• Laser‑written glass tablets can hold 2 million books’ worth of data for 10,000 years. • The technology uses femtosecond laser pulses to embed binary patterns in silica, creating ultra‑dense storage. • Glass offers exceptional durability, resisting radiation, heat, and chemical degradation better than magnetic media. • Data retrieval is optical, using a laser to read the encoded bits, enabling fast access. • The storage density reaches 1 TB per cubic centimeter, far surpassing current hard drives. • Project Silica aims to create a long‑term archival solution for cultural heritage and scientific data.

Article Summaries:

  • Microsoft’s Project Silica team has demonstrated a new data‑storage technology that embeds information in glass, allowing a single chunk to hold the equivalent of two million books and remain readable for up to 10,000 years. The system uses laser‑etched nanostructures to encode data in a durable, non‑volatile medium, offering a potential solution for long‑term archival needs. The development, highlighted in the latest Nature Podcast, underscores the growing interest in ultra‑stable storage formats that could preserve digital information far beyond current magnetic or optical media.
