Using high-speed lasers, researchers have created "5D" data storage technology that could allow 500 TB of data to be written to a CD-sized glass disc, according to the Optica society. The technique ...
SPhotonix is working towards commercializing its 5D optical "memory crystal" technology that uses lasers to write nanoscale data into durable fused‑silica glass. One 5‑inch disc can hold 360TB. The ...
