WHAT IS A MINIDISC? GEES
A Mini Disc is only 64 mm (2 §/s inches) in diameter,
about half the size of a conventional CD. But Mini
Disc can be used to store and play back a full 74
minutes of information, as much as a CD. Unlike a
CD, a Mini Disc comes in a plastic cartridge, so that
it can be handled with ease.
The cartridge also
protects the disc inside from shocks, dust and
scratches. Unlike cassette tapes, which canbecome
stretched or tangled, a MiniDisc is an excellent
durable media.

Two types of discs
There are two types of MiniDiscs: "Optical discs"
and "Magneto-optical discs". Both types use laser
beams and optical pick-up technology to read
recorded information during playback.
Optical discs -©
These are playback only discs. Like CDs, they are
used as prerecorded music discs.
You cannot
record or edit them.
Recordable MO* discs —-@
These are recordable discs which can be recorded
on again and again, like cassette tapes.
The
recording
method
called
magneto-optical
technology employs a laser and magnetism to
record signals. Therefore, the quality of recorded
sound
does not deteriorate even
after many
playbacks and recordings.
* Magneto-optical
Ultra compact size made possible by ATRAC*
technology
A newly developed digital audio compression
technology
called
the
ATRAC
system
automatically extracts only the frequencies that
are actually audible to the human ear andcuts the
frequencies which are inaudible. This compresses
the amount of information to be recorded to 1/5 of
the normal amount. The ATRAC systemis based
upon studies carried out in the field of auditory
psychology and does not impair the quality of the
audible sound.
* Adaptive Transform Acoustic Coding
Quick random access
One of the great features of the MiniDisc is that
you can search for desired tracks quickly, There
are also quick and easy functions for random
playback, in which the order of the tracks can be
rearranged randomly, and for renumbering tracks
to play them in any order.
