The advantages over current magnetic tape storage media include greatly increased durability and longevity, since quartz glass can withstand extreme temperatures and does not react to water. Additionally, the glass sheets offer improved scalability and reduced maintenance, plus simplified data retrieval through femtosecond laser encoding and machine learning algorithm decoding.
