6 FAQs about [Optical disc energy storage]
What is optical nanoscale disk memory with petabit-level capacity?
Optical nanoscale disk memory with petabit-level capacity is developed by extending the recording architecture to three dimensions with hundreds of layers, and exabit-level storage can be achieved by stacking the disks into arrays.
Is optical data storage a viable solution for long-term archival data storage?
Optical data storage (ODS) presents a promising solution for cost-effective long-term archival data storage. Nonetheless, ODS has been limited by its low capacity and the challenge of increasing its areal density 4, 5.
Why are optical discs not widely used for big data storage?
As a matter of fact, optical discs have been sparsely used in current approaches to big data storage because their maximum capacity is limited to a few tens of gigabytes (GBs).
When do optical discs consume energy?
The data stored in optical discs does not consume any energy unless the information is written or read out during their lifetimes. In addition, this also tremendously reduces the operational and maintenance costs.
What is the maximum capacity of optical discs?
Optical discs have been sparsely used in current approaches to big data storage due to their maximum capacity being limited to a few tens of gigabytes (GBs).
How much energy is saved by using PB optical discs?
Using PB optical discs with nanophotonic approaches saves more than 70% energy in a single writing cycle. For comparison, the storage of one effective TB of information in PB optical discs consumes less than 0.3 kWh.
