Types of discs
There are two types of discs: playback-only and recordable discs.
Playback-only MiniDisc:
This type of MiniDisc usually contains

Recordable MiniDisc:
This is a "raw disc" on which recording

The disc will then be protected against
accidental erasure.
To add a recording to such a disc, slide
the accidental erase prevention tab
back to its original position.
tery consumption will be less than
when listening to the recording whilst it
is being made.
Insert each plug firmly. If the connec-
tions are poor, the recording may not
be made properly. Always keep the
plugs clean. If the plugs are dirty, elec-
trical noise may be recorded.
