Method of and apparatus for managing disc defects using temporary defect management information (tdfl) and temporary defect management information (tdds), and disc having the tdfl and tdds

An apparatus for use with a write-once disc having a user data area in which user data is recorded, a temporary defect management area, a defect management area other than the temporary defect management area, and a spare area other than the user data area and which comprises a substitute area for a defective area existing in the user data area, the apparatus comprising:

• a reading unit that reads data from the disc, the disc being the write-once disc;
• and
• a controller that controls the reading unit to transfer user data with respect to the user data area, and read temporary defect information and temporary defect management information in the temporary defect management area of the disc,
• wherein:
• the temporary defect information and the temporary defect management information are recorded for a recording operation for use by the recording and/or reproducing apparatus to perform disc defect management,
• the temporary defect management information comprises information on a recording position of the temporary defect information,
• the temporary defect information comprises a defect position pointer that points to a position of a defective area in the user data area and a replacement position pointer that points to a position of the replacement data that replaces a portion of the user data recorded in the defective area, and
• the defect management area is reserved for the apparatus to record copies of last recorded temporary defect information and last recorded temporary defect management information for use by the recording and/or reproducing apparatus to perform disc defect management after finalization of the disc.

A recording apparatus for use with a disc having a user data area, a temporary defect management area, and a spare area other than the user data area, the apparatus comprising:

• a recording unit that records data on the disc;
• and
• a controller that controls the recording/reading unit to
• record user data in the user data area of the disc,
• again record user data that was recorded in a defective area of the user data area in the spare area so as to make replacement data for the user data recorded in the defective area, and
• record an address of last data, which is last recorded in the user data area, in the temporary defect management area, the temporary defect management area being an area that is used by the apparatus to perform disc defect management with respect to the disc.

A recording apparatus for use with a storage medium having a user data area, a temporary defect management area, and a spare area other than the user data area, the apparatus comprising:

• a pickup unit that records user data to the user data area, the user data area comprising a first defective area;
• and
• a controller that determines an available portion of the user data area and the spare area using a first address and a second address and controls the pickup unit to
• record the user data to the user data area,
• record first replacement data to the spare area, the first replacement data comprising a portion of the user data that was recorded in the first defective area, and
• record first management information to the management area, the first management information being used by the controller to manage the user data and the first replacement data and comprising the first address comprising an address of the first replacement data or a next address of the spare area for a next defective area replacement, and the second address comprising an address of a last portion of the user data to be recorded in the user data area prior to creation of the first defect information.

A method of reproducing data from a disc comprising:

• a user data area in which user data is recorded;
• a spare area other than the user data area and which comprises a substitute area for a defective area existing in the user data area;
• and a temporary defect management area which comprises temporary defect information and temporary defect management information recorded for a recording operation to perform disc defect management, the method comprising:
• detecting from the temporary defect management area the temporary defect information and the temporary defect management information;
• and
• reproducing data from the user data area using replacement data recorded in the spare area as determined according to the detected temporary defect information, the temporary defect management information, and/or address of last data,
• wherein the temporary defect management area includes location information of last data that is last recorded in the user data area.

A method of reproducing data from a storage medium, comprising:

• reproducing user data from a user data area of the storage medium, the user data area comprising a first defective area;
• detecting, from a management area of the storage medium other than the user data area, a first temporary defect information area corresponding to the first defective area and comprising first temporary defect information regarding the first defective area and a copy of the first temporary defect information that consists of the first temporary defect information;
• and
• using the detected first temporary defect information and/or the copy of the first temporary defect information to perform defect management to reproduce first replacement data indicated as corresponding to the first defective area.
