Sharp MD-MT877H Mode D'emploi page 135

Notes:
Tracks can be recorded in stereo recording mode, 2 times
long recording mode, and 4 times long recording mode on
one MiniDisc.
In monaural recording, the sound on the right and left chan-
nels is mixed even if the input source is in stereo. Although
you can hear the stereo sound from the earphones, the
recorded sound is monaural.
Tracks recorded in 2 times long recording and 4 times long
recording modes cannot be played with the unit that does
not support these modes. On such a unit, "LP" is displayed
at the beginning of the track and no sound is heard. (The
operation and the display may vary depending on the unit.)
Tracks recorded in monaural cannot be played if equip-
ment does not support the monaural playback.
About the recording mode
You can select the recording mode from stereo recording, 2
times long recording, 4 times long recording, and monaural
recording. Recordable time varies depending on the record-
ing mode.
If the tracks are recorded on 80-minute MiniDisc, you can
record them in the following 4 modes:
Indication Recording mode Recording time
SP/STEREO Stereo Max. 80 min.
LP2 REC 2 times long (stereo) Max. 160 min.
LP4 REC 4 times long (stereo) Max. 320 min.
SP/MONO Monaural Max. 160 min.
Caution for 4 times long recording (LP4)
Special compressing method allows the 4 times long record-
ing to realize long-time stereo recording. Therefore, some
noise is recorded occasionally.
If sound quality is the main requirement, stereo recording or
2 times long recording is recommended.
About ATRAC
The ATRAC (Adaptive TRansform Acoustic Coding) system
compresses the sound data into 1/5 by cutting out the inau-
dible sound. Since the sound is selected based on psychoa-
coustics masking, the sound quality is not impaired.
This unit is equipped with the ATRAC3 compressing system
that can reduce the sound data to 1/10 or 1/20 of it's original
size.
By employing this system, 2 times and 4 times long record-
ing is enabled in stereo mode.
