Abstract
A method of and drive for recording medium defect management, and a defect managed recording medium. The defect management method includes: writing first state information that specifies that an update cycle of a temporary defect management structure (TDMS) is open when updating of the TDMS begins, the TDMS containing information regarding temporary defect management; updating the TDMS when data is written to or read from the information storage medium; and writing second state information that specifies that the update cycle of the TDMS is closed, when the updating of the TDMS is completed.
Claims16
A method for reproducing data recorded on an information storage medium comprising:
- reading first state information from the information storage medium that specifies that an update cycle of a temporary defect management structure (TDMS) of the information storage medium is open, the TDMS containing information regarding temporary defect management;
- and
- reading second state information from the information storage medium that specifies that the update cycle of the TDMS is closed, when updating of the TDMS is completed.
A method for reproducing data recorded on an information storage medium, the method comprising:
- reading first state information, which specifies that an update cycle of information for defect management is open, from an area of the information storage medium;
- and
- reading second state information, which specifies that the update cycle of the information is closed, from the area when updating of the information is completed, wherein the information is updated to manage defect when data is read from the information storage medium.
A method for reproducing data recorded on an information storage medium by determining whether defect management of an information storage medium was abnormally terminated due to an abnormal event, the method comprising:
- reading state information that specifies whether an update cycle of a temporary defect management structure (TDMS) of the information storage medium is open or closed, the TDMS containing information regarding temporary defect management;
- and
- determining that the TDMS is up-to-date where the update cycle of the TDMS is closed and that the TDMS is not up-to-date where the update cycle of the TDMS is open.
