Notes On Discs; Notes On Mp3 Files - Sony DVX-11A Mode D'emploi

Notes on discs

• To keep the disc clean, do not touch the surface.
Handle the disc by its edge.
• Keep your discs in their cases or disc
magazines when not in use.
Do not subject the discs to heat/high
temperature. Avoid leaving them in parked cars
or on dashboards/rear trays.
• Do not attach labels, or use discs with sticky
ink/residue. Such discs may stop spinning
when used, causing a malfunction, or may ruin
the disc.
• Do not use any discs with labels or stickers
attached as this may cause inability to read data
correctly (e.g., playback skipping, or no
playback) due to heat shrinking of a sticker or
label causing a disc to warp.
• Discs with non-standard shapes (e.g., heart,
square, star) cannot be played on this unit.
Attempting to do so may damage the unit. Do
not use such discs.
• Before playing, clean discs with a
commercially available cleaning cloth. Wipe
each disc from the center out. Do not use
solvents such as benzine, thinner, commercially
available cleaners, or antistatic spray intended
for analog discs.

Notes on MP3 files

MP3 (MPEG 1 Audio Layer-3) is a standard
technology and format for compressing a sound
sequence. The file is compressed to about 1/10 of
its original size. Sounds outside the range of
human hearing are compressed while the sounds
we can hear are not compressed.
Notes on discs
You can play MP3 files recorded on CD-ROMs,
CD-Rs, and CD-RWs.
The disc must be in the ISO 9660*
level 2 format, or Joliet or Romeo in the
expansion format.
You can use a disc recorded in Multi Session*
* ISO 9660 Format
1
The most common international standard for
the logical format of files and folders on a
CD-ROM.
There are several specification levels. In
Level 1, file names must be in the 8.3 format
(no more than 8 characters in the name, no
more than 3 characters in the extension
".mp3") and in capital letters. Folder names
can be no longer than 8 characters. There can
be no more than 8 nested folder levels. Level
2 specifications allow file names up to 31
characters long.
Each folder can have up to 8 trees.
For Joliet or Romeo in the expansion format,
make sure of the contents of the writing
software, etc.
Multi Session
* 2
This is a recording method that enables
adding of data using the Track-At-Once
method. Conventional CDs begin at a CD
control area called the Lead-in and end at an
area called Lead-out. A Multi Session CD is a
CD having multiple sessions, with each
segment from Lead-in to Lead-out regarded
as a single session.
Notes
• With formats other than ISO 9660 level 1 and level 2,
folder names or file names may not be displayed
correctly.
• When naming, be sure to add the file extension
".mp3" to the file name.
• If you put the extension ".mp3" to a file other than
MP3, the unit cannot recognize the file properly and
will generate random noise that could damage your
speakers.
• The following discs take a longer time to start
playback.
– a disc recorded with a complicated tree structure.
– a disc recorded in Multi Session.
– a disc to which data can be added.
