CD-ROM, CD-R, CD-RW, and DVD-ROM Drives) Are the Hardware Devices That Read Computer Data from Disks
A Brief History of CD/DVD The first disc that could be written and read by optical means (using light as a medium) was developed by James T. Russell. In the late 1960s, Russell created a system that recorded, stored, and played audio/video data using light rather than the traditional contact methods, which could easily damage the disks during playback. Russell developed a photosensitive disc that stored data as 1 micron-wide dots of light and dark. The dots were read by a laser, converted to an electrical signal, and then to audio or visual display for playback. Russell's own company manufactured the first disc player in 1980, although the technology never reached the marketplace until Philips and Sony developed the technology. In late 1982, Philips and Sony released the first of the compact disc (CD) formats, which they then called CD-DA (digital audio). In the years since, format has followed format as the original companies and other industry members developed more adaptations of the original specifications. Digital Versatile disc (DVD) had its beginning in 1994, when two formats, Super disc (SD) and Multimedia CD (MMCD) were introduced. Promoters of the competing technologies failed to reach an agreement on a single standard until 1996, when DVD was selected as a convergence format. DVD has, in the few years since, grown to include variations that do anything that CD does, and more efficiently. Standardization and compatibility issues aside, DVD is well-placed to supplant CD. Magnetic vs Optical Media Optical media are storage media that hold information in digital form and that are written and read by a laser; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers. -

EXP-26 Open Frame CD Player
EXP-26 Open Frame CD Player Topics: Diode Laser, Detection of Light, CD Control System, CD Structure, Computer Control The most widespread laser applications are unambiguously the optical data storage systems such as CD, DVD and nowadays Blue-Ray disc (BD). The CD was originally designed for storage and playing back music and was later extended to the CD-ROM for computer storage. Most optical drives operate on the principle of detecting changes in the intensity of light that is reflected by the media surface. The data information is printed as so-called pits onto the reflective surface of the media. The limitation of the storage capacity is the wave length of the laser light. Light of a shorter wavelength can be focused better thus allowing higher storage density. Within this course the data detection, the control loop for the reading laser head and other components of an optical drive will be demonstrated using the open frame CD player. The optical technique to read data remains the same regardless of whether a CD, a DVD or a BD is used. Examples of Investigations: Reading assembly: A laser beam of 780 nm wavelength is focused on the CD by means of lenses L1 and L2. The spot size on the reflective layer is about 0.6 µm. The light returning from the CD is reflected by the polarizing beam splitter cube (BC) due to the action of the quarter wave plate (QWP) and is imaged on the position sensitive sensor (PSD). Detection of pits: Once the laser beam hits a pit, a change in reflected light intensity occurs due to partial scattering and destructive interference between the incoming and outgoing laser beam. -

Measure the Distance Between Tracks of CD and DVD the Aim of Work
University of Technology Department Laser & Optoelectronics Engineering Laser Eng Branch Laser application Lab. Experiment (9) Measure the Distance Between Tracks of CD and DVD The aim of work: 1-measure the distance between tracks of CD and DVD. 2-study the different between the CD & DVD. Instruments:- Laser He-Ne, CD & DVD, screen, ruler, holders Theory:- The Compact Disc was invented by Sony and Philips in 1981 in order to serve as a high-quality compact audio storage device which allowed for direct access to digital sound tracks. It was officially launched in October 1982. In 1984, the Compact Disc's specifications were extended (with the publication of the Yellow Book) so that it could store digital data. A CD (Compact Disc) is an optical disc 12cm in diameter and 1.2mm thick (its thickness may vary from 1.1 to 1.5 mm) for storing digital information: up to 650 MB of computer data (equivalent to 300,000 typed pages) or 74 minutes of audio data. A circular hole 15mm in diameter is used to centre it on the CD player's surface. A CD is built from a plastic (polycarbonate) substrate and a fine, reflective metallic film (24-carat gold or a silver alloy). The reflective layer is then covered with an anti-UV acrylic finish, creating a protective surface for data. Finally, an additional layer may be added so that data can be written on the other side of the CD as well. The reflective layer contains tiny bumps. When the laser passes over the polycarbonate substrate, light is reflected off the reflective surface, but when the laser reaches a bump, that's what allows it to encode information. -
