Incredible progress in magnetic memories (hard disk…), optical formats (CD, DVD…), and semiconductor solid state memories (USB keys…) has been enabled by innovation from intensive R&D in Europe, US and Japan, and fostered innovation in many other areas of technology. The market opportunities opened by these innovations have clearly addressed many fundamental expectations of citizens, and the critical needs of the industry. As a result, the progress of mass storage technologies is intimately associated with the development or the creation of key areas of the modern economies, such as telecommunications, leisure (music, films, games…), banking, improving work productivity and work accessibility (easiness), transportation… The data mass storage technologies are fundamental building blocks of ICT. They will increase the quality of life for the citizens in areas reaching from education to entertainment, from working environment to health services. They also save resources, and strongly contribute to further economic growth, securing employment. Currently around 70,000 people in Europe are directly and 300,000 indirectly involved production or research related to mass data storage. The dynamic knowledge- based objectives of the Lisbon process will find a new impetus through new technology take-up in the area of mass data storage technologies World-wide, mass data storage technologies are today a market in the 40 – 50 Billion of Euro range. Europe has been and is a global driver in storage research and innovation through a strong supply industry. However, it seems that the EU is now investing proportionately less than its main competitors into R&D. To preserve the existence of EU based world-class production facilities in mass data storage technologies, and to secure competitive position in the markets linked to emerging technologies for mass data storage, it is crucial that a favourable environment for innovation and investment is created. This is especially true for small and medium sized enterprises (SMEs), and to

  • 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.

  • DAT330 – Principles of Digital Audio Cogswell Polytechnical College Spring 2009
    DAT330 – Principles of Digital Audio Cogswell Polytechnical College Spring 2009 Week 6 – Class Notes Optical Disc Media: CD and DVD Optical Disc Media Design of Optical Media Most optical storage systems store data across the surface of a flat disc. This allows random access of data, as well as ease of manufacturing replication. Because the data is written and read via optical means, there is no physical contact between the media and the pickup. This ensures long media and pickup life and minimizes damage through head crashes or other failures. In addition, a protective layer can be used to protect the data from damages or contamination. Also, multiple data layers can be places within one substrate. Nonetheless, stored data must undergo both modulation and error correction. Data can be stored either along a spiral or concentric tracks. Most optical disc pickups shine a laser on the medium, and the reflected light is detected by a sensor and decoded to recover the carried data. The medium must have two states so that the change between them varies with the reflected light. Data can be represented as a phase change, polarization change, or change in the intensity of reflected light. The resulting variations picked up from the media can be converted into a varying electrical signal for data recovery. Laser beams, having a short wavelength, allow for high information data density and a high SNR needed for a high bit rate. Optical media must be supported by a sophisticated servo system to provide positioning, tracking, focusing of the pickup, and accurate rotation.
