The CD was first introduced into the world by Phillips and the Sony corporation and was to replace the LP.It started rather badly butin 1995 there was a standard being set for the dvd
Cdrom have been around awhile,but as the world grows,so do technology.And we have ended up with a much bigger format called the DVD which stands for Digital Versatile Disk.
This is a high capacity cd size disc basically for multimedia applications.This high quality video and audio format may replace the VHS altogether.
The DVD started as the Digital Video Disc and some technicians may still refer the the disk with this name.DVD discs offer much higher capacity than CDs for high quality video,audio and software
The new DVD use the same format as the CDROM . Cdroms are great formats for recording data but the DVD is best for recording large applications like movies.And they are fast becoming the best choice for storage and computer backup.
The DVD for store up to 17.1 gigabytes of data whereas the cdrom can store up to 700 megabytes.Thats quiet a difference in storage space.
THE TYPES OF DVD DRIVES
Early DVD drives were all dvd-rw compatible made by the dvd forum,a group of manufacturers that started the dvd format together.
The first DVD+RW drives had no capability to write -once DVD media.However,in 2002 Verbatim became the first media maker to offer DVD+RW technology in both the ReWritable and Write-once formats,alright already.
Around In October 2003, Philips and Mitsubishi displayed the new dual-layer DVD recordable technology. The new technology virtually doubles data storage capacity on DVD+R recordable discs from 4.7GB to 8.5GB, while remaining compatible with existing DVD Video players and DVD-ROM drives.
DVD Multi-compliant drives, provide read/write support for all DVD recordable DVD specifications with theDVD-RAM, DVD-R and DVD-RW as well as read/write support for CD-R and CD-RW media.
When the dvd format started there were different versions and there was no guarantee that your recording from one dvd writer would play on another player.
To add to the versions,the DVD-RAM lets you erase specific files and add new ones.You could also write to the dvd up to 1000,000 times became any data degration may occur.
The dvd-rw will only allow you to write to the disk just 1,000 times before data degradation.And the new DVD-Audio format was developed for music and other audio files.
Talk about mass confusion concerning the dvd.While you may not be concerned at all about the technical side of the dvd,it may be to your advantage to learn the basics.Be sure your dvd player and writer will support all format of the dvd.
FEATURES OF THE DIGITAL VERSATILE DISC
The DVD has the same physical dimemsions as the compact disc but is made slightly different.Most DVD hardware will play audio CDs and CDROMs
All formats of the dvd use a common file system named UDF.The DVD come in both recordable and re-writable versions.Let's briefly mention the different formats of the dvd.
The DVD ROM has the read-only format supporting discs with capacities of from 4.7GB to 17GB and access rates of 600 KBps to 1.3 MBps. Backward- compatible with CD-ROMs.
DVD Video is used for displaying full-length digital movies. DVD-Video players televisions like videocassette players. The Digital-Video format includes a Content Scrambling System (CSS) to prevent users from copying discs.
The DVD audio store audio similar to the CD-Audio format. DVD-Audio is facing stiff competition from a number of other high fidelity audio standards.
The DVD Recordable Disc use the write-once DVD format. DVD-R discs are the DVD counterpart to CD-R discs.
The DVDRAM use a rewritable compact disc format that provides much greater data storage than today's CD-RW systems. The caddy-mounted discs will initially provide 2.6GB per side on single or double-sided discs.
DVD is the new generation of optical disc storage technology. This is bigger and faster than the CD. DVD aims to encompass home entertainment, computers, and business information with a single digital format.
It has replaced laserdisc, is well on the way to replacing videotape and video game cartridges, and could eventually replace audio CD and CD-ROM. And now the DVD has widespread support from all major electronics companies.
