Hitachi Push Quartz Glass data storage technology can store data permanently

This storage technology storage unit is 2 cm long by the side, 2 mm thick square quartz glass, each square inch can store 40MB of data, the data is through the laser on the quartz glass point in accordance with the four-layer structure in binary format to burn, can be used in ordinary optical microscope reading. Hitachi says it can increase storage capacity by adding more layers to the storage unit.

"The amount of data that people create on a daily basis is exploding, but in terms of data preservation our technology is not improving and the likelihood of data loss is growing," said a Hitachi researcher. Users must have a wealth of experience, or they may encounter problems that cannot recover lost data. ”

Hitachi said that even if the quartz glass in the environment of 1000 degrees Celsius two hours, the data stored on the above will not be destroyed, in addition, quartz glass storage can also prevent radiation, waterproof and prevent a variety of chemicals.

Hitachi has yet to decide whether to actually configure a chip to use the technology, which could initially be used in the data storage services of government departments, museums and religious organizations.

Currently, this storage technology uses a material with four layers of laser spots, each square inch of data storage of 40MB.
