MD system

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.

During normal playback In case of vibration

Reproduced

sound

When the readout from disc

is interrupted momentarily

due to vibration or shock, the

reproduced sound from the

memory will not be inter-

rupted.

The sound data for several

seconds is always stored

during playback.

Mini Disc

Small sound near large sound

A small sound is not audible to human ears if it is

produced at the same time as a large sound. (Mask-

ing effect)

Sound does not affect the sensitivity of ears

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 80 minutes.

Lowest and highest

frequencies are not

audible unless the

sound has a certain

level of volume.
