Abstract
A method and system for minimizing loss of critical digital data while such data is being written to a storage medium. The critical digital data is written to a digital storage medium in small blocks or segments. As each segment is transferred to the storage medium, the file allocation table is updated and the file is closed. By segmenting the files into smaller file segments, the amount of critical data lost as a result of a system failure or power loss is reduced. During playback, the file segments are dynamically assembled allowing playback of the digital data in a continuous manner.
Claims24
A data recording system which minimizes the risk of loss of data resulting from a loss of power, the recording system comprising:
- a recording subsystem for recording data, the recording subsystem including a system for recording a predetermined block of data into a plurality of segmented files and closing the segmented files after each of said segmented files has been loaded.
A data playback system for playing back segmented data files, the data playback subsystem comprising:
- a system for assembling segmented video files based upon a file list of file segments within a file.
