Recording times and track lengths

DVD±RW discs recording

The total time recordable on a DVD±RW single-layer disc depends on the sampling frequency.

In addition, the maximum file size is fixed at 2GB. This means that the maximum recording time per track also varies according to the sampling frequency.

All audio files must be at least four seconds in length.

Sampling		Recording	Disc time	Maximum
				track length
frequency		type	(minutes)	(minutes)
44.1	kHz	PCM	290	135
48	kHz	PCM	266	124
88.2 kHz		PCM	144	67
96	kHz	PCM	133	62
176.4 kHz		PCM	70	33
192	kHz	PCM	66	30
2.8224 MHz		DSD	107	50

HD recording

The total time recordable on the HD is significantly longer than the time recordable on a DVD±RW disc. However, the maximum file length on the HD is the same as for a DVD±RW disc. There is a limit to the recording time for each project.

All audio files on the HD must be at least four seconds in length.

The following recording times are estimates. You can- not extend the recording time beyond the maximum time specified for each project.

Sampling	Recording	Maximum project length	Maximum recordable time on the HD
frequency	type		(60 GB)
44.1 kHz	PCM	811 minutes (13.5 hours)	3779 minutes (62.9 hours)
48.0 kHz	PCM	745 minutes (12.4 hours)	3472 minutes (57.8 hours)
88.2 kHz	PCM	405 minutes (6.7 hours)	1889 minutes (31.4 hours)
96.0 kHz	PCM	372 minutes (6.2 hours)	1736 minutes (28.9 hours)
176.4 kHz	PCM	202 minutes (3.3 hours)	944 minutes (15.7 hours)
192.0 kHz	PCM	186 minutes (3.1 hours)	868 minutes (14.4 hours)
2.8224 MHz	DSD	811 minutes (13.5 hours)	1417 minutes (23.6 hours)

Using a new DVD±RW disc

When you insert a new DVD±RW disc into the tray and close it, the DV-RA1000HD displays a popup screen. Press the ENTER key to display the format screen shown below. Follow the steps below to format the disc:

NOTE

You cannot use a DVD±R disc which is not re- corded any project. If you insert a DVD±R disc into the tray, the DV-RA1000HD displays a message

“UNUSABLE DISC.”

1Press the F1 or F2 key (cursor) to highlight

FORMAT.

2Rotate the JOG/DATA dial to select QUICK or

FULL.

Quick format

This formatting writes a project file and other neces- sary data, then places the DV-RA1000HD in record ready mode in a few minutes.

If you insert a brand new disc, the DV-RA1000HD will work in the background when the unit is not recording or playing to format an unrecorded area on the disc.
