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.

Claims (14)

1. 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 on a disk drive, said data having a file size less than the maximum file storage capability of said disk drive, the recording subsystem including a system for breaking down said data into a plurality of segmented files that are relatively smaller than said file size of said data and storing said segmented files on said disk drive and closing each of said segmented files after each of said segmented files has been stored on said disk drive, wherein the size of said segmented files is user-selectable.

2. The data recording system as recited in claim 1 , further including a playback subsystem for assembling said segmented files defined by size and recording time for synchronous playback of said segmented files on a predetermined standard media player.

3. The system as recited in claim 1 , wherein the size corresponds to the length.

4. The system as recited in claim 1 , wherein the size corresponds to the recording time.

5. The system as recited in claim 1 , wherein said recording system is a multi-channel recording system.

6. The system as recited in claim 5 , wherein said recording system creates a top level directory, which identifies each of the channels.

7. The system as recited in claim 5 , wherein the number of channels is user defined.

8. The system as recited in claim 6 , wherein said recording subsystem wherein default file names are provided for each of said files in said top level directory.

9. The system as recited in claim 6 , wherein said recording subsystem enables the file names in said top level directory to be user specified.

10. The system as recited in claim 6 , wherein said recording system includes a first level subdirectory which session files, each time stamped and corresponding to a separate recording session.

11. The system as recited in claim 10 , wherein said files are named as pointers to actual file segments.

12. The system as recited in claim 10 , wherein said session files are named to include the recording session starting time.

13. The system as recited in claim 10 , further including a data capture filter for creating one or more segment files for each recording session file.

14. The system as recited in claim 13 , wherein the size of said segmentation files are user defined.
