Non-rotating optical storage with adjustable mirrors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical storage technologies require rotation to read and write data, which can lead to mechanical stress and limitations in long-term, non-volatile, low-power, and low-cost storage solutions, especially in large-scale data centers.
Innovation Solution
A non-rotating optical storage system that uses linear movement of storage elements along the X and Y dimensions, facilitated by linear motors and optical access components, allowing adjacent bits to line up in straight lines rather than spirals, enabling robust, efficient, and cost-effective storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rotation is used to read and write data on optical storage media, then data access is enabled, but mechanical stress increases and reliability decreases for long-term storage
Solution Approach 1:
The patent extracts the rotation function from the storage media itself and relocates it to a separate scanning mechanism. The storage media remains stationary while a scanner with movable mirrors performs the scanning motion, thereby eliminating mechanical stress on the storage media while maintaining data access capability.
Solution Approach 2:
The patent introduces an intermediary scanning system with movable mirrors between the data access mechanism and the storage media. This intermediary performs the relative motion needed for data reading/writing without requiring the storage media itself to rotate, thus protecting the media from mechanical stress.
2Use of energy by moving object
If rotation is used for optical storage access, then data reading and writing are enabled, but power consumption increases
Solution Approach 1:
The patent extracts the high-power rotation motor requirement from the storage system and replaces it with a low-power scanning mechanism using movable mirrors. This maintains data access capability while dramatically reducing power consumption by eliminating the need to rotate heavy storage media.
Solution Approach 2:
The patent replaces the mechanical rotation system with an optical scanning system using movable mirrors. This substitution eliminates the need for high-power motors to rotate storage media, thereby reducing power consumption while maintaining the ability to access data across the storage surface.
3Quantity of substance
If spiral data arrangement is used on optical media, then continuous data access is enabled, but storage density and capacity are limited
Solution Approach 1:
The patent transitions from one-dimensional spiral data arrangement to two-dimensional grid-based arrangement. By organizing data in rows and columns that can be accessed independently through X and Y mirror movements, the system achieves higher storage density while maintaining access capability through the added dimensional freedom.
Solution Approach 2:
The patent introduces dynamic control of mirror positions in both X and Y dimensions, enabling flexible access to any data location in a grid arrangement. This dynamic positioning system replaces the fixed spiral path, allowing optimized data layouts and higher density while maintaining access efficiency through programmable mirror movements.

AI summary
Systems and methods for long-term non-volatile non-rotating optical storage of digital information rely on storage elements that include optical storage media, an access subsystem configured to access bits of information from one of the storage elements, and a support structure configured to support multiple storage elements. A laser used to retrieve and/or record bits of digital information may be moved along two orthogonal dimensions while the storage element is non-rotating.
