Playback-only Mini Disc
This type of MD can be used only for playback, and is used by the commercially-available music MD software packages.
The playback-only MD is an optical disc like the Compact Disc (CD). The signals are recorded as the presence or absence
of small pits and read out by an optical, non-contact pickup.

Recordable Mini Disc
This MD is a magneto-optical disc which can be recorded by magnetic field modulation. To record signals, laser light is
irradiated from the bottom side of the magneto-optical disc and magnetic field is applied from the upper side of it.
