Writeable DVD

1. Formats

Writable DVD - Page 1

Do you feel that your CDR/W storage capabilities are small ? Do you want more space ?..Then Writable DVD is the solution for you..Yes ?..Not so True..All companies that involved into DVD consorium have not decided at a common standard. Lets see which techonologies are running right now..

Today is avaiable :

- DVD-Recordable (DVD-R): DVD is the de-facto standard from DVD Forum. It can record only 1 time so it will unlikely used for home recording.

- DVD-Rewritable (DVD-RW): Its a special format of DVD-Video and uses a special disc stucture and substrata which can be written up to 1000 times.

- DVD Random Access Memory (DVD-RAM): This standard is backed up from Matsushita. It uses a caddy and has a different disc structure that makes it more suitable to high-speed computer access than for video recording.

- DVD-ReWritable (DVD+RW): It uses a simular 4.7GB phase change land-and groove disc as DVD-RW but it's incompartible with DVD-RW.

Other upcoming formats (outsiders..):

- AS-MO (formerly MO7) holds 5 to 6 GB.
-NEC's MMVF (Multimedia Video Format) is completely incompartible with any other DVD format and it holds 5.2 GB.

Both are expected to read DVD-ROM but not DVD-RAM or first-generation DVD+RW. MMVF is similar to DVD-RW and DVD+RW, using two bonded 0.6mm phase-change substrates, land and groove recording, and a 640nm laser.

- Terastor is and 20GB optical format. It is incompartible with DVD thanks to different disc structure format.
