Some Words about MDs

There are two types of MDs: premastered (prerecorded) and recordable (blank).

Premastered MDs

Premastered MDs, which have been recorded at music studio, can be played back like regular CDs. On an MD of this type, data is recorded as the presence or absence of tiny pits. A laser beam focuses on the pits on the surface of the MD and reflects the detection back to the lens in the MD Recorder. The MD Recorder then decodes the signals and plays them back as music. This type of MD is called an “optical disc.”

Recordable MDs

Recordable MDs, which use magneto-optical technology, can be recorded and played back repeat- edly. The laser inside the MD Recorder applies heat to the MD, demagnetizing the magnetic layer of the MD for recording and playback. This type of MD is called an “magnetic-optical disc.”

ATRAC (Adaptive TRansform Acoustic Coding)

The MD provides 74 minutes recording and playback time, the same as an audio CD, but in a diameter of only 64 mm. This ability to store such a large amount of data is the result of ATRAC, an audio compression technique developed for MD. This technology, cuts out faint sounds that would not be heard by the human beings. This technology, based on human sensitivity to sounds, enabled the recorded data to be about one-fifth of the original data.

UTOC (User Table Of Contents)

Found only on recordable MDs, this area contains sub-data (track number, recording data etc.) which can be rewritten by the user.

UTOC enables us to search tracks quickly and edit tracks on the MD.
