6 − DVD±RW/HD playback & recording

The DV-RA1000HD features high-resolution recording using DVD±RW discs or HD. The format of this high- resolution recording is different from that for recording a standard DVD audio, SACD, or CD-DA disc.

The recording process creates an archive of audio files which you can edit using a DV-RA1000HD. Also, these files can be subsequently transferred to external devices or personal computer such as a digital audio worksta-

tion (DAW) for later sound processing and pre-master- ing.

NOTE

On the DV-RA1000HD, you can use DVD±RW discs and the HDD for real-time recording. You can use DVD±R discs only in copy mode to duplicate data.

Organization of projects and files

On the DV-RA1000HD, a project consists of up to 99 audio files—the same number as the maximum number of tracks on a Red Book CD-DA.

When you format a brand new DVD±RW disc with the DV-RA1000HD, a new project is automatically added to the disc. (See “Using a new DVD±RW disc” on page 41.) The DV-RA1000HD internal HD already includes one default project (44.1kHz, 24-bit) at the time of ship- ment.

In a project, all the files must be the same sampling fre- quency (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 dif- ferent sampling frequencies.

As well as the audio files, a project also contains the following information:

•Mark data

•Text associated with the project other than the file names

•A play list showing the running order

Writing the UDFMI

In order for the DV-RA1000HD to read the information on a DVD±RW disc, control information referred as UDFMI (UDF Management Information) must be writ- ten to the disc.

Although the DV-RA1000HD writes this control infor- mation at key events, such as when the disc is ejected, when the unit is shut down (see “Shut down” on page 19), or when ODD/HDD mode is switched, unexpected power loss may cause a disc to appear unreadable.

To write the UDFMI manually:

1While the transport section is stopped, select the DISC sub-menu from the main menu.

2Highlight the SAVE UDFMI item and press ENTER.

3A 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 de- fault as a short cut using function key F5. (See “Short cuts for screen access” on page 25.)

CAUTION

There is a limit to the number of times that DVD±RW media used by the DV-RA1000HD 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, environmen- tal factors, etc. introduce an element of unpredict- ability. We therefore recommend that wherever possible, you use new media for important record- ing projects, to prevent the possibility of data loss caused by media errors.

Viewing the number of rewriting times

The number of times the current disc has been rewrit- ten can be viewed in the check screen. Select CHECK in the system setup menu to display the check screen.

Then, press the F3 (MEDIUM) key to view the number. (See “The check screen” on page 26.)
