Information Storage Systems [(Honma)-Greaves] Lab
Machine-translated · View original
A lab that explores high-capacity magnetic data storage through simulation.

AboutAbout the lab
Storing large amounts of data using magnetism.
The Information Storage Systems Lab studies high-density information storage based on magnetic recording and magnetic devices.
The amount of data generated as multimedia, IoT, and AI information is increasing rapidly every year, and storing it requires storage systems with high performance, large capacity, and low power consumption.
The lab models magnetic materials and devices using micromagnetic simulation.
It also studies magnetic devices for neuromorphic computing and probabilistic computing.
Key terms
- Micromagnetic simulation
- A method of reproducing the behavior of magnetic materials on a computer. For recording media, each magnetic grain of the medium is simulated one by one.
- Areal density
- The amount of information that can be stored per unit area of the recording surface. The higher it is, the more data can be stored in the same area.
- Neuromorphic computing
- A computing approach that imitates the workings of neural circuits in the brain. This lab studies magnetic devices used for such computing.
ResearchResearch themes
The lab's main interest is high-density information storage technology. It studies storage based on magnetic recording and magnetic devices, with the goal of fast, low-cost, high-capacity storage in which one bit of stored information occupies less than 100 nm² (an areal density of 10 Tbits/inch² or more).
