optical disc

When a blank CD or DVD is handled by the Finder, a special burn folder is created for that disc which appears on the Desktop or in the Finder sidebar. Burn folders in OS X usually are static folders that remain until you remove them, but the ones representing optical discs should be created when the disc is inserted, and then destroyed when the disc is either ejected or burned. Despite this, some people may find that after managing a number of blank CDs or DVDs, the Finder will retain a few burn folders in the sidebar that are labeled &… Read more

Most optical discs are a standard 12cm in diameter, are round, and besides some potential manufacturing incompatibilities with certain optical drives, are expected to load and be recognized in most systems. Despite this, some companies will distribute device drivers or other content on mini or oddly shaped optical discs.

While the novelty of nonstandard discs is fun, it does pose a problem for many systems that cannot read them. While there is no difference in the way the discs are read, the odd shapes will get them stuck in many slot-loading drives seen in MacBooks, MacBook Pros, Mac Minis, and … Read more

While Apple has been on the blu-ray consortium for a few years, it has been reluctant to pursue blu-ray playback in the Mac OS. Meanwhile, Apple has been focusing on online delivery of HD content with the iTunes store; but even though the use of Blu-Ray movies is limited, you can still manage and use blu-ray disks on your Mac.… Read more

With Justin's return from his sojourn into the great outdoors, The 404 crew is complete again to bring you another awesome show, replete with "GI Joe" and "District 9" reviews, optical gaming, and a surprise appearance by Motherboard!

After getting mauled by a bear in Yosemite (where's the app for THAT?), I'm back, and much to Jeff, Wilson, and everyone else's dismay SO ARE THE GLASSES! That's right suckers, a little Krazy Glue goes a long way, but I'm not sure how long these things will last, so please continue to e-mail us submissions for the contest to choose my next frames. I'm not gonna lie, I've missed the show dearly and it's great to be back!

The first half of today's show has a lot of movie talk, starting with us talking all sorts of garbage on the new "G.I. Joe" movie. The movie won't be prescreened to critics, and we suspect it has something to do with the trailer receiving so much backlash from justifiably angry fans of the original television series. Jeff also gives us his take on the trailer for "District 9", the new science fiction movie based on the short film Alive in Joburg. Go check that out and let "G.I. Joe" go the way of the buffalo!

The second half just gets nuts, that's all I'll say. OK, well, without giving too much away, it all starts with the Get It Guy, a fake Australian accent, and a very steamy call from SadaCori in the chatroom (a must listen!), but then we get a surprise knock from Motherboard herself, who has something very special to show us...something that NOBODY HAS SEEN BEFORE, so be sure to check out the video for all the details. After that, we dredge up a claim about racism in Resident Evil 5 and it all devolves from there. Trust us, it's the last time you'll hear about it!

As always, feel free to leave us a voicemail at 1-866-404-CNET or get in touch with us on Twitter or at the404[at]cnet[dot]com!

A month after saying it had figured out how to squeeze 400GB of data onto a single optical disc, Pioneer says it can do better than that.

On Tuesday the company said that it is "feasible" to produce a Blu-ray-compatible disc with 20 layers. At 25GB per layer, that amounts to a 500GB disc. The previous claim of 400GB meant just 16 layers were on a single disc.

Blu-ray Discs are currently available in single layer (25GB) and dual-layer (50GB) discs.

The company said that it was able to squeeze more layers in by stacking alternating layers of … Read more

Got a big archiving project you've been itching to do? Pioneer's latest development could help you keep all your data in one nice, little circular package.

The Japanese electronics maker has been working on an optical disc, which, like Blu-ray, can store 25GB of data in a single layer. But Pioneer says it's one-upped the high-definition format to the sixteenth degree. The company announced today that it has a single disc that contains 16 layers of storage, at 25GB each. That adds up to 400GB of data capable of being stored on a single disc.

An Israeli start-up has created a way to store a whole lot of data on optical discs using fluorescence.

The TeraDisc looks like a regular CD, except it's chartreuse and see-through. Mempile says its disc will start off able to store 600GB to 700GB and in a year will be able to write 1TB worth of data. There are two physical layers of plastic, but 200 virtual layers on the one-sided disc. That means 250 hours of high-definition content or 300,000 digital photos. HD DVD and Blu-ray Disc can currently hold about 50GB of data on dual-layer discs. … Read more
