Innovation Solution
A magnetic recording-reproducing head configuration with a first head section capable of both recording and reproducing processes, and one or more second head sections dedicated to erasing processes, but not reproducing, is implemented. This configuration includes specific magnetic pole layers and coils designed for efficient magnetic field generation and flux management, allowing for improved track erasure and re-recording capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single magnetic head is used for both recording and reproducing functions, then device complexity is reduced, but recording and reproducing characteristics become insufficient
Solution Approach 1:
The magnetic head is divided into distinct functional sections: a first head section with both recording and reproducing functions, and a second head section dedicated to erasing functions. This segmentation allows each section to be optimized for its specific function, improving overall recording and reproducing characteristics while maintaining manageable device complexity through modular design.
2Reliability
If a magnetic head for erasing is added to improve erasing function, then erasing capability is enhanced, but device complexity increases
Solution Approach 1:
The erasing head section is integrated with the recording-reproducing head section on the same support member, forming a unified head assembly. This merging approach enhances erasing capability while avoiding the complexity of completely separate head systems, as both sections share common mounting infrastructure and can operate in coordinated fashion.
3Reliability
If separate magnetic heads for recording, reproducing, and erasing are used, then functional performance is improved, but device complexity and space requirements increase
Solution Approach 1:
The first head section is designed with multi-functionality, capable of performing both recording and reproducing operations. This universal design reduces the total number of separate head components needed, thereby reducing the overall area required for the head assembly while maintaining high functional performance across all operations.
