Your dealer may not handle some of the above listed accessories. Please ask the dealer for detailed information about the accessories in your country. ∗ When using optional headphones, use only headphones/earphones with stereo mini plugs. You cannot use headphones/ earphones with micro plugs. Explanations What is "Net MD"? Net MD is a format of that allows the highspeed transfer of audio data from a computer to a MiniDisc device over a USB (Universal Serial Bus) cable using the highly sophisticated OpenMG and MagicGate copyright protection technology. Since this format entails no change in the MiniDisc recording system, it supports the use of existing MiniDiscs and the playback of transferred (checked-out) audio data on existing MiniDisc devices.* This format also allows the use of the OpenMG Jukebox software for easy editing or input of characters on your personal computer. ∗ Audio data transferred in LP mode must be played on MiniDisc devices that support MDLP mode. How the MiniDisc got so small The 2.5-inch MiniDisc, encased in a plastic cartridge that looks like a 3.5-inch diskette, uses a new digital audio compression technology called ATRAC (Adaptive TRansform Acoustic Coding). To store more sound in less space, ATRAC extracts and encodes only those frequency components actually audible to the human ear. The meaning of "no sound" "No sound" describes a recorder condition in which the input level is about 4.8 mV during analog input or less than -89 dB during optical (digital) input (with 0 dB as full bit (the maximum recordable level for a MiniDisc)). Quick Random Access Like CDs, MDs offer instantaneous random access to the beginning of any music track. Premastered MDs are recorded with location addresses corresponding to each music selection. Recordable MDs are manufactured with a "User TOC Area" to contain the order of the music. The TOC (Table of Contents) system is similar to the "directory management system" of floppy disks. In other words, starting and ending addresses for all music tracks recorded on the disc are stored in this area. This lets you randomly access the beginning of any track as soon as you enter the track number (AMS), as well as label the location with a track name as you would a file on a diskette.

Explanations
What is
“
Net MD
”
?
Net MD is a format of that allows the high-
speed transfer of audio data from a computer
to a MiniDisc device over a USB (Universal
Serial Bus) cable using the highly
sophisticated OpenMG and MagicGate
copyright protection technology.
Since this format entails no change in the
MiniDisc recording system, it supports the
use of existing MiniDiscs and the playback
of transferred (checked-out) audio data on
existing MiniDisc devices.*
This format also allows the use of the
OpenMG Jukebox software for easy
editing or input of characters on your
personal computer.
∗
Audio data transferred in LP mode must be
played on MiniDisc devices that support
MDLP mode.
How the MiniDisc got so small
The 2.5-inch MiniDisc, encased in a plastic
cartridge that looks like a 3.5-inch diskette,
uses a new digital audio compression
technology called ATRAC (Adaptive
TRansform Acoustic Coding). To store more
sound in less space, ATRAC extracts and
encodes only those frequency components
actually audible to the human ear.

Quick Random Access
Like CDs, MDs offer instantaneous random
access to the beginning of any music track.
Premastered MDs are recorded with location
addresses corresponding to each music
