About DVD±R and DVD±RW discs

The DV-RA1000HD uses DVD±RW media for digital audio data recording and storage, and use DVD±R as media for the archive. DVD-RAM is not supported on this unit.

As with recordable DVD±RW media can have data erased, and the whole disc can be erased and reused a number of times.

NOTE

Though the unit has been tested with a wide vari- ety of commercial discs and media, you should be aware that some discs may contain manufacturing defects, etc. which make them unsuitable for use with the unit.

The packaging for rewritable DVD±RW media include the following logo:

Figure 1.7: DVD±RW discs

See “DVD±RW/HD playback & recording” on page 40 for more details regarding the use of DVD±RW media with the unit.

Certain brands of disc have been tested with the unit and are therefore listed as “supported.”

DVD±RW Ricoh,Verbatim,TDK,Philips,Sony 2x - 6x

DVD±R

Ricoh,Verbatim,TDK,Maxell,Sony 4x - 16x

The use of these discs is strongly recommended in order to achieve optimum results.

NOTE

•Discs not listed in the list above may not oper- ate properly on the DV-RA1000HD. If you insert an unsupported DVD disc in the tray, the unit will display a popup alarm message on the screen. If you plan to purchase discs in a bulk, insert a sample disc into the tray to make sure that the disc is supported prior to purchase. (See “Using a non-supported disc” on page 42.)

•The check screen enables you to check wheth- er a loaded DVD disc is supported by the DV-RA1000HD. (See “The check screen” on page 26.)

Note that dirt or scratches on DVD±RW media can cause deterioration of recording quality.

If such an error occurs during recording, recording is interrupted momentarily.

Errors during playback will cause silences to be momentarily inserted.

Repeated continuous errors will stop playback.

Rewriting limitations

Although the theoretical number of times that a DVD±RW disc can be re-written is 1,000, the actual number of rewrite operations possible on a disc when used in the DV-RA1000HD may be significantly less. This is not a limitation of the DV-RA1000HD. In actual practice in real-world environments, DVD±RW discs cannot be rewritten 1,000 times.

For this reason, to maintain data integrity, TASCAM strongly recommends the use of new DVD±RW discs for important recordings.

In addition, before and while editing files on the DV-RA1000HD, back up the recorded or edited files to another disc or personal computer (as WAV files). (See “Use with a computer” on page 59.)

NOTE

The number of times the current disc has been re- written can be viewed in the check screen. (See “The check screen” on page 26.)
