what do u guys say about this???

[doc_sameer]

Very old "news" tutu...

In fact, Sony (blu ray) & Toshiba (DVD-HD) are having a big battle about whose format should be adopted..

Blu Ray has theoretically more capacity than Toshiba's DVD-HD... but blu ray has copy protect features which makes it popular with the Movie studios like Universal while Tohishiba's disc is popular with Microsoft & Other Tech powers...

The battle is reminiscent of the earlier battle between Sonys betamax & JVC's VHS for video casettes... ultimately VHS was adopted as the standard but not before several customers bought SOny's format players...

Hope everything settles down b4 the release.... no progress yet though...

[VLADIFTODI]

yes, doc is right, dell hp sony and others support blu ray, while intel, microsoft toshiba support hd-dvd

[amjad_z4]

how much does a 100 GB RW cost????

[ibsays]

tutu... really old news...

but atlast DVD is passe :lol:

[VLADIFTODI]

still most people still use cd's, and it's aconsidered that they (will survive at least another 15 yerars)
why?
high write\read speed max 32 write at rw and 52 write on r, and read is 52x
and considering that hd burn technology alows burning of 1gb in a 700 mb disc , the popularity has grown

[Pasha LP]

Hey Vladi What about floopy????????????:banana: :banana:

????????????
what allows 1gb on 700mb disk????
please tell me how!!!!!

The present burners & CD Recognition systems employ "red Laser"

The lesser the wavelength of the Laser, the more data it can store on the surface of a CD

Blue laser has the least wavelength & it scatters less... hence it can burn a very large amount of data on a small surface...

A laser (an acronym for "light amplification by stimulated emission of radiation") is a coherent (meaning all one wavelength, unlike ordinary light which showers on us in many wavelengths) and focused beam of photons or particles of light. The photons are produced as the result of a chemical reaction between special materials and then focused into a concentrated beam in a tube containing reflective mirrors. In the blue laser technology, the special material is gallium nitride. Even a small shortening of wavelength of light can have a dramatic effect in the ability to store and access data. A shorter wavelength allows a single item of data (0 or 1) to be stored in a smaller space.

Red lasers used in today's technologies have wavelengths of over 630 nanometers (or 630 billionths of a meter). The blue laser has a wavelength of 505 nanometers.

Now, if u make the CD a double layer... then multiple it by 2... i.e. twice the surface than one layer... so original data x 2 times...

Now if u keep on adding layers, u can increase the surface that many times... hence 4 layered cd can have 4 times the data as of single layered...

from Wikipedia: http://en.wikipedia.org/wiki/Blu-ray_Disc

Variations and sizes

A single-layer Blu-ray disc (BD) can store enough for approximately two hours of high-definition video with audio on a single layer 25 GB disc. A dual-layer BD 50 GB disc can hold enough for approximately four hours of HD video. TDK recently announced that they have created a working Blu-ray disk capable of holding 200GB of data (6-33GB data layers).


Laser and optics

Blu-ray systems use a blue-violet laser operating at a wavelength of 405 nm, similar to the one used for HD DVD, to read and write data. Conventional DVDs and CDs use red and infrared lasers at 650 nm and 780 nm respectively.

The blue-violet laser's shorter wavelength makes it possible to store more information on a 12 cm CD/DVD sized disc. The minimum "spot size" on which a laser can be focused is limited by diffraction, and depends on the wavelength of the light and the numerical aperture of the lens used to focus it. By decreasing the wavelength, using a higher numerical aperture (0.85, compared with 0.6 for DVD, and 0.65 for HD DVD), higher quality, dual-lens system, and making the cover layer over the data level thinner (0.1mm (Blu-ray) vs 0.6mm (HD-DVD)) to avoid undesirable optical effects, the laser beam can be focused much more tightly. This produces a smaller spot on the disc than in existing CDs or DVDs, and allows more information to be physically stored in the same area.

HD-BURN Features

SANYO Electric Co., Ltd. has developed a high-density writing technology, "HD-BURN", which has allowed conventional CD-R media (700MB) to doubles the writing capacity (1.4GB). "HD-BURN" will be subsequently adopted into our Super Combination Drives. In addition, SANYO has formulated the standard of the writing format and started the product licensing

CD-R media remarkably became widespread because of its reasonable price and the superior compatibility. On the other hand, the needs for large volume of data writing, such as video writing have grown. For large volume of data writing, DVD media (4.7GB) will become widespread as well. In addition, users demand the media, which have intermediate range of the capacity between CD-R and DVD since there is a large capacity difference between these 2 media. Besides these capacity variation demands, users also demand usability and affordability. "HD-BURN" technology meets these needs and realizes large volume data writing at a moderate price.

A written disc by "HD-BURN" technology is compatible with a DVD player, and allows the player to read the disc with some modification of firmware. SANYO Electric Co., Ltd. will disclose the technology used to read the media written with "HD-BURN" technology by a DVD player, and will propose to other DVD drive manufacturers that they adopt this technology as an industry standard.

Benefits of the HD-BURN technology to users

1. Double capacity
The high-density writing technology, "HD-BURN" allows a conventional CD-R media to write twice as much as its own capacity. This drive is ideal for large volume data storage such as video data.
2. High speed writing and reading
"HD-BURN" mode allows 36X (CD-ROM) writing speed and 80X (CD-ROM) reading speed at the maximum by using CLV (Constant Linear Velocity) format.
3. BURN-Proof prevents writing errors caused by Buffer Under Run errors
4. Support for CD-RW media
CD-RW media support by HD-BURN will be realized by modified firmware in the future. CD-RW media support by HD-BURN enables 24X data writing speed at the maximum for commercial CD-RW media.
5. Applications software
Available applications software for writing are B's GOLD by B.H.A and Nero by AHEAD. Users can easily use HD-BURN writing technology since these applications have DVD video writing feature and Video authoring feature.

LIGHTSCRIBE - BURNING A LABEL

GET READY TO BURN, FLIP, BURN.

Just follow these steps to begin creating personalized labels that are 100% you.

Remember, making labels and burning your data are two separate steps. You may burn your data either before or after you burn your label.

1.
Check to make sure you have a LightScribe-enabled product. To do this, look for a LightScribe logo on the outside of your drive or your computer.

Learn more about LightScribe-enabled hardware. (http://www.lightscribe.com/products/index.aspx?id=89)

2.
Get your special LightScribe media. When purchasing media, be sure to look for the LightScribe logo on the CD and DVD packages at your favorite retailers. You cannot burn LightScribe labels onto media without this logo.

Learn more about LightScribe-enabled CDs and DVDs. (http://www.lightscribe.com/products/index.aspx?id=106)

3.
Install the software if it's not installed already. Most LightScribe hardware products come with a CD with label-burning software. If you do not have the disc, you can purchase label-burning software online or at select retailers.

View a complete list of LightScribe labeling software (http://www.lightscribe.com/products/index.aspx?id=105). Or download a free version of Sure Thing 4 SE (http://www.lightscribe.com/support/index.aspx?id=307). LightScribe software includes two applications:

*
Labeling software. This is the program you'll use to create your labels. It may already be installed on your computer, or included on a disc with your hardware.

*
LightScribe System Software. Each hardware manufacturer will provide the optimal version for their systems, but you can also download a universal version (http://www.lightscribe.com/downloads/LS_Update_1.4.67.1_.exe) (XP ONLY). In some cases, the LightScribe System Software is included in the labeling application. Otherwise, it needs to be installed separately and may be on a separate disc than the labeling application.

Install your software by putting the disc into your disc drive and following the onscreen instructions. When the software is installed, remove the disc.

4.

Create your label design. If you have one of the following software programs, click the appropriate link for step-by-step instructions. Otherwise, continue reading for general instructions.

> Nero Cover Designer
> Roxio Easy Media Creator
> Sonic Express Labeler
> SureThing CD Labeler

General instructions:
If you're using stand-alone disc labeling software, launch the software and design the label onscreen by typing in your text, choosing or importing graphics, and arranging the text and images as you'd like them.

To get a jumpstart on your design, choose from the many backgrounds that have already been created for LightScribe labels. These designs are available in your LightScribe-enabled labeling software and in the label gallery.
5.

Burn the label. Place the disc in the drive with the label-side down. Then click "Print." After the label is burned, the disc will be ejected and your LightScribe CD or DVD is complete.

hehe... i still remember the old big floppy disk
floppy b or the 5 incher is obsolete.

floppy a or the 3 incher disk is still usable.

im still using it
for boot loaders. and dos programs.

[adijo13]

I had heard about 50 GB but 100 GB is quite incredible !!!!

Normal CDs give us Cyclic Reduction Errors, if 100 gb cds give us the same problem, ram ram satya hai..

[Leerz]

Normal CDs give us Cyclic Reduction Errors,
not really..................

[adijo13]

not really..................

If you write a CD over 685 MB, and then use it after 7-8 days, the data cannot be copied onto the computer unless u have a software...

I have experienced this a LOT of times, and I repent using CDs, Pen Drives aer better...:)

[shahidhanif0]

i think that is so big.
atlast the dvd is over.
and i think now the better quality of video can be recorded on it than dvd.

of course!
that is the recommended LIMIT! for standard burning
the Normal LIMIT
which you we're reffering earlier.

but since you've said If you write a CD over 685 MB
than that would surely happen.
Cd Medias, the outermost parts of the disk where last tracks and data are stored are prone to errors.
a physical error is what we can call it.

but if you have burnt your disk withouth exceeding the normal limit(or tne recommended limit)
than it's more likely that your data will still be safe unless you do something really nasty like bite the disk :rofl:

Companies would not have revoluttionized the use of the next generation media storage "the CD" (after the floppies and tapebacks-cassettes)
if your data will not be safe there :peace:

[adijo13]

of course!
that is the recommended LIMIT! for standard burning
the Normal LIMIT
which you we're reffering earlier.


That is what I didn't know earlier...

Anywho,now there is no question of writing CDs

Everyone deals in DVDs now:):peace:

Well i routinely write data of upto 700 MB (as close as it can get) & i never experienced this problem...

Nero always caches the files before burning & it doesnt give a problem..

I can directly copy my cds...

Which program do u use adijo for burning? & does it cache ur files before burning?

[adijo13]

Which program do u use adijo for burning? & does it cache ur files before burning?

I use nero...and yeah, it does cache files...
I have lost so much important data due to this problem...

I have even installed a Sony DVD-RW recently, but some CDs always get spoilt (mostly mp3s)...

[kronos*]

floppy b or the 5 incher is obsolete.

floppy a or the 3 incher disk is still usable.

yeah, i still remember the 5 inch floppy disk. my dad have an external super big floppy disk drive for that 5 inch disk(long time ago). but now its useless :D except for the floppy a. sometimes its usefull.

[tutusinghsohi]

well thats true that now-a-days people only deal in DVD's....
but that going to change as soon as the Blu-Ray hits the market.
here in the US, it has already been launched on 23rd May...
and the player for it will be released by SONY on close to 5th August...

[Leerz]

regular cd's are still alive pals ;)
