About Atrac, About the recording mode, LP4 | Sharp IM-DR400E

Notes:

"In monaural recording, the sound on the right and left channels is mixed even if the input source is in stereo. Although you can hear the stereo sound from the ear- phones, 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, no sound is heard. (The operation may vary depending on the unit.)

"Tracks recorded in monaural cannot be played on a unit that does not support monaural playback.

!About ATRAC

The ATRAC (Adaptive TRansform Acoustic Coding) sys- tem compresses the sound data into 1/5 by cutting out the inaudible sound. Since the sound is selected based on psychoacoustics masking, the sound quality is not impaired. This unit is equipped with the ATRAC3 com- pressing system that can reduce the sound data to 1/10 or 1/20 of its original size. By employing this system, 2 times and 4 times long recordings are enabled in stereo mode.

!About the recording mode

You can select the recording mode from stereo recording, 2 times long recording, 4 times long recording, and mon- aural recording. Recordable time varies depending on the recording mode. If the tracks are recorded on an 80- minute MiniDisc, its recording time changes as follows:

Indication	Recording mode	Recording
		time

SP	Stereo	MAX. 80 min.
LP2	2 times long (MDLP	MAX. 160 min.
	stereo)
LP4	4 times long (MDLP	MAX. 320 min.
	stereo)
MONO	Monaural	MAX. 160 min.

!Caution for 4 times long recording

(LP4)

Special compression methods are used to achieve 4 times long recording. This may cause some noise to be recorded occasionally. When the highest quality is required, stereo or LP2 recording is recommended.
