    摘要： An information recording and control method and apparatus for a recording medium disc having information previously recorded thereon. New information is overwritten at least a portion of the previously recorded information in a recording area of the recording medium disc. Information on the new information is cataloged as control information on the recording medium disc. Residual information which is part of the previously recorded information which is not overwritten by the new information is treated as new information and information on the residual information which is treated as new information is cataloged as control information on the recording medium disc.

    摘要： A realtime data recording method allows recovery of recorded file data upon occurrence of a fault, for use as a readable file. Prior to recording, initial management data are generated such that the entire area on a recording medium 1 is reflected as a recording range. After the initial management data has been recorded, data recording is started. During the recording, a writing status of the recording medium (or apparatus) is set as in-writing status, and realtime sector information generated in parallel to data recording is recorded in a non-volatile memory for management of a recording status. Upon restarting after a recording fault, the in-writing status of the recording medium 1 is read to see if the medium has been set open, and inconsistency between the recording information of the sector information and the in-writing status recording information is detected. Correct management data is recorded and re-recorded onto the recording medium.
