Recording Apparatus Multi-Media Synchronization Control

Solution Overview
Problem
Existing recording apparatuses face challenges in ensuring that moving image files with the same contents recorded on multiple media have identical contents, especially when one recording medium runs out of space during simultaneous recording, leading to potential differences in content across media.
Innovation Solution
A recording apparatus with an input unit, generating unit for identification information, and a control unit that manages the recording process by adding the same identification information to moving image files across multiple media, and if one medium's capacity is low, it stops recording on that medium and starts a new file on others with different identification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If recording continues on a medium that has run out of space during simultaneous recording, then the recording space capacity is fully utilized, but the content consistency across multiple recording mediums is compromised
Solution Approach 1:
The control unit detects the recording space capacity of each recording medium in advance before running out of space and performs preliminary action by stopping the recording to that medium before the capacity is completely exhausted. This prevents the harmful effect of content inconsistency while maximizing the utilization of recording space capacity.
2Ease of operation
If the same identification information is added to moving image files recorded on multiple mediums, then file identification is simplified, but content differences may exist undetected when one medium runs out of space
Solution Approach 1:
The control unit monitors the recording space capacity of each recording medium in real-time during simultaneous recording and provides feedback to make dynamic control decisions. When the capacity of one medium is insufficient, the system stops recording to that medium while continuing to others, ensuring content consistency across all mediums.
3Reliability
If recording is stopped to one medium during simultaneous recording, then content consistency is maintained, but the recording space capacity is not fully utilized
Solution Approach 1:
The control unit detects the recording space capacity of each recording medium in advance before running out of space and performs preliminary action by stopping the recording to that medium before the capacity is completely exhausted. This prevents the harmful effect of content inconsistency while maximizing the utilization of recording space capacity.

AI summary
In a recording mode for simultaneously recording moving image files onto a plurality of recording mediums, a recording apparatus adds same identification information to the respective moving image files to be simultaneously recorded onto the plurality of recording mediums and record the obtained files in such a manner that when a recording space capacity of one of the plurality of recording mediums is smaller than a predetermined value or when there is an instruction to stop the recording to a designated recording medium among the plurality of recording mediums, the respective moving image files which are being recorded onto the plurality of recording are closed.
