WHAT ISA MINIDISC? 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 and cuts the frequencies which are inaudible. This compresses the amount of information to be recorded to 1/5 of the normal amount. The ATRAC system is 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 Uuick 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. The limitations of MD Recording on the MD is performed differently from that of a cassette tape or a DAT. Therefore, the MD system is subject to the following restrictions. "DISC FULL is displayed even if the recordeng time does not reach the maximum recordable time of the disc (60-minute or 74-minute). "DISC FULL" is displayed when 254 tracks are already recorded on a disc, without respect to the recording time. "DISC FULL" is displayed even if a disc is not fully recorded on. If there are lots of emphasis data in a particulartrack, the unit handles thedataas index codes, and tracks are counted, in addition, without respect to the time and number of tracks.

WHAT ISA MINIDISC?
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 and cuts the frequencies
which
are inaudible.
This compresses
the amount
of information
to be recorded
to 1/5 of the
normal
amount.
The
ATRAC
system
is
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
Uuick
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.
The limitations
of MD
Recording
on
the
MD
is
performed
differently
from that of a cassette
tape or a
DAT. Therefore,
the MD system
is subject
to the following
restrictions.
“DISC
FULL
is displayed
even
if the
recordeng
time does not reach the
maximum
recordable
time of the disc
(60-minute
or 74-minute).
“DISC FULL” is displayed
when 254 tracks
are
already
recorded
on a disc,
without
respect to the recording
time.
“DISC
FULL”
is displayed
even
if a
disc is not fully recorded
on.
If there
are
lots
of emphasis
data
in a
particulartrack,
the unit handles thedataas
index
codes,
and
tracks
are
counted,
in
addition,
without
respect
to the time
and
number
of tracks.
