  • TDK develops 1TB optical disc, leaves other optical storage feeling emasculated

    We've heard about 1TB-sized optical discs in the past, but TDK has now revealed a 1TB monster of its own at CEATEC. Unlike existing Blu-rays which use four recording layers at most, TDK's creation features 16 layers on both sides of the disc, each capable of storing up to 32GB apiece. If you're keeping track of the optical storage arms race, that's seven more gigabytes per layer than Pioneer's 400GB and 500GB disc achievements made back in 2008. TDK's prototype also has the potential to leverage existing Blu-ray technologies, since it's made from a material already found in BDs and shares the same beam aperture. On the down side, the current version's recording layers measure 260μm -- that's more than twice as thick as its Blu-ray counterpart -- and causes aberrations in today's fat-layer-hating optical lenses. Outside of its Biggest Loser qualifications, though, TDK says "its commercialization depends on disc manufacturers." Considering the company has yet to sell the 10-layer 320GB discs revealed at CEATEC 2009, however, we're doubtful this 1TB improvement will hit stores anytime soon.

  • Sony Optiarc garners unwanted attention from DOJ for possible Blu-ray or DVD price fixing

    In a filing with the Tokyo Stock Exchange this morning, Sony has revealed a request for information from the US Department of Justice regarding its optical drive production arm, Sony Optiarc. While the same filing indicates the Japanese giant's belief that this information gathering is part of a wider investigation into competition in the optical drive market, we've yet to hear of any other companies facing the same request. If you were feeling disgruntled with the pace of Blu-ray price drops, this might just be your moment of vindication... or it could be a storm in a teacup. There's really not enough information to tell either way right now, but if we know anything about the DOJ, it's that it loves shaking down naughty corporations. We'll keep a careful eye on this as it develops.

  • Super-size Three: PS3 can read Pioneer's 16-layer, 400GB Blu-ray Discs

    16 layers. 400 giga ... bites? Sounds like the fast food burrito equivalent of the Death Star. Ah, but it's not. It's a Blu-ray Disc, and those are gigabytes. So, this massive (current dual-layer BDs hold 50GB), entrancingly translucent disc? PS3 is compatible with it.Thank goodness. This will hopefully put an end to the flood of multi-BD games on the system. This disc, suitable for use by Tron, was first revealed this summer by its creator, Pioneer, and will be available en masse in 2010. Good news for those with large ... image collections: a writable version of this jumbo jet of Blu-ray Discs is also in development.[Via PS3 Fanboy]

  • Sony demos "cheap" holographic recording technique

    Ever since we first laid eyes on a holographic sticker as small children, we knew that this technology would change the landscape of data storage forever (not really, but it makes for a good story), and now Sony has come along and introduced a new way of burning holographic discs that will supposedly expedite the rollout of these magical drives to the average consumer. At this year's International Symposium on Optical Memory taking place in the Kagawa Prefecture of Japan, Sony is showing off its "Micro-Reflector recording" technique which uses an off-the-shelf blue violet semiconductor laser diode for writing data to a 0.3 millimeter-thick photopolymer medium sandwiched by 0.6 millimeter-thick glass substrates without any of the spatial light modulators or CMOS sensors found in traditional holographic systems. How do they achieve this nifty feat, you ask? Simple: the laser beam is "split into two so that one of them irradiates the front side of a medium as a reference light while the other is emitted to the backside as a recording light. By precisely aligning focal points of the two lights with a servo technology, a minute interference fringe corresponding to a 1 bit recording mark is formed. When a laser light (reproduction light) is emitted on the front side of the medium having interference fringes, the recording light is reproduced. This light advances from the fringes to the medium front side as if the fringes reflect the reproduction light." It's all so obvious when you think about it, we're surprised that companies like Optware and InPhase didn't come up with this method first.

  • Cima Lab's new DVD player rocks DivX, card slots, and USB

    We remember when $70 wouldn't even buy you a decent VCR, but oh, how times have changed. With upscaling DVD players -- not to mention next-gen optical formats Blu-ray and HD DVD -- currently all the rage, now that same $70 will buy you a device that not only plays DVDs but features memory card slots and a USB port as well. Coming in September for about 7,980 yen ($68 -- why, that's even less than 70 bucks!), the CDP-200UCR from Cima Laboratory will happily spin all of your plain jane DVDs and CDs, but ups the ante by including DivX, MP3, and WMA support as well. You're also getting 5.1 analog audio, an integrated card reader with SD / MMC, MemoryStick, and yes, even SmartMedia slots (do they even sell that format anymore?) plus a front-panel USB jack for piping in content from compatible devices. Sure this player may never make it Stateside, but its nice to know that our friends in Japan have all their bases covered.

  • Protein-coated discs could enable 50TB capacities

    We know that it shouldn't come as a shock anymore when researchers announce new storage technologies that promise to hold tantalizingly large amounts of data, but we were still pretty stoked to learn that a recent breakthrough at Harvard Medical School may eventually lead to DVD-size discs whose capacities approach an eye-popping 50TB. Unlike traditional optical or magnetic solutions, the disc developed by Professor V Renugopalakrishnan and his colleagues is coated with thousands of light-activated proteins called bacteriorhodopsin which are found in the membrane of a particular salt marsh microbe -- and which temporarily convert to a series of intermediate molecules when exposed to sunlight. That property allows the proteins to act as individual bits in a binary system, but since they have a tendency to return to their grounded state after mere hours or days, Renugopalakrishnan and his team modified the requisite microbes' DNA to produce proteins capable of maintaining that intermediary state for several years. Unfortunately we won't see this technology come to market anytime soon, and even when it does, 50TB capacities will still be a ways off, so it looks like we'll have to settle for those disappointing 200GB Blu-ray discs for the foreseeable future.[Via Gotakon]

  • Samsung BD-P1000 Blu-ray player delayed (again)?

    In what may turn out to be yet another crushing blow to HD-hungry consumers, it looks like Samsung could be joining Sony, Pioneer, and, um, itself, in playing the Vista-like Blu-ray delay game that continues to amuse and frustrate us. As of right now, the facts are these: UK tech site Pocket-Lint sent an email to Bite Communications, Samsung's British PR firm, in order to confirm what we all thought was the BD-P1000's June 25th release date; instead of a confirmation, however, Pocket-Lint received a surprising reply stating that "unfortunately, the release of the Blu-ray has been delayed until September." Before you start freaking out, though, keep in mind that at this point details are still very thin -- we can't even be certain if this supposed delay applies to the US launch, or only affects our friends over in Great Britain. As you'd expect, we have our crack team of low-paid interns furiously dialing every Samsung representative we can find a number for, and you'll be the first to know when we can finally pin someone down on a solid release date, so stay tuned.Update: Whew, good news (well, for us Americans at least). Samsung has confirmed that the US launch is still "on schedule," although Bite was right on the money about the UK delay, so as usual, Brits are gonna have to wait a little longer to get a hot new product.
