Optics - Wikipedia, the free encyclopedia Some optical phenomena depend on the quantum nature of light and as such some areas of optics are also related to quantum mechanics. The "ray" in geometric optics is an abstract object which is perpendicular to the wavefronts of the actual optical waves. Optical science is a part of many related disciplines including electrical engineering, physics, psychology, medicine, and others. en.wikipedia.org /wiki/Optical   (808 words)

Optical disc - Wikipedia, the free encyclopedia The promotion of standardised optical storage is undertaken by the Optical Storage Technology Association (OSTA). The information on an optical disc is stored sequentially on a continuous spiral track from the innermost track to the outermost track. In computing, sound reproduction, and video, an optical disc is flat, circular, usually polycarbonate disc whereon data is stored. en.wikipedia.org /wiki/Optical_disc   (389 words)

Optical Data Storage Systems It is usually desired in optical recording to achieve the smallest laser beam spot possible, since the spot size is a measure of the bit size, which defines the areal density of the storage system. For the current optical storage systems, the depth of focus is about 1 mm. The first photographs were developed about 200 years ago and represented an analog optical storage, which has a limited application for information storage since it is difficult to interface analog data with machines, plus there is a continuous degradation of data at every step of reading and writing. www.usbyte.com /common/optical_data_storage_systems.htm   (699 words)

Chp 3: Overview of Optical Storage Systems Optical storage for very large storage devices employing interchangeable and recordable media in automatic "jukeboxes" is a market traditionally outside the range of magnetic disk drives but directly in competition with magnetic tapes. The storage capacity of an optical storage system is a direct function of spot size (minimum dimensions of a stored bit) and the geometrical dimensions of the media. Optical storage RandD typically concentrates on the following efforts: reducing spot size using lower-wavelength light sources; reducing the weight of optical pickup heads using holographic components; increasing rotation speeds using larger optical power lasers; improving the efficiency of error correction codes; and increasing the speed of the servo systems. www.wtec.org /loyola/opto/c3_s2.htm   (2177 words)

Imperial College London  “Optical data storage” is a general term covering all data storage techniques that use optical means to read, write and/or erase data. This corresponds to a storage density increase of 3.6 times which was achieved partly by decreasing the wavelength of the laser used to illuminate the disk and partly by increasing the numerical aperture of the lens employed. However, our current optical and electronic means are advanced enough to be able to compromise on this point and encode a single pit by more than a bit information. www.imperial.ac.uk /research/photonics/pt_group/peter_torok_research_topics_ODS.htm   (415 words)

Magneto-Optical Storage The MO systems include basic principles of both magnetic and optical storage systems: MO systems write magnetically (with thermal assist) and read optically. The thermal properties of the optical disk can be changed if the active magneto-optical layer is combined with thin optimizing layers, which may also improve the protection and signal-to-noise characteristics of the medium. There are two main media designs for rewritable optical systems: MO (magneto-optical) media and phase-change media (known as CD-RW). www.usbyte.com /common/MOsystems.htm   (908 words)

optical storage --  Encyclopædia Britannica For the permanent storage of data, one must turn to auxiliary storage, primarily magnetic and optical media such as tapes,... Current approaches to information storage and retrieval include high-density, high-speed, solid-state electronic memories, as well as slower (but generally more spacious) magnetic and optical discs (see computer memory). Even larger storage facilities have been created by using depleted oil or gas reservoirs near consumption centers or by the creation of artificial gas fields in aquifer layers. www.britannica.com /eb/article-9001488   (820 words)

OPTICAL STORAGE MARKET Another important reason is that optical storage manufacturing in Japan is backed up by a formidable optoelectronic industry that can manufacture CD related components at very low costs. Several reasons can account for this disparity, including the slow acceptance of optical storage products and short-term strategies of the U.S. industry in the eighties, the focused interest of the U.S. industry on magnetic hard disk drives, and the economic recession in the United States in the late eighties. The optical library segment had $514 million sales in 1996 and is only growing at 4.5% a year. www.wtec.org /loyola/hdmem/01_02.htm   (724 words)
