	Premastered MDs are recorded and played

	recorder. The recorder then decodes the
	signals and plays 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 field 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.
