2. INTRODUCTION
Today discs durability has always been in
question, regardless of format. A mark or fall can
ruin whole gigabytes of data, and in many
cases are not recoverable. In an attempt
todramatically increase the strength of optical
discs, we have designed an album that, in
addition to maintaining backward
compatibility with current DVD drives and Blu-
ray, is created from a material "similar to
the rock."

3. OBJECTIVES
Knowing the benefits of the new M-Disc CD.
Investigate the physical properties of M-Disc.

5. An M-Disc is similar to a DVD or a Blu-ray, but the secret
is in their material, and we literallysecret, because its
developers have not revealed anything beyond the fact
that it issomething with properties "similar to the of the
rock. "Another important detail is that an M-Disc drive does
not have a reflection layer as conventional optical discs,
another knownpoint of vulnerability. A further strength of
the material, the M-Disc requires the recording
laser is more
powerful. Therefore, a conventional burner can not write
to a disk M-Disc (ifyou're talking about firmware updates),
but you can read it.

7. In the diagram above we can tell the
difference between a DVD (traditional optical disk)
and a M-
DISC. All optical drives are designed as sandwich,
where the "bread tapas" arepolycarbonate
discs and "stuff" we have a dye that is burned,
literally, to store information.The M-DISC come
to change this paradigm, because this layer is
solid and it createsgrooves that make it
completely impossible to erase the information.

8. Millenniata is so sure that they have created
a diskA indestructible so much that they dare to say
that you can have a useful life of 1000 year ± os and
without accepting blame, asSega º n them the layers
of polycarbonate that wear are the limiting the
durability of theirtechnology. A strength of this format
is that nuevoÂ, because the secret is in how you
record, no need to switch devices to enjoy it, because
it is compatible with current playersARVD idea.

9. el M-Disc o “disco de piedra” puede soportar una
temperatura de entre 180 grados Celsius bajo cero y
los 80 grados Celsius sobre cero.
El costo de cada uno de estos “discos de piedra”
rondarán los us$ 3.00 lo que no los hace en absoluto
costosos, teniendo en cuenta que según LG y
Millenniata estos M-Disc pueden durar más de 1000
años. En el prototipo del “disco de piedra” M-Disc, la
capacidad actual es de 4.7 GB, similar a la de un
DVD, pero ya se está trabajando para aumentarla para
que alcance la capacidad de un Blu-ray.

10. CONCLUSIONS
It is an innovative product that has some nice
features available to consumers, durability of their
albums, better protection of information.
