The Current State of 
Recordable DVD Media Formats
Recordable DVD Media Formats
CD-R and -RW continue to be the most widely used 
removable storage technology because of the 
extremely low cost of drives, players and media.   
However, with prices for DVD hardware and media 
dropping, the DVD recordable formats are rapidly 
gaining acceptance for use in document, video, 
audio and personal/professional storage.     
The prime selling points of DVD are its inherent 
reliability and massive data storage capabilities--
ultimately up to 9.4GB of removable storage with a 
double-sided disc. 
According to Wolfgang Schlichting, IDC's 
Research Manager, Removable Storage, 2002 will 
be the year when many consumers will discover 
the benefits of DVD recording. IDC projects that 
worldwide DVD media sales will climb from 50 
million discs in 2002 to nearly 150 million in 2004.
There are basically two markets for recordable 
DVD: computer storage and A/V recording.  While 
all of the format developers have focused on 
providing a single format that will work for both 
video and computer applications, each DVD 
format has its strengths and weaknesses

Applications
All DVD media formats share common parameters 
for use in a wide range of personal and 
professional applications. The discs look very 
similar; however, they do not all work in every DVD 
drive, DVD-Video player or DVD recorder.

While the DVD formats have important technical 
differences, the charts below have been developed 
to help content developers and users determine 
which media is best for them.
General Format Discussion
DVD-R, a recordable version of DVD-ROM - The 
DVD Forum has developed specifications for two 
write-once DVD-R categories - Authoring and 
General use.   Although both types of DVD-R media 
can be read by nearly all DVD drives and players, 
technical differences make it impossible to write to 
DVD-R Authoring media using a consumer DVD-R 
General system and vice versa. DVD-R General 
recorders use a 650 nm 
recording laser 
wavelength while DVD-R Authoring use a 635 nm 
laser.   In addition, the General Use media contains 
content protection technology to prevent users 
from making bit-for-bit copies of CSS- encrypted 
entertainment titles.
