sony\'s new tech could enable 185tb magnetic tapes

Sony has revealed details of future tape products that will be able to hold 185TB of data, equivalent to nearly 3,800 pairslayer Blu- Lei Pan, in the package of current size-day cassettes. According to the company, tape materials can store 148 Gb per square inch, the world\'s largest area recording density. The new tape can store 72 times more data per square inch than the current tape. Sony has achieved this by using a new soft magnetic underlayer on tape Scale particles can be deposited in a uniform crystal orientation. The process is carried out by using the \"sputtering method\" of the film. Electrostatic discharge forces ar ions to collide with magnetic substrates to form a thin film deposition of a data layer. The average size of Sony\'s new magnetic crystal is 7nm, while the current- According to the company, the size of the crystal is \"dozens of nanometers \". The main progress is to smooth the bottom layer with a thickness of less than 5 microns. This makes the crystals deposited by the vacuum sputtering deposition process more uniform and the size changes less. The surface of the existing tape is rough, resulting in non- Uniform deposition limits the range of increased density of development. The record of 148Gb per square inch is achieved during the experiment and it is still possible to improve further. Using the size of the standard LTO Ultrium cassette tape, Sony assumes that 185TB of cassette tape can be manufactured with this new material. This space is enough to store up to 1,184 160GB of ipod music ( This is something anyone can\'t hear in a lifetime) Although this type of final product will be targeted at large scale Extend the data center instead of personal use. LTO ( Linear Tape on) Cartridges are widely used for long- While similar tapes are no longer favored by consumer applications, term data archiving and backup are today. Due to the linear nature of the tape spool, the read-write speed is relatively low and the delay is large, so the cartridge is not suitable for direct storage or server applications. With LTO- 6. At present, the standard size of the cartridge can accommodate 2. 5TB. The cartridges themselves are relatively cheap, but the tape drives needed to read and write the cartridges can be very expensive. According to Sony, with the massive explosion of data stored in cloud storage facilities, constant backups become increasingly difficult to maintain, and customers still need to quickly restore their capabilities after any disaster. Organizations that need to transfer large amounts of data between locations can also use new products. Sony did not elaborate on any plans to launch a product based on its new technology, nor did it elaborate on the speed, capacity and price levels it might target. The company said further research on the materials was in progress, but there was no information on when the actual commercial product was available. This year, Sony and Panasonic announced a new archive disk format that allows 300 GB to be stored on a single disc. The plans require improvements to standards that allow 500 GB per disc, then 1 TB, while maintaining backward compatibility.
