Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic recording media face challenges in increasing storage capacity and reducing size while maintaining thermal stability, as higher bit density leads to decreased signal-to-noise ratio and increased susceptibility to information loss due to thermally activated magnetization reversal and adjacent track interference.
Innovation Solution
A three-dimensional storage device using a system with a data storage medium and a shockwave generator, where information is stored electrically by altering electric field orientations and intensities within cells using lasers, allowing for precise writing and reading without affecting other cells, and maintaining information after the shockwave signal passes through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If bit density is increased to store more information, then storage capacity is improved, but signal-to-noise ratio deteriorates and susceptibility to thermal erasure increases
Solution Approach 1:
The patent transitions from two-dimensional magnetic bit storage to three-dimensional electric field storage. Multiple storage cells are arranged in vertical stacks across multiple layers, enabling data to be stored in the third dimension (depth). This dimensional change allows increased storage capacity without reducing the lateral size of individual storage units, thereby maintaining signal-to-noise ratio and thermal stability.
2Quantity of substance
If bits are made smaller to increase density, then storage capacity is improved, but thermal stability deteriorates
Solution Approach 1:
By stacking multiple storage cell layers vertically, the system achieves higher bit density through the third dimension rather than reducing the size of individual cells. Each storage cell maintains its original lateral dimensions and thermal stability characteristics, while the overall density increases due to the multi-layer vertical arrangement.
Solution Approach 2:
The patent replaces magnetic field-based storage with electric field-based storage. Instead of relying on magnetic moment orientation that is susceptible to thermal fluctuations, the system uses electric field orientations within storage cells. This substitution provides enhanced thermal stability because electric dipoles in the storage cells are less susceptible to thermal activation compared to magnetic moments.
3Quantity of substance
If bits are packed closer together to increase density, then storage capacity is improved, but adjacent track interference increases
Solution Approach 1:
The patent eliminates adjacent track interference by transitioning to three-dimensional storage with vertically stacked layers. Each storage cell in a vertical stack is electrically isolated from its neighbors through the shockwave excitation mechanism and electrical insulation between layers. This allows dense packing without interference because the excitation and readout processes are localized to specific vertical positions within each cell.

Function Achieved in This Case
This approach enables increased storage capacity and thermal stability by allowing for higher bit density without degrading signal quality, as the electric field orientations and intensities can be precisely controlled and maintained within the cells, enhancing data retention and retrieval.

Data Source
AI summary
A system includes a data storage medium and a shockwave generator. The data storage medium includes cells and a plurality of layers. Each cell is configured to store information therein. At least two cells are arranged in a horizontal plane within a same layer of the plurality of layers of the data storage medium and at least two cells are arranged in a vertical plane in different layers of the plurality of layers of the data storage medium. The shockwave generator is configured to generate a shockwave signal that travels through a layer of the plurality of layers of the data storage medium. A target cell within the layer stores information responsive to a beam emitted from an emitter targeting the target cell as the shockwave signal is passing through the target cell. The target cell maintains the information after the shockwave signal exits through the target cell.
