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
(see illustration above), 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)).
