Information Processing Apparatus Position Data Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses that record content and position information independently often waste storage capacity because position information cannot be deleted when content is deleted, leading to inefficient use of recording media.
Innovation Solution
An information processing apparatus with a deletion unit that automatically removes position information associated with deleted content from the recording medium, either by date or entirely, to conserve storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position information is recorded independently of content, then position information can be preserved for historical records, but storage capacity is wasted when content is deleted
Solution Approach 1:
The patent merges the management of content and position information by establishing temporal association between them. When content is deleted, the system automatically identifies and deletes associated position information, preventing storage waste while maintaining reliability for preserved content.
Solution Approach 2:
The system dynamically manages position information based on content status. Position information transitions from being permanently retained to being automatically deleted when its associated content is removed, making the storage management adaptive rather than static.
2Ease of operation
If position information is not associated with content, then position information can be retained independently, but automatic deletion of position information when content is deleted cannot be achieved
Solution Approach 1:
The system implements feedback mechanisms where deletion of content triggers automatic identification and deletion of associated position information. This feedback loop enables automatic deletion efficiency while maintaining the operational simplicity of independent management through temporal association markers.
Solution Approach 2:
The system performs preliminary association between content and position information during the recording phase by tagging position data with temporal identifiers. This preliminary action enables subsequent automatic deletion operations without requiring complex real-time analysis.
3Quantity of substance
If all position information is deleted when any content is deleted, then storage capacity is maximized, but position information for remaining content may be incorrectly deleted
Solution Approach 1:
The patent applies local quality by making position information deletion selective rather than universal. Each position information record is individually evaluated based on its temporal association with specific content, ensuring only the locally relevant position data is deleted when its associated content is removed.
Solution Approach 2:
The system segments position information into distinct temporal associations with individual content items. This segmentation allows the deletion operation to target only the specific position information linked to deleted content, preserving position data for other content items that remain in storage.
Data Source
AI summary
An information processing apparatus is provided, in which content and position information generated independently of each other are recorded in a recording medium. The apparatus includes a recording medium in which the content and the position information are recorded and a deletion unit deleting position information temporally associated with a piece of the content from the recording medium when the piece of content is deleted from the recording medium.
