❖In writing to a DVD-R/-RW disc, some disc space is required for file manage-
ment, so you may not be able to write the full capacity of the disc.
❖❖
❖❖
❖Since the disc is based on the DVD standard, it will 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 will take time to fill in the dummy data.

❖Two types of DVD-R/-RW/-RAM discs are on the market: data and video. Use
a video disc to store video data. You can use video discs on a DVD recorder as

DVD recorder.
