Multi-Spool Tape Mounts for Rapid Head Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic tape storage systems face challenges in access time due to the need to load and position tapes, which can take around 40 seconds, and the cost per unit storage is high compared to disk-based systems.
Innovation Solution
An apparatus with a receiving area for multiple tape spool pairs, a magnetic head, and a positioning mechanism that aligns the head with selected spool pairs, eliminating cartridge loading time and allowing a single head to service multiple spool pairs, reducing deployment costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cartridge-based tape library systems are used, then data storage capacity is improved, but data access time increases significantly (averaging about 40 seconds)
Solution Approach 1:
The system segments the tape storage by dividing it into multiple spool pairs, each capable of being independently accessed. This segmentation allows the magnetic head to quickly locate and access specific spool pairs without loading entire cartridges, thereby reducing access time while maintaining storage capacity.
Solution Approach 2:
The spool pairs are pre-positioned within the apparatus and kept in a ready state, eliminating the need for cartridge loading at the time of data access. This preliminary preparation of the tape spools allows for immediate data retrieval, significantly reducing the 40-second access time associated with traditional cartridge-based systems.
2Ease of manufacture
If multiple tape spool pairs are serviced by a single magnetic head, then deployment cost is reduced, but device complexity increases
Solution Approach 1:
The magnetic head is designed with multi-functionality to service multiple spool pairs sequentially. This universal head can read from and write to any of the spool pairs, reducing the need for multiple dedicated heads and thereby lowering deployment costs while managing complexity through a single versatile component.
Solution Approach 2:
The positioning mechanism is designed to be dynamic, allowing the magnetic head to move and align with different spool pairs as needed. This dynamic positioning capability enables a single head to efficiently service multiple spool pairs, reducing system complexity compared to having dedicated heads for each spool while maintaining cost-effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces data access time while maintaining economic viability, achieving faster data retrieval compared to traditional tape library systems and offering lower costs per unit storage compared to disk-based systems.
Implementation Method 1
The magnetic recording transducer then generates a magnetic field, which encodes the data into the magnetic media
Implementation Method 2
Data is read from the media by similarly positioning the magnetic read transducer and then sensing the magnetic field of the magnetic media
