IFA - TDK develops prototype 200G Blu-ray disc

Japan's TDK has developed a single-sided recordable blue laser disc with a capacity of 200G bytes.

In the battle of new optical storage formats, Blu-ray Disc has added another weapon -- even more storage.

Japan's TDK has developed a prototype single-sided recordable blue laser disc with a capacity of 200G bytes, surpassing the current 25G-byte capacity for single-layer Blu-ray discs and 50G bytes for dual-layer discs, the company announced at the IFA consumer electronics show in Berlin.

TDK had previously developed a prototype disc with a capacity of 100G-bytes. The latest prototype will store approximately 18 hours of high-definition video.

TDK didn't say when the discs would be available.

Several Hollywood film studios announced on Thursday the release of numerous titles on the Blu-ray Disc format, to be available ahead of the holiday shopping season in December.

Windows 10 for Business / Dell XPS

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
