Cerabyte wants to kill off magnetic tape by 2030 using ceramic lasers and some wild physics


  • The first-generation system is slower than tape but aims to scale up rapidly by 2030
  • Cerabyte’s roadmap involves physics so advanced it sounds like sci-fi with helium ion beams
  • Long-term capacity hinges on speculative tech that doesn’t yet exist outside lab settings

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.
