Blu-ray Recordable Dvd Technology by Tdk

The new blu-ray Dvd disks introduced by the Tdk Corporation are the Bd-R25, Bd-R50, Bd-Re25 and Bd-Re50. Tdk Bd-R25 and Bd-R50 are "write-once" discs while the other two Bd-Re25 and Bd-Re50 are the "rewritable" blu-ray disks. Tdk (Bd-R25) is single layered and single sided blu-ray disk with capacity of 25Gb. Tdk (Bd-R50) is also single layered and single sided blu-ray disk with more recording capacity of 50Gb. Bd-Re25 is dual layered, single sided blu-ray disk having 25Gb recording capacity. Bd-Re50 is also dual layered, single sided blu-ray disk having twice the recording capacity of 50Gb.

Initially the blu-ray disks used a protected cartridge but now Tdk introduced the technology of Durables-2 (hard coating) in both the Blu-ray Dvd disks of Bd-R & Bd-Re. So, a recording exterior is achieved that is very highly unyielding to dirt, scratches and the fingerprint smudges. Therefore, the users can freely use the blu-ray Dvd disks without any anxiety. Above the recording layer of disk is utilized spin coating of high precision to form the cover layer. So, smoothness is realized at nano level and this ensures stabilized characteristics of playback and recording.

The former types of write once disks used organic dye while the recording layer of new Tdk Bd-R blu-ray Dvd disks use inorganic material. As light does not succeed the recording layer, so the disk realizes mighty achievable. The error rate of Bd-Re is has a very low even after overwrites of 10,000 due to the phase turn material that is highly sensitive. For achieving functioning layer's precision forming of the dual layered 50Gb blu-ray disk, the stacking technology of high precision has been added.

The layer-0 (lower layer) and layer-1 (lower layer) are combined together in terms of recording layer and high sensitivity transparency ratio, ensuring stabilized characteristics of playback and recording. Tdk Corporation's commitment to the advanced technology of optic disk has created the world's first high capacity Blu-ray Dvd disks (25Gb & 50Gb) with capable recording speed of 2X. Bd-R and Bd-Re blu-ray disks from Tdk furnish greater premise along with large data storehouse capacities hence increasing optic recording's potential.

The other name for Blu-ray disks is "Bd disk" which is the optic disk format's next generation. This disk format was joint introduction by the Bda Blu-ray Disk connection (group of clubs that comprise Dell, Hp, Jvc, Hitachi, Apple, Mitsubishi, Pioneer, Lg, Panasonic, Thomson, Sony, Tdk, Philips, Sharp and Samsung). The main purpose for developing this Dvd disk format was to enable the Hd video's rewriting, playback and recording and the capability to hold more volume of data.

The blu-ray Dvd format is more advantageous than the traditional Dvd. The newest technology induced in the blu-ray disk format enables it to hold data more than 5 times as that of which the Dvd can store. The recording capacities of the single layered blu-ray disk are 25Gb and that of the dual layered disk is 50Gb.
The combination of extra data recording capacity and utilization of advanced codec of audio and video furnish the consumers the Hd High definition experience that is unprecedented. The main divergence in the middle of the other disk technologies (Dvd, Dvd-Ram, Dvd±Rw, and Dvd±R) and blu-ray disk format is that the blue-violet laser is used in the blu-ray while red laser is used in the other formats for the function of reading and writing data onto the disk. That is why it has been given the name of blu-ray.

Is Led Tv Technology great For Your High Definition Viewing Pleasure?

Of course these sleek new Led Tvs look outstanding and achieve way great than their predecessors but are we to believe they nothing else but are "better?" We also have to think the marketplace as it is acceptable firm practices nowadays to roll out technology in planned increments to increase sales, you don't want to be stuck with something obsolete do you?

Is Led Tv Technology great For Your High Definition Viewing Pleasure?

Truth is there are plans for even newer and great technological advances for the future. There is already been huge speculation of a 3D Hd Tv to come out when 'Avatar' is released on Blu-ray, now that is the plan so far. If your still gazing into an old tube style Tv and are procrastinating patiently waiting for the most recent high definition Tv to come out that you can keep for years to come than the wait is nothing else but over.

The new Led Tv is what should have been when these slim widescreen Tvs came out in the first place, but that is where that planned roll out came into play. Already there is technology beyond 1080p, however there is nothing that can match it, yet. Cable and satellite feeds only yield 720p and 1080i respectively so the only true Hd comes from Blu-ray. These Led Tvs gives you the deep darkness of a plasma Tv and the glow of the Lcd Tv so it truly is the best out there today. That being said they draw 40% less power and emit no heat, can't say that about a plasma Tv. The older Lcd Tv just couldn't yield those dark colors and looked washed out if you tried to crank up the glow too much.

The Led light has been around for many years, you recently had a string of them in all different colors on your Christmas tree recently, those lights that don't give off heat are used in the same manner. For the Led Tv each pixel has it's own Led light while some fellowships use the out edge to shoot the Led light's glow over the entire screen with those single units being the thinnest out of the bunch.

Let's take a look at what an Led Tv can do and why it is carefully the best.

They are more cost sufficient in terms of power usage and emit less heat thanks to Oled (organic light emitting diode) Led technology. Lighter in weight and thinner in appearance so you will worry less about it falling off the wall if you live in an earthquake zone. A jaw dropping contrast division of 2 million to one (2,000,000 to 1) which lets you see all in high definition which looks great than real life so it will leave you in awe.

The only drawbacks are that you do see everything, and I mean all as to a point of utter distraction. I was watching a recent movie on Blu-ray and could see the actors makeup so vividly it took my focus away from the film. The actors face was caked on with an orange-like makeup while his arms and neck area that did not have stage makeup on were ghostly white. Also it took this dramatic film and made it look like a soap opera, now let me improve on that. A soap opera you see on Tv is shot on tape, not film so that is why it looks like your home movies on a high grade camcorder as the motion appears to be faster and the lighting is more true, film softens and enhances for a more dramatic effect. That is the drawback of such high definition, it loses the soft film potential we have come accustomed to as a society. The 11 o'clock newscasters look frightening as well even in 1080i straight through my cable feed because the makeup department has not caught up yet to the technology yet I suppose, the local nightly news is shot on tape as well.

So if your on the fence about buying one of the most recent Led Tv rest assured you are in fact going to get the top definition in every sense if that is what your after, to each their own. The only technology that can top this is 3D, but now that will take a while to mature as the entertainment manufactures still needs to catch up to it.

New Cd and Dvd Technology -- Blu-Ray and Hd-Dvd

The compact disc has been around since 1978, developed by Phillips and Sony. The fancy it was developed was to take over for the Laserdisc as the commerce approved digital audio disc. Since its invention, we have seen many updates on the compact disc technology. The most up-to-date being the Cd-R and Dvd discs. With the Cd-R, you can now burn your own discs at home, and then modify those discs at a later date. Dvd technology allows us to report video onto a disc, where we used to only be able to report audio and data. As time rolls by, and the disc commerce advances, we are presented with new forms of these technologies. The two new contenders are Blu-Ray discs and Hd-Dvd, here's a minute facts about each of these new disc types.

1. Blu-Ray

Cd and Dvd Blu Ray Technology

This type of disc, also known as Blu-Ray Disc, is the next generation of visual disc. It was developed by the Blu-Ray Disc Association, a group of buyer electronic/Pc/media manufacturers, including: Apple, Hp, Mitsubishi, Phillips, Sony, and others. The Blu-Ray disc type was in general developed for recording, rewriting, and playing back high-definition (Hd) video. It's also perfect for storing large amounts of data, exceeding old Dvd-R disc storehouse capabilities. It can hold more than 5 times the number of facts that a customary Dvd can hold, up to 25Gb single layer, and up to 50Gb dual layer. One of the main differences of the Blu-Ray disc is the type of laser that the disc is read with. Normal Dvds are read with a red laser, the Blu-Ray discs are read with a blue-violet laser. The main benefit of this turn is the wave length of the laser types. The customary red laser has a wider focus, so the blue-violet laser can be focused more de facto allowing more tightly packed data. This equals more data in less space on the disc, this results in the further storehouse space available on the new Blu-Ray discs. These new discs are backwards compatible with quarterly Dvds, which they are expected to replace in the near future.
2. Hd-Dvd
Hd-Dvd discs, High Definition Versatile Discs or High Definition Digital Video Discs, are very similar to the Blu-Ray discs. This disc type is being developed by a group of buyer electronics/Pc companies, headed by Toshiba. They also use a blue-violet laser to read the contents of the disc, which results in an growth in storehouse capacity compared to Normal Dvd discs. The Hd-Dvd can store 15Gb single layer and 30Gb double layer, production their storehouse capacity 10Gb per layer smaller than the Blu-Ray. But Toshiba has announced a triple layer disc that can hold 45Gb of information, and the Hd Dvd discs can hold both Hd Dvd and quarterly Dvd facts on one disc.
Right now these two disc types are battling it out to become the next generation of Dvd disc technology, conjuring up images of the battle in the middle of Betamax and Vhs in the 80's. I guess we're all wondering who's going to come out on top? In my honest opinion, I believe that Blu-Ray will become the new standard. Both disc types offer Hd ability and large data storehouse capacity, so it's kind of hard to say which is better. The Blu-Ray, with its greater maximum storehouse capacity and the fact that it's being backed by more of the large buyer electronic/Pc/media manufacturers, I believe will win the battle. But it's all still up in the air, so only time will tell.
