Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data channels struggle to efficiently process data with varying signal characteristics across different storage mediums, such as magnetic discs and solid state memories, due to differing error correction needs and signal properties, leading to increased costs and complexity from dedicated channel components.
Innovation Solution
A multiuse data channel system with selectable components, including error correcting codes and detectors, is implemented, allowing the control circuit to dynamically select components based on data signal characteristics for optimal processing in different channel configurations, thereby reducing the need for dedicated components and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated channel components are used for each storage medium, then error correction reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal data channel capable of processing data from multiple storage mediums (magnetic discs and solid state memories) using a single integrated structure. The channel includes selectable components that can be configured to handle different storage medium types, eliminating the need for separate dedicated channels for each medium type while maintaining error correction reliability through medium-appropriate processing modes.
Solution Approach 2:
The data channel incorporates selectable components that can be dynamically included or excluded based on the detected storage medium type. The control circuit detects whether data comes from magnetic disc or solid state memory and accordingly activates the appropriate error correction mode, allowing the channel to adapt its complexity to match the actual requirements of each storage medium.
2Manufacturing precision
If dedicated channel components are used for each storage medium, then processing accuracy is improved, but manufacturing cost increases
Solution Approach 1:
By designing a single universal data channel that can process both magnetic disc and solid state memory data, the patent reduces manufacturing costs associated with producing multiple dedicated channels. The universal channel maintains high processing accuracy by incorporating selectable error correction components that are activated based on the storage medium type, ensuring medium-optimized processing without requiring separate hardware for each medium.
Solution Approach 2:
The patent changes the operational parameters of the data channel based on the detected storage medium type. The control circuit modifies error correction settings, detection methods, and processing modes according to whether the data originates from magnetic disc or solid state memory, allowing a single physical channel to achieve the processing accuracy of dedicated channels for each medium.
3Adaptability or versatility
If selectable components are included for all storage mediums, then adaptability is improved, but device complexity increases
Solution Approach 1:
The data channel employs selectable components that can be dynamically activated or deactivated based on the detected storage medium type. Rather than permanently including all possible error correction components for all medium types, the channel selectively enables only the necessary components for the current medium, achieving full adaptability while minimizing structural complexity through conditional activation.
Solution Approach 2:
The patent extracts only the necessary error correction components needed for each specific storage medium type and activates them only when required. The selectable components allow the channel to take out and use only the relevant error correction mechanisms for the current medium (magnetic disc or solid state memory), avoiding the complexity of permanently including all possible components for all medium types.
Data Source
AI summary
Presented is a data channel with selectable components, such as encoders or decoders. Also, data having different data signal characteristics can be processed through a data channel based on the data signal characteristics. Further, a data channel may have independent encoding path and an independent decoding path. For example, a first data transmission having first data signal characteristics may be processed via a data channel based on a first selected set of components of the data channel and a second data transmission having second data signal characteristics different than the first data signal characteristics may be processed via the data channel using a second selected set of components in the data channel. The first selected set of components may be different than the second selected set of components, but may share one or more common components.
