Three-Dimensional Magnetic Recording Device

摘要

In the course of this proposal, it is proposed to develop and simulate a thermally-stable one-thousand-layer 3-D recording system with an eight-bit address/word line capable of recording and retrieving eight bits in parallel. Assuming a bit cell with one square micron in cross-section, this is equivalent to an effective areal density of 640 Gbit/in2. The undergraduate student involved in this proposal (Nissim Amos) and the PI will make a presentation of the results of the numerical simulations indicating the functionality of the device. The simulations proposed will be performed both with PC and a state-of-the-art computer cluster system recently established at FIU. The use of the cluster computing will allow to extend the simulations (in the near future) to systems capable of pentabyte recording. The simulations will incorporate both magnetostatic and micromagnetic (quantum-mechanical) interactions between the grains in the 3-D media. The thermal stability of the recording media will be addressed throughout the simulations. In the course of this proposal, it is planned to raise interest in this technology at least to the level of prototype building. A detailed plan (with drawings and steps) to build a first-principle prototype will be proposed by the end of the project. In the course of this proposal, it is planned to publish at least two articles (one on the modeling technique and the other on the simulation results) in peer- review journals (upon an agreement with US Air Force). The above-described project on simulation of a 3-D magnetic recording system will be conducted in parallel with the experimental work on the prototype development.
