Sanyo Blu-ray Laser Brings 12x Burning On 100GB Discs

It has been a fairly unrewarding process advancing the cause of Blu-ray burners. It has taken an age for write speeds to increase and they still remain prohibitively expensive for many. So thank heavens for Sanyo...

The Japanese giant has announced today that it has come up with a way of boosting Blu-ray burn speeds to an altogether more potent 12x and over no less than four layers (meaning on potential 100GB discs written in under 10 minutes). Current drives tend to top out at 6x (though 8x models are appearing) and are limited to dual layer 50GB discs.

The snag in all this (there's always a snag) is the laser required emits a beam of 450 milliwatts, roughly twice that of existing solutions and means it will have to be ratified by the Blu-ray Disc Association (BDA) which must then create a new standard before any hopes of a mass market roll-out. Given the complexities of this we may not see Sanyo's breakthrough for between one and two years and even then it's not going to be cheap.

Still, it must be argued that like DVD archiving, Blu-ray storage will likely become a niche market which has arguably already been overtaken by cheap external HDDs and ever larger memory keys. Sure it is nice to burn discs for playback on an HDTV but unless it is home shot HD footage chances are you're doing something a bit naughty, while HD on demand is becoming an ever more viable solution with each passing quarter.

Do you think disc burning has already had its day, or is it still a viable (if scratch prone) long term solution? Let us know...

I think CD/DVD have had thier days. First, a tiny bit of scracth destroys an entire disc. It is very slow to write; you can only write once (or add bits later to empty space, but you can't delete and reuse a disc) and it is very expensive. The most important part of a cd/dvd is the surface where data is recorded, yet the mechanism of cd/dvd is such that this surface is always exposed to scratch and dirts unlike a tape/vhs, or even a floppy disk, where the "data holding part" of the product is safely hidden. Frankly, I don't know an absurd idea like cd/dvd ever got commercialised so successfully!

I think, given that to store files on a harddrive all you need is a harddrive, optical storage has had its day. With optical disks you need the burner, and the software, and the blank media, and the pens to write on the disks, and then you need to store the disks, keep them safe, then find which disk you want, blah blah blah.

With a harddrive all of your data is one place, it's searchable, it's safe and secure.

I appreciate that people like physically owning CDs/DVDs because they can look at the box art, or take it to a friend's house, or read the inlay - but those people are usually people who started in the consumer market by buying CDs. When you buy a CD it's only going to get transferred to a HDD anyway, to go on an iPod or whatever.

You can get album artwork on iTunes. You can purchase full albums on iTunes, some of which are really hard to find in stores, cheaper than CDs are in store, and much quicker. I just don't really see optical disks making a come back.

All you need to be able to do is go to a shop with a USB stick to purchase a movie, which you transfer onto a player that's plugged into your TV - or purchase a download, and digital distribution will soon take over. Apple TV is already doing well - and we all know how popular movie piracy is.

"The most important part of a cd/dvd is the surface where data is recorded"

Not true - data is stored in the metal layer sandwiched between protective plastic. Besides, if you consider a jewel case as the container for the disc, it's little different to a floppy.

"Frankly, I don't know an absurd idea like cd/dvd ever got commercialised so successfully!"

You are aware of when the CD was commercially introduced, aren't you? Of the contemporary digital storage capacities?

Optical storage has lagged behind the capacities of magnetic storage for some time now. Solid-state drives are coming up hard on the rails. Still, for the physical distribution of data I'd imagine that optical has a bit of life in it yet.

You can buff the surface of a cd, dvd or (i presume) Blu-ray disc with a little brasso to get rid of scratches. And if the metal surface begins to deteriorate, it's usually in discrete places, meaning most of the data is still recoverable with freely available software.

However, if you hard drive fails, getting the data off it can be very expensive! Likewise with flash memory.

I like CDs for their permanence.

There's plenty of freely available software for recovering data on a HDD ;)

Azad: It was tried, DVD-RAM disks were initially sold in floppy disk style cases but it didn't take off and now they're just sold as disks without the cartridge.

I've only had one hard-drive fail on me (that was a long time ago), whereas I've had numerous problems with CDs. I can't see another generation of optical disk media appearing for anything other than business or console use. By the time the new burner format is ready people will be used to recording onto HDDs. Why not? The cassette gave way to the CD for it's improved storage, performance and reliability and the same will happen here. As a bonus it'll cut down on plastic production and carbon emissions - a new generation is emerging... of green technophiles (who should boycott Starbucks btw, until they agree to turn off their taps).

I agree with a lot of the above, but theres still not a cheaper way for the consumer to send 8.5GB of data easily to someone else. how much is a decent branded dual layer DVD ? 50p each (roughly) if u buy them in one of those large cake things. Then to post it to anywhere in the uk (example), less than 50p ? And if it gets lost or broke in the post who cares.

Anyway, with memory cards / usb sticks etc crashing in price all the time, they are definately taking over. I think an 8gb SD card can be had for less than a tenner.

Though what the hell is the deal with blank Blu-Ray discs ???!!?!!?! &#16317+ for a Dual Layer ! Are they mad ! Thats like more than a movie ! Plus the blu-ray burner &#163150+. They aint bending me over for the cash !

Anyways, im off to do some DVD-RW burning at x4 speed. Who needs usb pens and hard drives :-P

Not me. I just have a room full of children I force to memorise numbers.
