Precautions and maintenance (Continued)
Care and storage of the discs
• Keep the disc clean, or the image quality
of the audio and video output may
deteriorate.
• Clean the disc with a soft cloth.
Wipe the disc from the center out. For
dirt, clean the disc with a soft cloth
slightly moistened in water, then remove
the moisture with a soft, dry cloth. Do not
use solvents such as benzine, cleaners
intended for vinyl LPs or antistatic spray,
as they may cause a malfunction to the
disc.
• Do not expose the disc to direct sunlight
or leave it in a humid place.
• When you carry or store the disc, put it in
its case.
• When you want to write letters or marks,
etc. on a single-sided disc, write only on
the printed side using an oil-based marker
with a felt-tip, and do not touch the ink
until it dries. Do not heat the disc or use a
sharp-pointed tool, such as ball point pen.
Do not dry the surface by heating. You
cannot write, or mark, on double-sided
discs.
Your digital video camera recorder
incorporates both the AVCHD format and
the DVD format for the recording function.
What is the AVCHD format?
The AVCHD format is a high definition
digital video camera format used to record
an HD (high definition) signal of either the
1080i specification*
1
or the 720p
specification*
2
, using efficient data
compression coding technology. The
MPEG-4 AVC/H.264 format is adopted to
compress video data, and the Dolby Digital
or Linear PCM system is used to compress
audio data.
The MPEG-4 AVC/H.264 format is capable
of compressing images at higher efficiency
than that of the conventional image
compressing format. The MPEG-4 AVC/
H.264 format enables a high definition
(HD) video signal shot on a digital video
camera recorder to be recorded on 8 cm
DVD discs.
