What is MO?
How MiniDisc works
MiniDisc (MD) comes in two types:
prenustered (prerecorded) and
rtvordable (blank). Premastered MDs,
recorded at music studios, can be playcM
back almost endlessly. Howewr, they
can't be rcvi>rded on or m er like cassette
tapes. To record, you must use a
"recordable MD".
Premastered MDs
Premastered MDs are recorded and
played like regular CDs. A laser beam
focuses on the pits in the surface of the
MD and reflects the information back to
the lens in the recorder. The recorder then
decodes the signals and plavs them back
as music.
Recordable MDs
Recordable MDs, which use magneto­
optical (MO) technology, can be recorded
again and again. The laser inside the
recorder applies heat to the MD,
demagnetizing the magnetic layer of the
MD. The recorder then applies a magnetic
field to the layer. This magnetic held
corresponds exactly to the audio signals
generated by the connected source. (The
north and south polarities equate to
digital "1" and "0".) The demagnetized
MD adopts the polarity of the magnetic
field, resulting in a recorded MD.
