ATRAC (Adaptive TRansform Acoustic
Coding)/ ATRAC3
The MD provides 80 minute recording and playback time,
much more than an audio CD, but in a diameter of only
64mm. This ability to store such a large amount of data is
the result of ATRAC, an audio compression technique de-
veloped for MD. This technology cuts out faint sounds that
would not be heard by the human beings. This technology,
based on human sensitivity to sounds, reduces recorded
data volume up to about one-fifth of the original data vol-
ume.
Furthermore, this unit takes advantage of the latest ATRAC 3
techniques, which can reduce the amount of data to record
to one-10th or one-20th of the original data volume. This
allows for 2 times or 4 times long-hour stereo recording on
this unit.

Sound skip guard memory
With the minidisc, the data of the track being played can be
temporarily stored up using a function called "sound skip
guard memory". Even when data cannot be collected prop-
erly from the disc due to shaking or vibrations, information
is stored in the "sound skip guard memory", so that there is
no break in the sound which is actually delivered.
UTOC (User Table Of Contents)
In a minidisc, apart from the recorded tracks, there is the
"UTOC". In this area, information such as the position
where each track is recorded, the track divisions, and track
order are listed. When music search is done, the UTOC is
consulted, and the tracks are quickly found and played
back. When editing is done, only the UTOC is changed, so
there is no need to re-record the tracks.
