Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tape storage devices suffer from long addressing times, limiting their application scope due to low timeliness performance, and reducing tape length to improve access time compromises storage density and capacity, increasing costs.
Innovation Solution
The tape storage apparatus is designed with multiple tape assemblies arranged in intersecting directions, utilizing a driving component and magnetic head component to facilitate efficient addressing, and incorporating actuating components to move the magnetic head across the assemblies, allowing for reduced addressing duration without compromising storage capacity or density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If tape length is reduced to improve addressing time, then access performance is improved, but storage density and capacity are compromised
Solution Approach 1:
The patent transitions from a single-dimensional tape arrangement to a multi-dimensional configuration by arranging multiple tape assemblies in the first direction (intersecting the rolling direction). This spatial reorganization allows the system to maintain shorter tape lengths for improved addressing while compensating for reduced capacity through increased tape width and multiple assemblies, effectively utilizing three-dimensional space for storage.
Solution Approach 2:
The patent divides the storage system into multiple independent tape assemblies, each with its own reels and tape. This segmentation allows each tape to be shorter (improving addressing time) while the collective system maintains high storage capacity through the aggregation of multiple assemblies. The magnetic head component can selectively access different tape assemblies, providing both fast access and high overall capacity.
2Loss of time
If tape length is reduced to improve addressing time, then access performance is improved, but storage density is compromised
Solution Approach 1:
The patent compensates for reduced tape length by expanding into the width dimension. Multiple tape regions are arranged in the third direction (width direction), and the tape width is increased to accommodate more data tracks. This dimensional expansion maintains storage density despite shorter tape lengths, as the increased width compensates for the reduced length in the rolling direction.
Solution Approach 2:
The patent implements different tape configurations for different functional requirements. Some tape assemblies are optimized for fast access (shorter length) while others provide bulk storage capacity. The magnetic head component can be positioned at different locations along the tape width to access specific regions, allowing the system to optimize local areas for either speed or density based on operational needs.
3Loss of time
If multiple magnetic heads are added to improve addressing capability, then access performance is improved, but device complexity and costs increase
Solution Approach 1:
The magnetic head component is designed as a multi-functional unit that can access multiple tape assemblies through the first actuating component. Instead of having separate magnetic heads for each tape assembly, a single magnetic head component serves multiple purposes by moving across different tape assemblies in the first direction. This reduces the total number of magnetic heads while maintaining the ability to quickly access any tape assembly.
Solution Approach 2:
The first actuating component serves as an intermediary mechanism between the magnetic head component and the tape assemblies. It enables the magnetic head to efficiently move to different tape assemblies without requiring multiple fixed magnetic heads. This intermediary actuation system provides flexible addressing capability while keeping the number of magnetic heads minimal, thereby reducing device complexity and cost.
