Recording Apparatus Identification Information Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses for moving images and audio signals on multiple media require users to manually verify and match recording settings across different media, leading to cumbersome operations and potential errors when different settings are used.
Innovation Solution
A recording apparatus and method that allows independent setting of conditions for multiple recording media, generating unique identification information for each set of data to ensure easy identification of matching or differing settings across media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identical moving images are simultaneously recorded on multiple recording media, then reliability is improved, but operation complexity increases due to troublesome reproduction and search operations
Solution Approach 1:
The patent segments the identification of recorded data by assigning unique identification information to each recording medium. This allows the user to identify and select specific recorded data from different media without having to reproduce and search through all of them, thus reducing operation complexity while maintaining reliability.
Solution Approach 2:
The patent introduces identification information as an intermediary element between the recorded moving images and the user. This identification information serves as a mediator that enables the user to easily identify and access recorded data on different media without directly interacting with the reproduced images, thereby simplifying operations.
2Adaptability or versatility
If different recording conditions are set for multiple recording media, then adaptability is improved, but identification difficulty increases when verifying matching settings
Solution Approach 1:
The patent performs preliminary action by generating and assigning identification information to each recorded data set based on the recording conditions before the user needs to verify them. This pre-assignment of identification information based on recording conditions (such as data rate, number of pixels, and recording medium type) allows the user to easily identify matching settings without having to manually verify each parameter.
Solution Approach 2:
The patent implements feedback by providing identification information that reflects the recording conditions to the user. This feedback mechanism allows the user to understand the settings used for each recording medium and verify matching conditions easily, thus reducing identification difficulty while maintaining adaptability.
3Measurement precision
If identification information is generated based on recording conditions, then identification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent uses copying by creating identification information that replicates the essential characteristics of the recording conditions (such as data rate, number of pixels, and recording medium type) in a simplified form. This copied identification information provides accurate identification without requiring the system to store or process all the original detailed settings, thus reducing device complexity while maintaining identification accuracy.

AI summary
A recording apparatus independently sets conditions of information data to be simultaneously recorded in a plurality of recording media in a simultaneous recording mode according to a user instruction. The recording apparatus processes information data according to the set conditions so as to generate a plurality of information data to be recorded in the plurality of recording media in the simultaneous recording mode, and their identification information, and records the plurality of generated information data and identification information in the plurality of recording media. When different conditions are set as the conditions of the information data to be simultaneously recorded in the plurality of recording media, a plurality of pieces of identification information which have different values are generated for the information data to be simultaneously recorded in the plurality of recording media.
