Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording heads lack an effective method for accurately adjusting angular deviation in the rotation direction within the plane parallel to the recording surface, leading to potential image defects due to small angular deviations in the head module's rotation, which are not adequately addressed by current mechanical adjustment techniques.
Innovation Solution
A recording head system comprising a head module with a rotation direction adjusting unit, including a rotation support mechanism and a second direction moving mechanism, along with a position detection unit, allows for precise adjustment of angular deviation within the plane parallel to the recording surface, using a simple configuration that includes a magnetic sensor and a magnet for detection.

Engineering Contradiction Analysis
1Manufacturing precision
If mechanical adjustment methods are used for head module positioning, then the structure remains simple, but the angular deviation adjustment precision is insufficient leading to image defects
Solution Approach 1:
The patent replaces traditional mechanical adjustment methods with a rotation support mechanism that enables precise angular deviation adjustment. This mechanism allows the head module to be rotated about a rotation axis, substituting coarse mechanical positioning with a more refined rotation-based adjustment system that achieves higher precision without proportionally increasing overall system complexity
Solution Approach 2:
The patent changes the adjustment parameter from linear positional adjustment to angular rotational adjustment. By introducing a rotation axis and enabling angular deviation adjustment as a separate parameter, the system can independently control the orientation of the head module without affecting its positional parameters, thereby achieving higher precision in angular alignment
2Manufacturing precision
If high-precision assembly is performed to suppress rotation direction error, then adjustment function is eliminated, but small angular deviations still cause image defects
Solution Approach 1:
The patent implements preliminary angular deviation adjustment through the rotation support mechanism before final assembly and imaging. By allowing adjustment of the rotation direction during the assembly process, the system can pre-correct angular deviations that would otherwise cause image defects, ensuring reliability without requiring excessively high assembly precision
Solution Approach 2:
The patent introduces a feedback mechanism where the angular deviation is detected and measured, then used to guide further adjustment of the rotation support mechanism. This closed-loop feedback system ensures that angular deviations are accurately corrected to prevent image defects, maintaining image quality reliability through iterative refinement
