Sharp MD-SR70H Operation Manual page 9

Notes:
When making important recordings, it is
recommended that you use the AC
adaptor. A fully charged rechargeable
battery or an alkaline battery should be
loaded into the unit. Then, even if a
power failure occurs, the power source
will switch over to the battery automati-
cally.
When recording using the rechargeable
battery or alkaline battery, set the ear-
phone volume level to "0". This will con-
serve battey power. Listening whilst re-
cording will reduce the battery life.
Insert each plug firmly. If the connections
are poor, the recording may not be made
properly. Always keep the plugs clean.
If the plugs are dirty, electrical noise may
be recorded.
Types of discs
There are two types of discs: playback-only
and recordable discs.
Playback-only MiniDisc:
This type of MiniDisc usually contains
commercially available pre-recorded
music. This is the same kind of optical
disc as CDs. Playback is performed us-
ing an optical pickup.
(Recording and editing are not possible.)
There will only
be a shutter on
one side (the back).
Recordable MiniDisc:
This is a "raw disc" on which recording
can be performed.
This is a magneto-optical disc.
Recordings are made using a laser and
a modulated magnetic field. Repeated
recording is possible.
To prevent recorded discs from
being erased accidentally
Slide the accidental erase prevention tab,
located on the side of the disc, in the direc-
tion indicated by the arrow.
The disc will then be protected against
accidental erasure.
Protected against
accidental erasure.
To add a recording to such a disc, slide
the accidental erase prevention tab back
to its original position.

Shutters can be
seen on both
sides of this
type of disc.
