Method and apparatus for preventing overwriting of data by identifying unrecorded portions of a recording medium and recording information thereon

摘要

The present invention relates to a method and apparatus for recording and protecting information recorded on a recording medium. The method includes the steps of setting up a mode in which recording is performed on portions of the medium on which information has not been recorded in the medium, detecting portions of the medium where information has not been recorded in the recording medium, selecting a portion on which new information may be recorded among the detected portions, and recording new information from a starting position of the portion selected in the selecting step. According to the present invention, it is possible to prevent the unintentional erasure of the information recorded on the recording medium by confirming that the portion on which the information is recorded is a blank portion and recording new information on the blank portion.
