Actuated Media Player for Fast Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data storage systems face challenges in providing fast and cost-effective access to large volumes of data, with online systems consuming high power and maintenance disrupting system operations, while offline systems suffer from slow data access due to tape retrieval delays.
Innovation Solution
A mass data storage system utilizing robotic actuation to move a media player relative to storage cartridges on a rack-type library, allowing read/write operations without moving individual cartridges, thus achieving faster access times and maintaining competitive build and operating costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If online storage systems are used to provide fast data access, then data access speed is improved, but power consumption increases significantly
Solution Approach 1:
The system dynamically transitions storage media between online (accessible) and offline (inaccessible) states based on access requirements. The media player can quickly access online data while less frequently accessed data remains offline, providing dynamic adaptability between speed and energy consumption states
Solution Approach 2:
The storage system segments data into online and offline portions, with the media player capable of accessing specific segments as needed. This segmentation allows fast access to frequently used data while keeping other data offline to conserve energy
2Use of energy by moving object
If offline tape storage systems are used to reduce power consumption, then energy efficiency is improved, but data access speed deteriorates due to tape retrieval delays
Solution Approach 1:
The system dynamically transitions storage media between online (accessible) and offline (inaccessible) states based on access requirements. The media player can quickly access online data while less frequently accessed data remains offline, providing dynamic adaptability between speed and energy consumption states
Solution Approach 2:
The system performs preliminary actions by pre-positioning the media player and pre-loading required data onto accessible media before actual data access is needed. This eliminates tape retrieval delays by having the media already in position and ready for immediate access
3Ease of operation
If traditional storage systems with separate read/write electronics are used, then data access functionality is maintained, but system complexity and maintenance requirements increase
Solution Approach 1:
The patent merges the read/write control electronics with the media player into a single integrated unit. This consolidation reduces the number of separate components, simplifies the system architecture, and decreases maintenance requirements by eliminating the need to service separate electronic components
Solution Approach 2:
The integrated media player incorporates multiple functions including reading, writing, and control electronics within a single device. This multi-functionality reduces overall system complexity by eliminating the need for separate dedicated components for each function
Data Source
AI summary
A data storage library includes multiple storage cartridges arranged in a rack; read/write control electronics integrated within a media player assembly; and actuation means for achieving relative movement between the media player assembly and the multiple storage cartridges in the rack to allow the read/write control electronics within the media player assembly to selectively couple with and provide data access to at least a subset of the multiple storage cartridges.
