Magnetic Tape Cartridge Winding Deviation Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic tapes used for data storage are prone to deformation during storage, leading to issues like overwriting and reproducing failures due to deviations in the magnetic head's position, especially as storage periods lengthen, necessitating a solution to maintain data integrity and accuracy.
Innovation Solution
A magnetic tape cartridge design with a minimum winding deviation occurrence load of 250 N or less, achieved by applying a tension of 0.30 N in the longitudinal direction during rewinding, which helps in minimizing deformation and maintaining the tape's stability, thereby ensuring accurate recording and reproducing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the magnetic tape is stored for a long period, then data archiving capability is improved, but the magnetic tape becomes easily deformed causing winding deviation
Solution Approach 1:
The invention changes the physical parameters of the magnetic tape by controlling the vertical squareness ratio to be 0.60 or more and the minimum winding deviation occurrence load to be 250 N or less. These parameter adjustments enable the tape to maintain dimensional stability during long-term storage while preventing winding deviation when subjected to tension forces during playback.
2Productivity
If tension is applied to the magnetic tape during running, then data recording and reproducing is enabled, but the magnetic tape may deform causing head position deviation
Solution Approach 1:
The invention modifies the mechanical properties of the magnetic tape by optimizing the vertical squareness ratio and minimum winding deviation occurrence load. These parameter changes allow the tape to withstand the tension applied during recording and reproducing operations without deforming, thereby maintaining head position accuracy within the data track while enabling normal data operations.
