Blu-ray successor already in development?

Blu-ray successor already in development? Researchers from the Tohoku University, in conjunction with Sony have announced the active development of a "blue-violet ultrafast pulsed semiconductor laser" that will be used for disc storage.
Say the researchers: "This latest successful development is an all-semiconductor laser picosecond pulse source with a laser wavelength of 405 nanometers (1 nm = one-billionth of a meter) in the blue-violet region. It is capable of generating optical pulses in the ultrafast duration of 3 picoseconds (1 picosecond = one-trillionth of a second), with ultrahigh output peak power of 100 watts and repetition frequency of 1 gigahertz. Advanced control of the newly-developed and proprietarily-constructed GaN-based mode-locked semiconductor laser and semiconductor optical amplifier have enabled peak output power in excess of 100 watts to be achieved, which is more than a hundred times the world’s highest output value for conventional blue-violet pulse semiconductor lasers."

Additionally, "there are high expectations that this newly-developed semiconductor laser system, which incorporates semiconductor diodes, will be able to be used in a much wider range of applications in the future thanks to technology such as this, which enables the size of devices such as the light source box to be drastically reduced."

Sony says they will use the laser in next-generation disc storage devices, as the laser will allow for discs to hold up to 1TB of storage.

I, for one, would love to have full seasons of television shows on one disc.

Wow...1TB...that would be a nice disk format...it isn't like anyone has shown off a 1TB bluray disk...oh wait, they did! I think they even showed off a 100 layer disk with over 2TB of space...and it worked with current bluray players, or at least it worked with an unmodified PS3.

I guess this makes the 'Ultraviolet' storage locker's name a lot more logical.

only thing is this thing can hold a minimum of 1TB..so imagine a 2 TB dual layer

Not sure what you would use all of the room for. Nearly uncompressed video and audio? A slew of downloadable content already on the disc? That's ridiculous :O

I could put every digital thing (Games, docs, and a little bit of music is all I have) that I own on one of these.

how long will it be until the blank media is cheap enough to be worth buying though ? quite sometime me thinks

Ive got a 500Gb hdd in my computer and im only using 200GBs.arn't blu-ray movies like 8-15gbs???so probably a few hundred blu-ray movies.plus music,software,data,dvd rips and your kitchen sink LOL

custom built gaming pc from early 2010,ps2 with 15 games all original,ps3 500gbs with 5 games all original,yamaha amp and 5.1channel surround sound speakers,46inch sony lcd smart tv.

1 tb of data lost due to a tiny scratch and thanks to sony whom are the RIAA, MPAA, IFPI, FACT, CRIA all all the other scum front anti people compaines you were not allowed to make a back up as copying your own content according to Sony is criminal behaviour.

i think i'll keep passing these scum company offerings n stick to digital distribution until a pro consumer media is produced.. not one designed to remove our rights as the offerings that sony keeps touting..

That is a maximum of 1TB; not a minimum. Considering BluRay already has a maximum of over 2TB (shown working with current systems), this hardly seems like an advancement.

Clearly you don't own much digital media. I have about 1TB of "The Simpsons"...and I am no where near a complete collection.

What else would you use it for? How about seasons 1-10 of a TV show on a single disk? How about QFHD (3840 x 2160) in 3D? That is 8 times the needed bandwidth vs 1080P...or in other words, enough data to fill a DL bluray disk with a single 30 minute clip. I realize that such TVs are very rare and very expensive...but 1080P sets started out rare and expensive, and now you can get one for under $200. It is a given that bluray won't be around forever...and it is going to be a very long time before we see average internet speeds get close to what is needed for bluray quality streaming...so it only makes sense that they are developing (what might be) the last physical disk movie distribution format.

I actually may have typoed there in the article, it was unclear whether it was per layer or per disk for the 1TB limit. Will do some research.

Didn't Blu-Ray promise that? ;-)

I wonder how long it would take to burn these discs? A week?

A pulse every 3 picoseconds means this semiconductor laser has a frequency of 333333333333 Hz, or 333 GHz, or .333 THz. Cool.

They said it would be possible, but in practice, it hasn't been done too much because it is harder to charge $60 for the season when it is just one disk of SD content. For personal use, you can often put a whole season on one bluray...and if these disks really do start at 1tb, you could put 10-12 seasons of a show onto a single disk. Just don't expect to see 20 seasons of a show on 2 violetrays for sale at bestbuy.

Please all knowing killerbug show me where I can get a 1080p t.v for under $200

How mad would you be burning a full 1TB disc and in the final stages you created a coaster? I can only imagine what blank media will cost when first brought to market.

HEHE...yeah, that would suck big time...but what would be even worse? How about if you moved all your home movies to one violetray...and then it got cracked.

I'm sure blank violetrays will start out at least as overpriced as blank blurays started...so expensive that you can get the same space from high speed hard drives for less money.

I can still remember the days of 1x DVD burning. Where you'd get into 59 minutes of a 60 minute burn and it would crap out due to some buffer underrun error. So, you lost a then expensive DVD-R, you lost 59 minutes, and at least an additional 60 minutes to reburn the failed attempt.

You can compress them down to about 10 Gb. So your disk would hold 50 not 100.
