Cerabyte wants to kill off magnetic tape by 2030 using ceramic lasers and some wild physics
Munich-based startup Cerabyte is developing what it claims could become a disruptive alternative to magnetic tape in archival data storage.
Using femtosecond lasers to etch data onto ceramic layers within glass tablets, the company envisions racks holding more than 100 petabytes (100,000TB) of data by the end of the decade.
Yet despite these bold goals, practical constraints mean it may take decades before such capacity sees real-world usage.
