CD- RW (Compact Disc- Re. Writable) is a digitaloptical discstorage format. A CD- RW disc is a compact disc that can be written, read arbitrarily many times, erased, and written again. The technology was introduced in 1. CD- RW discs (CD- RWs) require readers that have more sensitive laser optics than are required to read plain CDs. Consequently, CD- RWs cannot be read in many CD readers built prior to the introduction of CD- RW. CD- ROM drives that bear a . Different blanking methods can be used, including . Fast blanking is much quicker, and is usually sufficient to allow rewriting the disc. Full blanking removes traces of the former data, often for confidentiality reasons. It may be possible to recover data from full- blanked CD- RWs with specialty data recovery equipment. CD- RWs are usually written and erased in their totality, and not with repeated small scale changes, so normally wear leveling is not an issue. Their ideal usage field is in the creation of test discs, temporary short or mid- term backups, and in general, where an intermediate solution between online and offline storage schemes is required. Prior to the introduction of the CD- RW technology, a standard for magneto- optical recordable and erasable CDs called CD- MO was introduced in 1. Orange Book, part 1, and was basically a CD with a magneto- optical recording layer. How do I delete an audio CD-RW?? Location : Brooklyn, NY. Download free erase dvd rw. ONLY ONE DVD RW drive (CD RW drive) The program has One. The CD- MO standard also allowed for an optional non- erasable zone on the disc, which could be read by normal CD- ROM reader units. Data recording (and erasing) was achieved by heating the magneto- optical layer's material (e. Dy. Fe. Co or less often Tb. Fe. Co or Gd. Fe. Co) up to its Curie point thus erasing all previous data and then using a magnetic field to write the new data, in a manner essentially identical to Sony's Mini. Disc and other magneto- optical formats. Reading of the discs relied on the Kerr effect. This was also the first major flaw of this format: it could be read in only special drives and was physically incompatible with non magneto- optical enabled drives, in a much more radical way than the later CD- RWs. The format was never released commercially. A similar situation was also present for early CD- R media, which suffered from either physical or logical incompatibilities. Since the CD- MO was otherwise physically identical to . There were (and are) however some magneto- optical drives and media with the same form factor that don't have this limitation. Unlike modern CD- RWs, CD- MO allowed for hybrid discs containing both an unmodifiable, pressed section, readable in standard drives, and a writable MO section. This early introduction along with the lack of standards for disc recording software, file systems and formats, physical incompatibility as well as the introduction of the more economical CD- R discs essentially caused the format to be abandoned before commercialization. Other kinds of magneto- optical media, unbound by the limitations of the typical CD- ROM filesystems, took the place intended for CD- MO. Mechanism of action. The CD- RW technology is based on phase change technology, so the degree of reflection reached is only 1. The reflective layer is, however, a silver- indium- antimony- tellurium (Ag. In. Sb. Te) alloy, which has in its original state, a polycrystalline structure and reflective properties. When writing the laser beam uses its maximum power (8 - 1. W). This causes liquefaction of the material. In this state, the alloy loses its polycrystalline structure, assumes an amorphous state and lose its reflectivity. The lost reflectivity serves the same function as bumps on a manufactured CDs and the opaque spots on a CD- R which will be read as a . To erase the disc, the write beam heats the amorphous regions with low power to about 2. The alloy is not melted, but returns to the polycrystalline state and is thus again reflective.
