What is an MD?

How MiniDisc works

MiniDisc (MD) comes in two types:

premastered (prerecorded) and recordable

(blank). Premastered MDs, recorded at

music studios, can be played back almost

endlessly. However, they can’t be recorded

on or over 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 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.
