1TB optical disks now in prospect

Manufacturers are being offered 1TB optical storage technology to license

Manufacturers are being offered the world's highest capacity optical storage technology to license, reportedly, leap-frogging 300GB holographic disks and offering 1TB in a DVD-size disk. But the technology has not been commercialized and product could be three to five years away.

It uses a 2-photon recording process to record bits in a three-dimensional inside a disk's recording media coating. Multiple layers of information can be stored within the 3D volume with less than a 10-micron layer of separation. This effectively allows the equivalent of 250 conventional DVD layers to be put onto one disk platter. The roadmap lays out fivefold capacity increase through greater layer densities. This could enable a disk to store high definition format movies.

It could also enable movies or equivalent data up to 50GB to be stored on 1-inch optical disks inside PDAs and mobile phone-format devices.

Call/Recall says that another advantage of its technology is its use of affordable, commercially available, off-the-shelf components. This approach allows optical hardware manufacturers to extend the roadmap of their existing technologies, such as DVD and Blu-ray Disc, while maintaining backward compatibility with their installed base. Additionally, other key components are designed as molded/replicated parts, enabling low-cost production on industry-standard production lines.

Call/Recall is a military- and commerce-funded very high capacity optical storage research company. A co-founder is Dr. Peter Rentzepis. He is a former head of Bell Laboratories and, according to the company, a world-renowned scientist who has authored approximately 85 patents; his innovations are referenced as prior technology by 45 of the world's top optical technology providers, including IBM, Panasonic and Hitachi. This gives the technology more credibility.

One storage research analysis has offered an opinion on it. ESG analyst Heidi Biggar said: "Advances in optical technologies, such as Call/Recall's 2-photon 3D technology which promises to offer multiple terabyte data capacities and significantly faster data access than tape, hold new promise for users as they look to build more efficient and effective archives."

This is not exactly fulsome as the same sentiments could be applied to future InPhase holographic disks and blue laser UDO disks from Plasmon. In fact, the delay before any commercialization could give InPhase with its holographic Tapestry disks time to deliver on its terabyte disk roadmap. Plasmon's UDO should also be in the terabyte area by then.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

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.
