Getting to know the MD

Structure

The 2.5-inch MiniDisc (MD) is compact and
easy to handle requiring less care as it is
encased in a plastic cartridge that looks like
a 3.5-inch diskette (see illustrations below).

Disc variation

MDs come in two types: pre-mastered (pre-
recorded) and recordable (blank). Pre-
mastered MDs cannot be recorded on or over
like cassette tapes. To record, you must use
a “recordable MD”.

Pre-mastered MDs

Pre-mastered MDs are recorded and played
like regular CDs. A laser beam focusses on
the pits on 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.

You can make only a first-
generation copy* through a
digital-to-digital connection.

That is:

1

You can make a copy of a digital sound
programme on the market such as CDs,
MDs, etc., but you cannot make a second
copy from the first-generation copy.

2

You can make a copy of a digital signal
from a digitally-recorded analog sound
programme on the market such as an
analog record, music cassette tape, etc., or
from digital satellite broadcasts, but you
cannot make a second copy.

Note

No restrictions apply when a digital signal is
recorded as an analog signal (that is, when a
digital signal is recorded through analog-to-analog
connection).

* A first-generation copy is a digital recording of a

digital signal made on digital audio equipment
through a digital-to-digital connection.
