DVD Specifications for DVD-RAM Disc for Version 2.0, Version 2.1
or Version 2.2
Hitachi Maxell Ltd.
■
This drive cannot use discs that allow writing faster than 8 speed (DVD-
R, DVD+R), 4 speed (DVD-RW, DVD+RW), 5 speed (DVD-RAM), 2.4
speed (DVD+R DL, Double Layer supported model only), 2 speed
(DVD-R DL, Dual Layer supported model only).
■
2.6GB and 5.2GB DVD-RAM media cannot be read from or written to.
■
DISC created in DVD-R DL format4 (Layer Jump Recording) cannot be
read.
■
If the disc is poor in quality, dirty or damaged, writing or rewriting errors
may occur. Be careful to check the disc for dirt or damage before you
use it.
■
The actual number of rewrites to CD-RW, DVD-RW, DVD+RW or DVD-
RAM is affected by the quality of the disc and the way it is used.
■
There are two types of DVD-R discs: authoring and general use discs.
Do not use authoring discs. Only general use discs can be written to by
a computer drive.
■
You can use DVD-RAM discs that can be removed from a cartridge and
DVD-RAM discs designed without a cartridge.
■
Other DVD-ROM drives for computers or other DVD players may not be
able to read DVD-R/-R DL/-RW or DVD+R/+R DL/+RW discs.
■
Data written to a CD-R/DVD-R/-R DL/DVD+R/+R DL disc cannot be
deleted either in whole or in part.
■
Data deleted (erased) from a CD-RW, DVD-RW, DVD+RW and DVD-
RAM disc cannot be recovered. Check the content of the disc carefully
before you delete it. If multiple drives that can write data to discs are
connected, be careful not to delete data from the wrong drive.
■
In writing to a DVD-R/-R DL/-RW, DVD+R/+R DL/+RW or DVD-RAM
disc, some disc space is required for file management, so you may not
be able to write the full capacity of the disc.
■
Since the disc is based on the DVD standard, it might be filled with
dummy data if the written data is less than about 1 GB. Even if you write
only a small amount of data, it might take time to fill in the dummy data.
■
DVD-RAM formatted by FAT32 cannot be read in Windows 2000
without DVD-RAM Driver Software.
■
When multiple drives that can write data to discs are connected, be
careful not to write to the wrong drive.
