The design of DVD reflects the widespread success of CD-ROM as a data carrier for computer programs, databases, multimedia software and video games. As computer-processing power continues to increase, the need for higher capacity media is becoming increasingly apparent. And expanding markets for high-resolution graphics and full motion video continue to push the limits of existing storage media. In this environment, DVD-ROM will help satisfy the constant demand for the increased storage. With all the advantages, DVD-ROM is poised to become the undisputed leader in next-generation optical media for computers, multimedia and video games. DVD is poised to spark new opportunities and creative applications that we can only imagine today. High capacity, Recordable optical disk technology took a big step last month when the DVD Consortium announced it had finalized the DVD-RAM and DVD-R formats. The new systems offer up to 5.2 GB of data storage. The DVD-RAM standard will utilize the wobble-land-groove recording method to enable the users to store 2.6 GB on a single sided disk and 5.2GB on a double-sided disk. The wobble-land-groove method combines the land-groove recording method, in which data is recorded in grooves in the disk and lands, the areas between the grooves, and the wobble method, in which the disk tracks are not perfectly circular but move slightly from left to right as they run round the disk. The DVD-R system, which is write-once version for computer use, will have the capacity to store 3.95 GB on a single-sided disk, and 7.9 GB on a double-sided disk. The difference in format is due to a different recording method, where in a laser records to an organic dye on the disk. Besides the 12-cm version, DVD-R will also have a smaller 8-cm cousin. The leader in the world who is making the DVDROM drives are Mass Data Delivery and Storage:
Every day there are more ideas for using mass storage in a small, portable medium.
For example, content that currently fills several CDs would fit on one DVD.
Write able DVD, as a data backup medium, provides far shorter seek and retrieval times than magnetic tape.
Instead of shipping multiple units, software companies could encrypt multiple titles, distribute them all one DVD, and charge consumers for decryption keys.
Single standard for the World:
DVD-RAM and DVD-R Standards:
Manufacturer:
DVD consortium, formed to create a single, unified standard for the emerging DVD format, consists of 11 electronic companies.
These companies are Hewlett-Packard, JVC, Kodak, Matsushita, Mitsubishi, Philips, Pioneer, Sony, Thomson, Time Warner, and Toshiba.
The format enjoys the enthusiastic support of the world's major electronics & computer companies. As a movie playback format, it meets the specific and detailed requests of the motion picture Industry's Studio Advisory Committee.
As a computer ROM format, it meets the specifications of the computer Industry's Technical Working Group.
No other product has enjoyed such broad international support across so many industries prior to launch
