TDK Electronics DVD+R47FCB100 4.7GM DVD+R media offers the widest compatibility with computer drives and home DVD players. Ideal for general purpose recording, a single TDK DVD+R has ample capacity for thousands of digital photos, up to six hours of videa and large mission-critical data files. Each DVD+R disc can be fully recorded once. As DVD recording speeds have increased, the importance of using name brand, quality media has become paramount. When a DVD+R is recorded at high sppeds, the fast RPM’s of the recording process require an advanced, ulrra-sensitive recording material capable of compensating for the abbreviated exposure to the drive laser. Specially formulated with a rapid phase-change recording layer, TDK DVD+R media maximizes the data transfer rate while minimizing the potential for errors. The discs have been thoroughly tested and verified to outperform other media brands, which may rely on slow-reacting, error-prone phase-change materials. TDK AVIST metallic alloys change between crystalline and amorphous states in response to the heat generated by a laser for phase-change recording. The differences in reflectivity exhibited by the alloy in its crystalline and amorphous states are read as data. TDK AVIST alloys are designed for the most precise laser response, resulting in perfect data marks and superior recording and playback performance.
