Exploring Vintage Optical Media: A Journey Through Japanese Archives

Exploring Vintage Optical Media: A Journey Through Japanese Archives

The quest for vintage technology can lead to unexpected discoveries. A recent exploration into the realm of optical media sourced from Japan has uncovered unique insights into CD-R and DVD technologies of the past. This journey reveals not only the evolution of these storage formats but also the nuances in manufacturing quality and regional market differences.

TDK UV Guard DVD+R: The Carbide Series

One notable find is the TDK UV Guard DVD+R, a product from a time when TDK manufactured its own discs. Unlike contemporary TDK media, which is often rebadged from other manufacturers, these discs feature a diamond-like carbon hard coating. This UV guard coating was designed to improve longevity by reducing PI error rates upon exposure. The packaging includes graphs illustrating the UV guard coating improves longevity.

Analysis reveals that the TDK UV Guard discs exhibit reduced transmission of wavelengths shorter than 500nm, indicating the UV-guard is effective. This feature would not interfere with ordinary operations, as DVD lasers operate around 650nm.
