Mitubishi EC has announced it has developed a semiconductor laser that goes by the name ML1XX20. This new laser will be able to write both DVD minus and DVD plus DVD recordables at 8 speed. The part that will likely be used in future DVD recorders will be available from about June 2003.

The DVD±R/RW of large capacity has spread suddenly attendant upon the improvement of the personal computer and the acceleration of Internet, as a external memory unit. Entry speed of the DVD±R/RW which presently is marketed with 2 time fast - 2.4 time speed, is seen as the thing where the product of 4 time speed of the 2nd generation is thrown to the market from around end of 2002, but furthermore acceleration of 8 time speeds or more is required. The DVD disk equivalent of 1 (the 4.7GB) as for the data quantity, with 4 time speed approximately 14 minutes, with 8 time speed it can write in approximately 7 minutes.
The DVD±R destroys the pigment layer of the optical disk with red LD optical lighting, forms the pit and remembers. In order to increase the entry speed of the data, it irradiates the red LD light of higher output, it is necessary to do pit formation at brief. This corporation the 100mW which from March of 2002 corresponds to the entry speed 4 time speed (pulse) has sold the high output red LD of optical output, but this time, the 140mW of the worldwide highest output which corresponds to 8 time speed (pulse) it succeeded in the development of the red LD which actualizes optical output.
So in June 2003 this company will be able to deliver drive manufacturers with 8x DVD writing speeds, the companies will probably need some time to implent it, but it's likely that before 2004 we are at 8 times DVD writing speed which should mean you would be able to write a DVD recordable in about 7 minutes!
