3,3TB optical drive from Sony

24.04.2016

Optical drives are becoming less and less common in personal computers, and it would seem that they will soon completely disappear into history. But they have their own niche in which optical discs are firmly established - movie studios and broadcast stations that need to store huge amounts of video, as well as large corporations that work with large amounts of rarely changed data.

For such customers, Sony has prepared a novelty - the second generation Optical Disc Archive cartridge with optical discs with a total capacity of 3,3 TB! Recall that the first CDs contained only 650 MB of data, the DVD capacity was 4,7 GB or more, and modern mass-produced Blu-ray discs can store more than 100 GB of information. By combining optical discs in cartridge format, storage capacities can reach several terabytes. New Sony not only has a record capacity, but is also characterized by twice the speed of reading and writing (due to the use of an 8-channel optical module) compared to the first generation cartridges.

At a price per GB, optical discs look more attractive than SSDs and hard drives, but with frequent writing and erasing, they wear out quickly and are not suitable as permanent media in a PC. Sony considers durability to be one of the advantages of its cartridges. The carriers used in them have a claimed lifetime of 1 years.

The new products introduced at NAB 2016 will support Everspan storage systems, which can be combined in hundreds of petabytes. The cartridge will go on sale this summer.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Mars Return Capsule 10.11.2013

Specialists of the European Space Agency (ESA) have created and tested a capsule for returning samples of Martian soil and air to Earth. The robust, multifunctional sample container is an important link in the long chain of unmanned missions that will bring soil and air samples from Mars to Earth.

The container, developed by ESA, is a 23-cm sphere weighing 5 kg, made of the strongest alloys. The container will need to keep the samples in perfect condition throughout the mission, maintaining a temperature of -10 degrees Celsius and maintaining a complete seal.

The mission will be unprecedentedly difficult. First, the sample container as part of the lander will land on the surface of Mars near the rover, which will load the container with carefully selected, most interesting samples. After that, the container with 10 soil samples and 1 air sample will be hermetically sealed.

The next step will be the launch of the apparatus with the container into the orbit of Mars, where in a few days it will be picked up by the orbiter. To simplify the rendezvous process, the container will be equipped with a radio beacon and a reflector for lidar (laser radar). Before being sent to Earth, the container will be placed in another, larger, protective sealed box, which will be dropped into the Earth's atmosphere. Since there is a possibility that the Martian samples may contain living organisms, the container will have the highest possible depressurization protection to prevent the samples from coming into contact with the Earth's biosphere.

Descent in the Earth's atmosphere will also be difficult. The ESA believes the parachute landing method is not reliable enough, so the sample container must withstand an emergency landing without a parachute, that is, simply speaking, a fall at great speed. The capsule will be braked not by a parachute, but by a heat-shielding aerodynamic screen.

At present, the container for a future Mars sample delivery mission is a proof of concept design, but the prototype has already successfully passed 400 g tests.
