What is Blu-Ray disc technology and why it is getting popular?
If you need to record high-definition programs such as movies and Television videos, or backup your data from computer that could include your important photos, music library as well as data from your office or scholl work, then you need a reliable storage medium to backup your data. Blu-ray is arevolutionary new disc technology which utlizes state of the art technology to enable high speed, precision to achive larger capacity storage on a single disc surface. A blu-ray disc will allow 25GB of digital data recording on a single side disk surface.
The Blu-ray Disc Technology.
New age of High Definition Require High Capacity Storage Medium.
From cd to dvd and now optical discs that meets the needs of even greater capacity. With the advent of high definition video, it is evident that larger capacity discs are needed. Data archiving requirements are also driving demands for increased capacity. In conjunction with the development of short wavelength blue-violet laser, the age of higher capacity discs has arrived. Against this backdrop the bluray disc is emerging as the optical disc of the future.The Blu-ray Disc: The Ultimate Optical Disc.
A single sided 25 gigabyte blu-ray disc hosts the capacity of approximately 36 cds.
To enable this huge capacity, the bluray disc incorporates a track pitch of 0.32 microns, compared to the 0.74 microns track pitch of DVD disc. The diameter of the laser spot is about one fifth as that of DVD. Because of the blue violet laser short 405 nano meter recording wavelength and the object lenses large 0.85 numerical apperture, the recording layer must be situated extremely close to the disc surface.Innovative TDK Technology Incorporated into the Blu-ray Disc.
Cover Layer of Blu-ray Disk Surface.
The blu ray recording material is protected only by 0.1milimeter thick cover layer, that comprises the disc’s top surface. Due to the extremely short laser beam of only 405 nano meter wavelength that utilized for recording and playback, absolute uniformity in the thickness and smoothness of this cover layer is critical for the disc performance.What are the benefits of spin coating method?
creates a cover layer supremely flat and uniform.
Techniques used to form 0.1mm thick cover layer include the bonding sheet method and the spin coating method. TDK exclusive spin coating technology creats a supremely flat and uniform cover layer enables precise control of the cover layer thickness. This precision makes it possible to obtain a stable servo signal and reducing the servo circuitary load and insuring absolute stability in the recording and playback signals. The result is unrival disc performance in terms of reliability and compatibility. TDK’s unique high precision spin coating method is also enabling the companies to advance capacity and speed abilities for the future of the blu-ray format.DURABIS, a revolutionary hard coating technology, safeguards the disc.
For better scratch resistance, super dirt resistance.
The diameter of the blue laser spot on the disc surface is extremely small at approximately 130 micons, which is only around one fifth the size utilized by the DVD. For this reason, in comparison to DVD, the bluray disc is more resistable to scratches or fingerprints on it’s disc surface, which can prevent accurate laser beam tracking. thus risking the loss of important data or content. For a bare bluray disc, a hard coating that protects the disk surface is absolutely essential. DURABIS, a TDK’s exclusive hard coating formulation utilized on the bluray disk is a revolutionary technology with several major advantages. Here is a comparison of two disc surfaces after of these rubbed with a steel wool scouring pad. As you can see the TDK bluray disc with it’s DURABIS coating displays overwelmingly superior scratch resistance. Also the disc resists finger-prints, drastically reducing laser beam interference. The TDK DURABIS coating made it possible for the blu-ray format to realize bare discs hosting high durability and reliability with no need to encase the discs in an expensive and bulky cartridge.Write-once type utilizing inorganic material.
Players With Technology to read and write data on Blu-ray Disks.
For the wite-once type utilizing the inorganic material, which consists of a silicon layer and a copper alloy layer. This recording layer not only enables fast and stable 72Mbps recording speeds but also makes it possible to realize larger capacities through multi-layering and out-standing archive-ability.Potential for even greater capacity.
Ultimate disc with High quality, High speed, High capacity.
TDK has already announced the development of world’s first write-once type disc to realize a huge 100GB capacity. This is accomplished by using a four layer inorganic recording material structure. The 100 Gigabyte disk provide s the capacity required to store more than 10 hours of full high-definition video on a single disc. TDK has also achieved a transfer rate of 216Mbps. This is the world’s fastest speed, six times that of the current blu-ray disc. What’s more TDK is currently roadmapping the future of the bluray and is on the verge of creating a 200GB high speed optical disc.Verbatim 97457 25 GB 6x Blu-ray Single Layer Recordable Disc BD-R, 25-Disc Spindle
