Graphene will increase the volume of the HDD tenfold

Published

Researchers at the Cambridge Graphene Center have shown that graphene can be used to create ultra-high-density hard drives, providing a tenfold jump over current technology.

The study, published in Nature Communications, was conducted by British researchers in collaboration with colleagues from India, Switzerland, Singapore and the United States.

Hard drives, which have been widely used in personal computers since the mid-1980s, have become smaller in this time, but significantly more spacious. Although they are being crowded out by solid state drives, hard drives are still popular for their lower cost.

The increase in volumes is associated with an increase in recording density, in turn, provided by the improvement of two key components: the platters and the head. In particular, developments that made it possible to reduce the gap between them.

Currently, a significant part of this gap is occupied by carbon-based coatings – layers designed to protect the plate from mechanical damage and corrosion. Since 1990, the recording density has quadrupled and the coating thickness has decreased from 12.5 nm to about 3 nm. These parameters correspond to a density of 1 terabyte per square inch.

Researchers from Cambridge replaced the currently used coatings with graphene (one to four layers) and tested friction, wear, corrosion, thermal stability and compatibility with lubricants. In addition to its unsurpassed fineness, graphene has proven to have all the ideal outer coating properties for hard drives in terms of corrosion protection, low friction, wear resistance, hardness, lubricant compatibility, and surface smoothness. It cuts friction in half and provides better corrosion and wear protection than current solutions. In fact, one layer of graphene reduces corrosion by 2.5 times.

The scientists also tried out locally heated media recording (HAMR), a new technology that can increase storage density. Unlike graphene, currently used coatings do not operate at the temperatures required for HAMR. Graphene, when combined with HAMR, is said to increase the recording density to an unprecedented level of over 10 terabytes per square inch.

Scientists do not say how soon the development will come to serial HDDs.

The Honor 70 Pro features a 6.78-inch OLED screen with a resolution of 2652 x 1200 pixels and a 4500mAh battery with 100W charging support. At the heart of the hardware platform is the SoC MediaTek Dimensity 8000 with performance roughly on par with the Snapdragon 888.

Honor 70 Pro received a 50-megapixel front camera and a main one with sensors with a resolution of 54 (this is a Sony IMX800 with an optical format of 1 / 1.49 inches), 50 and 8 megapixels. The latter provides a 3x optical zoom.

Virgin Orbit successfully launched a LauncherOne rocket carrying seven NASA

Virgin Orbit launched a seven-satellite rocket from California’s Mojave Aerospace Port on Saturday, marking the company’s first successful overnight mission. Virgin Orbit launched satellites into low Earth orbit using its Boeing 747 carrier aircraft called Cosmic Girl, which had a LauncherOne rocket attached to it.

The mission, named Straight Up after a song by Paula Abdul, involved the launch of seven NASA research satellites. As in previous missions, the launch of the rocket took place from a height of 10 km, which climbed Cosmic Girl. The carrier plane’s flight was originally scheduled to take place on Thursday, but Virgin Orbit postponed the mission after experts found LauncherOne’s propellant temperature was “slightly out of range.”

In total, Virgin Orbit has already carried out five launches, four of which were successful (only the first test was unsuccessful). Virgin Orbit is owned by British billionaire Richard Branson, but should not be confused with Virgin Galactic, the company’s separate commercial spaceflight division.

XMAGE camera periscope module and 7x optical zoom Huawei Mate

The premiere of the Huawei Mate 50 series smartphones is expected on September 12 – not soon, but renders have already begun to be published on the Web, which are based on leaks and images of cases. These pictures show perhaps the highest quality concept renders of the Huawei Mate 50 Pro. Moreover, the smartphone poses in two colors at once – black and white.

The main thing here, of course, is the camera. The block contains the name of the new corporate brand of the camera – XMAGE. It will combine all the old and new technologies of Huawei in the field of mobile photography. XMAGE is a synthesis of two words, Extreme and Image, and under the brand, Huawei will focus on three pillars: photography experience, culture, and innovation. That is, it will be more than just a set of sensors and lenses.

But we are more interested in technology. Judging by the inscriptions in the camera block, the smartphone will have lenses with a focal length of 13 to 90 mm, that is, we can talk about a 7x zoom. The main module will most likely have a wide-angle lens. And 90 mm is the focal length of the lens of the periscope module. Of course, there will be optical stabilization.

Huawei novelties are also credited with SoC Snapdragon 8 Gen 1 and Kirin 9000s, 8 GB of RAM and 128-256 GB of flash memory. These models will be the first to run HarmonyOS 3.0 out of the box.
