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.
Claims18
An apparatus for reproducing data recorded on an information storage medium, the apparatus comprising:
- a pickup that reads data from the information storage medium;
- and
- a controller that controls the pickup to read first state information, which specifies that an update cycle of a temporary defect management structure (TDMS) of the information storage medium is open, from an area of the information storage medium, the TDMS containing information regarding temporary defect management, and
- controls the pickup to read second state information, which specifies that the TDMS update cycle is closed, from the area when updating of the TDMS is completed.
An apparatus for reproducing data recorded on an information storage medium, the apparatus comprising:
- a pickup that reads data from an information storage medium;
- and
- a controller that controls the pickup to read first state information, which specifies that an update cycle of information for defect management is open, in an area of the information storage medium, and controls the pickup to read second state information, which specifies that the update cycle of the information is closed, in the area when updating of the information is completed, wherein the information is updated to manage a defect when data read from the information storage medium.
An apparatus for reproducing data recorded on an information storage medium, the apparatus comprising:
- a pickup that reads data from a loaded information storage medium;
- and
- a controller that controls the pickup to read 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, wherein the drive determines 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.
An apparatus for reproducing data recorded on an information storage medium, the apparatus comprising:
- a pickup that reads data from an information storage medium;
- and
- a controller that controls the pickup to read state information that specifies whether an update cycle of information for defect management is open or closed, from an area of the information storage medium, wherein:
- the drive determines that the information is up-to-date where the update cycle is closed and that the information is not up-to-date where the update cycle is open, and
- the information is updated to manage a defect when data is read from the information storage medium.
A defect management method for an information storage medium in which a temporary defect management information (TDDS) including information on update state of a temporary defect management structure (TDMS) is recorded, comprising:
- when updating of the TDMS is completed, writing the TDDS including information that specifies that update state of the TDMS is “closed”, to the information storage medium.
