Method for recovering management information of a recording medium and apparatus therefor

An apparatus for recovering disc management information of a recording medium, the recording medium including a user data area and a plurality of temporary disc management areas (TDMAs) on at least one recording layer, wherein each TDMA is for storing disc management information including a plurality of temporary disc management structures (TDMSs), each TDMS includes a temporary disc definition structure (TDDS), defect management information, and recording management information for enabling and controlling a recording mode on the recording medium, the apparatus comprising:

• a pickup head unit;
• a controller for controlling the pickup head unit to detect whether to recover disc management information if the recording medium is not closed;
• wherein the controller controls the pickup head unit to search the TDMAs for a readable TDMS which is a TDMS included in an in-use TDMA of the TDMAs and is readable, and determine whether a piece of information associated with an inconsistency flag of the readable TDMS is reliable or not;
• wherein when the controller detects that the piece of information associated with the inconsistency flag is unreliable, the controller determines at least a detection condition according to the information which is included in the readable TDMS and the in-use TDMA, and controls the pickup head unit to detect the recording medium to determine an update on the piece of information associated with the inconsistency flag, under at least a detection condition;
• wherein the controller generates an update TDMS according to the readable TDMS and the update on the piece of information associated with the inconsistency flag.
