Ultra compact size made possible by ATRAC*2 technology

A newly developed digital audio compression technology called the ATRAC system automatically extracts only the frequencies that are actually audible to the human ear and cuts the frequencies which are inaudible. This compresses the amount of data to be recorded to 1/5 of the normal amount. The ATRAC system is based upon studies carried out in the field of auditory psychology and does not impair the quality of the audible sound.

*2ATRAC: An abbreviation of Adaptive Transform Acoustic Coding

Quick random access

One of the great features fo the MD is that you can search for desired tracks quickly. There are also quick and easy functions for random playback, in which the order of the tracks can be rearranged at random, and fro renumbering tracks enabling them to be played in any order.

THE LIMITATIONS OF MD

Recording on the MD is performed differently from that of a cassette tape or a DAT. Therefore, the MD system is subject to the following restrictions.

"TOC*FULL" is displayed even if the recording time does not reach the maximum recordable time of the disc (60-minute or 74-minute)

"TOC FULL" is displayed when 254 tracks are already recorded on a disc, without respect to the recording time. *TOC: An abbreviation of Table Of Contents.

"TOC FULL"is displayed even if a disc is not fully recorded on

If there are lots of emphasis data in a particular track, the unit handles the data as index codes, and tracks are counted, in addition, without respect to the time and number of tracks.

The remaining time on a disc is not increased even after some short tracks have been erased

When the remaining time on a disc is displayed, it may not be increased even after erasing short tracks because the sections less than eight seconds are not counted.

Tracks cannot be joined (the COMBINE function does not function).

Tracks created by editing may not be joined.

The total of the recorded time and the remaining time on a disc does not match the maximum recordable time of the disc (60-minute or 74-minute)

Recording is performed in a minimum unit of one cluster (two seconds). Even if the recorded section is shorter than two seconds, a two-second space is needed in recording. Therefore, the available time becomes shorter. If there are scratches on a disc, the available time becomes even shorter, because the sections which are scratched are automatically erased.

Track numbers may not be registered properly

When recording from a CD with the CDMD button, small tracks may be created depending on the contents of a CD. When using the AUTO MARK function, track numbers may not be registered properly depending on the contents of the CD.

Digital inputs may be acceptable

When digital recording is attempted form recorded material with copyrights, digital dubbing cannot be performed to a recordable MD from another MD recorded in digital because of the built-in record restriction function which complies with the SCMS* standard.

*SCMS (Serial Copy Management System) is the standard to restrict single digital dubbing between digital audio systems thus protecting copyrights.
