Quality
"JVC Media?"
The Japanese-quality media is able to write, read and preserve the data in a high-quality and reliable fashion. Using Japanese-quality media ensures a consistent, reliable experience with reading, playing, and preserving your data
While the occurrence of these types of issues is a supposedly impermissible for a manufacturer of standardized products such as CDs and DVDs, surprisingly, many users have experienced trouble where they suspect the disc as the cause (Figure 1).
Have you experienced any problems on using DVD recordable media, such as failure in writing and/or reading, etc...? （n=900/survey in Germany, UK and France/multiple answers）
Studies show that 62％ of consumers have had some problems with media.
Features of JVC Products
JVC designs and manufactures optical media with these three features in mind for our customers:
- Feature01 Data can be properly written and read
- Feature02 Important data is protected reliably, even over time
- Feature03 Variations in product quality are kept to a minimum
To achieve these features, JVC Advanced Media is thoroughly focused on the in-house design of materials, equipment, and recording technologies, and integrated production in Japan.
To properly write and read optical discs, we strive to achieve optimal compatibility with each drive manufacturer, to design a disc that is not subject to thermal focus errors in the writing process, and develop materials that react properly to lasers, as well as the in-house development of firmware technologies that offer the most effective write strategies to the disc.
Thermal interference occurs, making the border between each pit ambiguous. This leads to inserted signals being falsely recognized as a different pit.
The component technologies for ensuring recording and playback compatibility
are optical design and thermal design.
First, the required optical design is developed, and then the thermal recording
design that will make this a reality is carried out. Design begins with optical
simulations to ensure that the generated pits are of the ideal pit shape for actual
writing and reading.
Next, based on accumulated technology that spans 20 years, thermal
simulations of effects due to the dye material's endothermic and exothermic
properties, optical absorption efficiency, pit shape, film interface and layer
composition are run by computer, achieving an optimal disc design consistent
with the optical simulation.
The results of errors measured in recording to a JVC DVD-R disc with various drives and recorders.
JVC Optical Media consistently tests well within the ideal error specification across all major brands of recording device.
To ensure that recording characteristics stay the same over time, the purity of materials used in the disc and moulding conditions during manufacturing are monitored and strictly controlled. By designing our own materials and equipment, from the development stages onward, JVC has a complete in-house understanding of what it takes to enable manufacturing of the best possible product.
- Material(Molecular)Design
- In-house Design of Equipment
- Strict Materials Control
To prevent human error and other problems, JVC has advanced equipment automation as far as possible to produce products of the highest stablility and quality.
[Point 1]
Distribution stays tightly focused from the center value. From this, we can see that
there is little error variation in mass-produced products.
[Point 2]
Mass production has been achieved properly, even in terms of our own internal
standards that are far more stringent than industry specifications.
Materials, equipment and recording technologies are all designed and developed in-house, and technology development is ongoing. This quality can only be achieved through JVC's integrated development and manufacturing at its plants in Japan.
