1.1General and Technology

The Digital Versatile Disc (DVD) is the logical successor of the Compact Disc (CD). Moreover, due to the high data storage capacity this disc has also become the data medium for the film-industry. It has been deve- loped throughout the nineties, but is only now coming into prominence. In spite of the DVD having a much higher data storage capacity (between 7 and 24 times) than the CD, both look the same. The main difference between DVD and CD consists of the shorter wave- length of the laser light, which reads the information.

The picture above clearly shows the difference in the structure of CDs (left) and DVDs (right). (Pictures were taken by microscope)

Based on the well proven experience in the world of CD Production, Sony DADC Austria AG has played a very important role in the field of the development for the right process of DVD-production.

Because of the fine structure the DVD is able to store huge amount of data, much more than CDs. Moreover, the DVD can also be produced with up to four layers (shown on the following pictures).

There are four main sizes of DVDs:

•DVD 5 (4,7 GigaByte)

•DVD 9 (8,5 GigaByte)

•DVD 10 (9,4 GigaByte)

•DVD 18 (17,1 GigaByte)

From the production point of view there is a big diffe- rence between CD and DVD due to the multi-layer tech- nology. DVDs consist of two polycarbonate discs (each 0,6 mm thick), which are bonded together. This adhe- ring process is one of the critical production steps since the laser has to ”read through” the adhesive. Sony DADC Austria AG have developed their own process throughout years of trial and step-by-step improvement to its final high reliable and very fast production route.

The DVD 5 is big enough to accommodate 130 min of movie with one audio stream. To add special features like interviews of actors, special scenes such as ”The Making Of” or more than one audio stream, it is recommended to use a DVD 9.

The DVD 9 is big enough to store one film of about 130 min playtime with up to eight languages and an addi- tional 35 mm approximately of bonus material. Alternatively, one film with one language, but a playtime of about 5 hours can be stored.

However if you have generated your content Sony DADC Austria AG will be happy to find the right DVD for you.

For capacities smaller than 4,7 GigaByte or some spe- cial promotion Sony DADC Austria AG is pleased to offer the MiniDVD, which is a DVD with a diameter of 8 cm. The MiniDVD can accommodate up to 1,46 GigaByte on a single layer or up to 2,66 GigaByte using the dual layer technology.

DVD Rom/DVD Video specifications

Sony DVD-ROM/DVD Video technology has played a significant role in the evolution of home entertainment and data storage. Since its introduction in the late 1990s, this versatile format has enabled users to enjoy high-quality video and audio, making it a standard for movie distribution and video playback.

One of the main features of Sony DVD-ROM is its substantial storage capacity. A single-layer DVD can hold approximately 4.7 GB of data, which is significantly more than a standard CD, while dual-layer DVDs can store up to 8.5 GB. This increased capacity allows for higher-quality video content, including full-length movies, with multiple audio tracks and subtitles included.

In terms of video quality, DVD Video supports a resolution of up to 720x480 pixels, providing a clear and vibrant viewing experience. The technology utilizes advanced compression techniques, such as MPEG-2, to efficiently encode video files while maintaining high fidelity. This level of quality, coupled with the ability to offer surround sound formats like Dolby Digital and DTS, makes DVD a preferred choice for cinema-quality home viewing.

Another significant characteristic of Sony DVD technology is its robustness and durability. Compared to other media formats, DVDs are less susceptible to scratches and degradation, ensuring a longer lifespan for physical media. They also employ error correction technologies that help maintain data integrity, providing a reliable storage medium for both movies and computer files.

One of the innovative features of Sony's DVD technology is the menu and navigation system. Users can easily access different scenes, bonus content, and settings through an interactive graphic interface. This enhances the overall viewing experience, offering flexibility to skip chapters or access special features without hassle.

Sony has also embraced the evolution of DVD technology with the introduction of DVD-Audio and DVD-RAM formats. DVD-Audio provides superior audio quality, supporting multi-channel sound and higher sampling rates, catering to audiophiles. Additionally, DVD-RAM offers rewritable disk capabilities, making it suitable for data storage solutions that require frequent modifications.

In conclusion, Sony DVD-ROM/DVD Video technology has established itself as a cornerstone in digital media. With impressive storage capacity, superior video and audio quality, robust durability, and user-friendly navigation, it continues to influence the landscape of home entertainment. As technology progresses, understanding these characteristics becomes essential for consumers and content creators alike, ensuring they can make informed choices in a shifting digital era.
