Additional Information
Hard disk drive (page 3)
A hard disk drive is a whole mechanical system
that consists of disks and drive. Disks are flat,
circular, rigid plates coated with a thin magnetic
media. Magnetic heads record data on the rapidly
spinning disks, and this enables the speedy and
efficient reading and writing of data.
Interlace format (page 16)
Interlace format shows every other line of an
image as a single “field” and is the standard
method for displaying images on television. The
even number field shows the even numbered lines
of an image, and the odd numbered field shows the
odd numbered lines of an image.
MPEG Audio (page 92)
International standard coding system used to
compress audio digital signals authorized by ISO/
IEC. MPEG 2, used on DVDs, conforms to up to
7.1-channel surround.
Original (page 64)
Titles actually recorded on a DVD-RW (VR
mode). Erasing original titles frees up disc space.
Playlist (page 64)
Playback information created from the actual
recordings on a DVD-RW (VR mode). A Playlist
leaves the original titles as they are, and contains
only the information needed to control playback.
A Playlist title takes up very little disc space.
Progressive format (page 16)
Compared to the Interlace format that alternately
shows every other line of an image (field) to create
one frame, the Progressive format shows the entire
image at once as a single frame. This means that
while the Interlace format can show 25-30 frames/
50-60 fields in one second, the Progressive format
can show 50/60 frames in one second. The overall
picture quality increases and still images, text, and
horizontal lines appear sharper.

The longest section of a picture or music feature
on a DVD, movie, etc., in video software, or the
entire album in audio software.
Track (page 61)
