12. The method of claim 9, wherein the event occurs if a recordable recording area in the user area is changed to a non-recordable recording area during the sequential recording mode.

13. An apparatus for reproducing data from a recording medium, comprising:

a pick up configured to read data from the recording medium; and

a controller, operatively coupled to the pick up, configured to control the pick up to read a data block from a temporary management area of the recording medium, the data block including use status information indicating use status of a user area of the recording medium, wherein the use status information is updated when an event occurs, and the use status information is determined to be one of sequential recording information and a space bit map according to a recording mode, the sequential recording information providing information on recording areas allocated in the user area of the recording medium if the recording mode is a sequential recording mode and the space bit map providing information on a recording status of each recording unit of the user area if the recording mode is a random recording mode, wherein

after one of the recording modes is selected, the selected recording mode is used until the recording medium is to be finalized, and after the recording medium is finalized the recording medium is not used to record data thereon.
