5 – DVD playback & recording
When performing high-resolution recording using
DVD media with the DV-RA1000, it is important to
remember that you are not recording a standard audio
disc.
The recording process creates an archive of audio
files which can be edited and played back using a
DV-RA1000. They can be subsequently retrieved or
transferred to another unit such as a digital audio
workstation for later processing and pre-mastering.
NOTE
The DV-RA1000 uses DVD+RW media for high-resolu-
tion recording. You cannot use DVD-R, DVD-RW or
DVD-RAM media with the DV-RA1000.
Organization of projects and files
On the DV-RA1000, a project consists of up to 99
audio files—the same number as the maximum num-
ber of tracks on a Red Book CD-DA.
In a project, all the files must be the same sampling
frequency (or all in DSD format). This is determined
when the project is set up.
You can have different projects on the same disc (up
to 99 of them, in fact), and different projects can have
different sampling frequencies and word lengths.
As well as the audio files, a project also contains the
following information:
• The setup for the effects
• Mark data
• Text associated with the project other than the file
names
• A playlist showing the running order
• User settings for the DV-RA1000
Important note on the file system
In order for the DV-RA1000 to read the information
on a disc, control information referred as UDFMI
(UDF Management Information) must be written to
the disc.
Although the DV-RA1000 writes this control infor-
mation at key events, such as when the disc is
ejected, or the unit is shut down (see “Shut down” on
page 32), unexpected power loss may cause a disc to
appear unreadable.
To write the UDFMI manually:
1 From the stopped state, press
MENU
and use
the wheel and
ENTER
to select the
DVD
menu.
From there, select the DISC sub-menu.
2
Highlight the SAVE UDFMI item and press
ENTER
.
3 A popup asks you if you are sure. Press
ENTER
to continue, and a progress bar shows
the progress of the operation.
Press CANCEL to cancel the operation.
TIP
This SAVE UDFMI function is also installed by default as
a short cut using function key
F5
(see “Short cuts” on
page 18).
CAUTION
There is a limit to the number of times that DVD+RW
media used by the DV-RA1000 can be written. This also
applies to the UDFMI. It is impossible to provide definite
guidelines on the number of times this is possible, but
the type of media, environmental factors, etc. introduce
an element of unpredictability. We therefore recom-
mend that wherever possible, you use new media for
important recording projects, to prevent the possibility
of data loss caused by media errors.
