CD TEXT

CD TEXT is a system that is standardized to allow the display of text
data (disc name or song title, artist name etc.) that is recorded on CDs
in addition to music.
By digitally connecting this unit with a CD player (CD TEXT compatible),
the text data of a CD can be copied to an MD.
Presently (1997), however, some CDs are equipped with a copy
prevention code that prohibits the copying of this data. In the case of
such CDs, copying of text data is not possible.
On CDs that do not include the text data copy prevention code, the
operation of “CD text editing” is possible.

i

MD system

The Mini Disc system has the features as summarized in the following.

1 Like CD (Compact Disc), playback can be started from any position. (Random access)
2 It uses a disc with a diameter of 64 mm that is accommodated in a cartridge.
3 Two types of discs can be used. (playback only discs, recordable / playable discs).
4 Up to 74 minutes of recording or playback is possible using high-efficiency coding technology.
5 Countermeasure against vibration is taken using semiconductor memory chip.

DM-9090 (En)

Playback-only Mini Disc

This type of MD can be used only for playback,
and is used by the commercially-available mu­sic MD software packages. The playback-only
MD is an optical disc like the Compact Disc
(CD). The signals are recorded as the presence
or absence of small pits and read out by an
optical, non-contact pickup.

Recordable Mini Disc

This MD is a magneto-optical disc which can
be recorded by magnetic field modulation. To
record signals, laser light is irradiated from the
bottom side of the magneto-optical disc and
magnetic field is applied from the upper side
of it.

Sound-skip prevention memory

During playback, this unit always stores signals in memory temporarily to prevent sound from being skipped in case of vibration. As a result, even
when the data from the optical pickup is interrupted due to vibration, etc., the music will not be interrupted because the memory holds the data for
several seconds.

Reproduced sound

High-efficiency coding technology “ATRAC” (Adaptive TRansform Acoustic Coding)

The Mini Disc has only a half the size of the Compact Disc but provides the same recording time. This is made possible by ATRAC*, a newly developed
high-efficiency coding technology.
The ATRAC compresses the music data to about 1/5 the amount of data which would be obtained with conventional technology, by cutting off the
sound components which do not pose problem in audition even when they are not present. This has made it possible to record or play up to 74 minutes.

Lowest and highest
frequencies are not audible
unless the sound has a
certain level of volume.

Monaural recording

This unit can record a longer period of sound in monaural (monaural long-play mode). In this mode, the recording time of the disc is about double that
in the stereo mode.
The Mini Disc recorded in the monaural mode cannot be played with equipment which is not compatible with monaural playback.

Disc recorded in monaural mode

This unit is capable of playing a Mini Disc recorded in the
“monaural long-play mode.” As the “monaural long-play
mode” requires half the amount of data required for
stereo mode recording, the playing time (recording time)
of the disc is doubled (to max. 148 minutes) from that in
the stereo mode.

÷ A Mini Disc recorded in the “monaural long-play mode” cannot be

played normally with equipment which is not compatible with
monaural playback.
