Abstract
A method for real time recording and playback of data to and from an optical recording medium, and a method for managing a file thereof is disclosed. In the present invention, the host controls real time data writing by providing a signal requesting for information on a defective area to the device for recording/playback of data to/from an optical disk before providing a write command. Accordingly, the write command is generated such that data is not written on the defective areas, based upon the returned information on the defective area. Alternatively, the host may first provide a write command to the device for recording/playback of data to/from an optical disk, upon which information on defective areas is returned. Thus, the host generates and provides a new write command such that data is not written on a defective area based upon the returned information on the defective area.
