Development of optical drive for a while has not stopped. The need for capacity that is much more to realize the birth of Blu-ray and HD DVD. But not only that, the chip will come with a larger capacity.
Discussion of the previous reviews have been mostly about the next generation optical drives that are now popular. Namely, in the second generation of optical drives (second-generation optical disc), and is usually found on almost every PC.
In the discussion this time, will cover more about the upcoming generation (third-generation) that will in the near future is believed to be new trends in the optical drive. For while still referred to as the generations to come, although in fact some producers have already issued a product that supports their use. But not be merged with either by the users, particularly in Indonesia. Development of this next generation will presumably dominated by two candidates who supported the industry of the world.
Basically, this fragment capacity development is driven more from the need for HDTV (High-Definition television). Increase in the number of pixels in each frame rate, the consequences need to provide a greater capacity from time to time. So, if not bizarre development is also supported by the film industry.
Details images better and more realistic also want the gamer, including the game console. Consequently needed a storage-media trends in the gaming console later also use optical-storage with a capacity sufficient to store data. That's why the development of this generation is also supported by the manufacturer of large, giant game console.
Increase capacity, of course, be a useful alternative in the use of computers in the world. So, no wonder if the industry in the fields of computer, whether it is also the system integrator component manufacturers, especially those who produce ODD (optical disc drive) also support the development.
The most significant will be coming soon is Blu-ray. The realization of its use will most likely be applied to the PlayStation 3. Terdekatnya is a rival HD-DVD. What and how the basic principles of the Blu-ray and HD DVD? Is there a technology other than both of them, in the third generation optical disk is?
Blu-ray Disc
Blu-ray Disc (BD) is the result of the development by Blu-ray Disc Association (BDA), which consists of producers in the field of consumer electronic, computer components, up to the Hollywood film industry, including Twentieth Century Fox, Walt Disney Pictures and Television, and Warner Bros.Entertainment.
The name Blu-ray is taken from their own species / color laser is used, the more precise blue-violet. Writing without the letter 'e' in the word blue is a deliberate, following the naming rules issued from the BDA.
As a development from the previous generation, of course, has a capacity far greater than if the next generation of optical disc. Many advances in technology that is used on a standard optical disc of this one.
With the red laser DVD using the ray with the wavelength 650 nm. Meanwhile, the BD-ray with the wavelength 405 nm. So that is able to have the capacity to 25 GB single layer and 50 GB for dual layer.
Use is predicted to be more popular again with the same use of Blu-ray disc on the PlayStation 3 officially akan coast in November 2006.
Technology Used
Technological, BD is a major progress in technology for optical-disc. With the amount of data capacity per layer is also the largest compared with generasinya.
This is possible because BD actually can be said to replace all the technology of optical drives, in order to eliminate some of the technical limitations of the technology tools.
The main difference in the BD is also visible in the distance between the eyes with the laser data layer that is closer than the other optical-disc. This is intended to prevent the occurrence of birefringence or double refraction. This is a situation in which the rays will be to separate two-way (or more) after passing through other materials. Bring together the distance between the data layer to the laser, Blu-ray try to improve the accuracy to be better than the first optical disc.
