What is a MiniDisc?
A MiniDisc is a 2-1/2" (64 mm) diameter disc which is
stored in a cartridge. MiniDiscs are easy to handle, com-
pared to compact discs, because they are protected
against dust and scratches.
Recording and playback use a digital system with a
sound quality that is similar to that found on compact
discs.
MiniDiscs cannot twist or stretch like tapes. The quality
of sound will not deteriorate. MiniDiscs are extremely
durable.
Never disassemble MiniDiscs.
Adaptive TRansformed Acoustic Coding
[ATRAC]
The ATRAC (Adaptive TRansformed Acoustic Coding) is a
new technology that is designed to eliminate the information
in sounds which you can not hear and to compress the
remaining sound data so that the recording uses about 1/5
of the original sound information.
Sound data is analyzed and filtered to take advantage of
psycho acoustic masking. The acoustic quality of the sound
is not impaired.
