Verbatim has always been at the forefront of technological innovation. We are able to maintain our leadership and market the very latest products and technologies due to the extensive research and development that is undertaken by our parent company Mitsubishi Kagaku Media in Japan.
We pride ourselves on our 'Core Technologies'.
The AZO recording layer not only withstands the extremely high laser and rotation speeds of the new drives, it also maximises their performance. Verbatim has paid particular attention to the durability and light fastness of AZO; tests show that it is more stable than most recording dyes and the least affected by ultraviolet light.
The recording dye is critical to CD-R performance; its molecular structure must be designed to absorb the typical wavelength of a CD-R drive laser, which is around 780nm. The peak absorption wavelength needs to be optimised so that the disk is compatible with a wide range of recording speeds.
If the peak is too short, disk sensitivity is reduced, which causes high-speed recording problems; but if the wavelength peak is too long, this reduces the reflectivity of the recording layer and can creates read errors in many drives.
AZO offers high sensitivity for reliable high-speed recording and high reflectivity to eliminate read errors. The thinness of the recording layer is also critical. The thinner the layer, the higher its sensitivity and power margin, and the better its high-speed recording capabilities.
Some DVD's are handled extensively, for example 8cm DVD's are constantly placed in and out of the camcorder in external environments. To protect from potential damage, Verbatim 8cm DVD's benefit from a 'Hard Coat' protective layer. This layer protects from fingerprints, dust, scratches, static and water. Testing is believing!
Data CD's need to be as robust as possible as they are often used during travel and may not always be stored in jewel cases or protective sleeve. As a result, scratches can occur on the surface of the disc, which means reduction in quality and in many cases, loss of data.
Make sure your music and data are 'Crystal' Clear.
Used with Verbatim BD-R media.
BD-R LTH Type
BD-R LTH Type is another type of BD-R. The recording layer and manufacturing process is different:
- The first type of BD-R was made of inorganic material and the signal changes polarity from High to Low (HTL).
- AZO BD-R is made of organic material and the signal changes polarity from Low to High (LTH).
- The key process in creating LTH BD-R discs is spin-coating, which is more efficient than sputtering in a vacuum system.
- More than 80% of the waste material in an LTH BD-R disc manufacturing process is recycled.
- Applies to DVD-RAM products
- This media allows recording of 'Copy Once' broadcast programmes.
- CPRM = Copy Protection for Removable Media
