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."
OBJECTIVES Knowing the benefits of the new M-Disc CD. Investigate the physical properties of M-Disc.
CARACTERISTICS
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.
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.
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 nuevo , because the secret is in how you record, no need to switch devices to enjoy it, because it is compatible with current playersARVD idea.
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.
CONCLUSIONS It is an innovative product that has some nice features available to consumers, durability of their albums, better protection of information.
