last check: 2007-11-07)
This double layer surrounds all charged macromolecules and particles in solution and plays a role in several properties of significance in chemical analysis and processing including (but not limited to): precipitation, flocculation, electrophoresis, colloid stability, phase partitioning, and sorption.
The shear plane is assumed to be in the diffuse layer, close to the boundary between the fixed and the diffuse layers.
The Gouy-Chapman (G-C) theory, one of the first, assumes a) a flat, impenetratable surface, b) ions in solution are point charges, c) the surface charge and potential are uniformly distributed upon the surface, and d) the solvent properties (including dielectric constant) are independent of distance from the surface.

 SONY HEATS UP THE MARKET WITH NEW DOUBLE LAYER DVD BURNERS
Nearly doubling the storage capacity of current DVD recordable discs, the double layer DVD drives allow users to record up to four hours of high-quality MPEG-2 video or up to 8.5 GB of data, music and/or images on compatible DVD+R DL media.
Double layer recording also makes sense for businesses that deploy training information and video on DVD, and for independent filmmakers who want to create a prototype of their work on a double layer DVD videodisc before committing to mass replication.
Both layers can be accessed from the same side of the disc, so there is no need to turn the disc over during recording or playback.

 Dual-Layer (Double Layer) DVD Drives and Media > Introduction   (Site not responding. Last check: 2007-11-07)
It is interesting to note that the DL in DVD+R DL actually stands for Double Layer and not Dual-Layer, however the terms are often interchanged, and some media is advertised using both terms.
Inside the drive, a single laser is refocused when switching between layers, accounting for a slight delay when moving from the top to the bottom layer.
The metal reflector used by L0 is semi-transparent, enabling the refocused laser to write to the second layer (Layer 1; L1).

The true revolution thus lies in the switch to double layer.

 Sony debuts double-layer DVD drives | CNET News.com
Businesses could find the new devices useful for storing training information, while independent filmmakers could create prototypes of their work before committing to mass replication, Sony said.
Double-layer DVD discs are single-sided with two information layers that can be independently recorded to and read from, and both layers can be accessed from the same side of the disc.
"As the pioneer of dual format drives, we were the first to address confusion over competing DVD standards; with double layer, we will now satisfy the need for higher capacity," Robert DeMoulin, marketing manager for branded storage products at Sony Electronics, said in a statement.

Like most outboard models, its DVD-ripping speeds are sluggish, but its superior CD-burning performance, support for 4X dual-layer and 16X single-layer DVD recording, and the overall quality of its output make it an excellent choice.
The LaCie 16X d2 DVD+/-RW Double Layer external burner has many of the same strengths offered by earlier models: a tough, rack-mountable aluminum chassis, an auto-sensing dual FireWire/USB 2.0 interface, and a generous assortment of Roxio applications that together support most recent Windows and Mac operating systems.
