American scientists told about the new method of storing large data through CDs. This is reported on the company Optica.
Drive, which specialists call 5D is a CD (CD) created from quartz glass. According to the authors of the study, thanks to a new way, small carriers are capable of storing about 500 terabytes of data.
In scientific work it is said that each file recorded to the disk consists of three layers of nanoscale points. The size, orientation and position of the points in three standard dimensions are five “measurements”. The high density and capacity of the physical drive managed to achieve due to the use of lasers of ultrashort pulses, or femtosecond lasers.
Specialists created a “blank” to which five gigabytes of information were able to record. According to the authors, this is not the limit: using the new technology to the same CD you can save up to 500 terabytes of data. The recording speed is 230 kilobytes per second, that is, with a continuous parallel record, the disk will be filled in 60 days. The study states that the drive of this type could be useful in the data centers for backup.
Earlier it became known that in the video game market in the near future there may be a game of about one terabyte. The appropriate plans shared the head of the studio Haven Jade Reimond.
