What is an MD
The small, compact cartridge containing a 64mm diameter disc is very easy to handle. The signals on the disc are digital and are read without touching the disc, so the quality of the sound remains unchanged upon playback (unlike cassette).
It uses a recording method called ATRAC (Adaptive TRansform Acoustic Coding). This is a compression technique used to reduce the music data to 1/5 of its original size. This compression is such that the quality of the sound approaches that of a Compact Disc.
Handling
The MD is enclosed in a plastic cartridge. If can be handled without worrying about dust or fingerprints. However, dust can still enter from the small gaps in the case or mishandling the MD could damage the unit.
Please follow the instructions below when using the MD.
•Do not open the shutter.
•Do not touch the disc inside cartridge.
•Wipe off any dust or debris on the cartridge. Pay special attention to the spindle side of the MD.
•Do not expose to direct sun light.
•Do not expose to a location where sand or dust could enter.
•Make sure labels are properly positioned.
•Use only 1 label per MD.
•Do not use an MD with its label peeling off.
•Store in its case when not in use.
