Abstract
An apparatus for managing defects and recording and/or reproducing real time data for a recording medium. The recording and/or reproducing apparatus stores information representing use or non-use of linear replacement defect management in which a defective area on the recording medium is replaced with the spare area, in order to record real time data on the recording medium. While maintaining compatibility between the defect managing method and a defect managing method based on a current DVD-RAM standard, i.e., while allowing a report of the fact that there are blocks which have not been linearly replaced, linear replacement is not performed when real time data is recorded. Thus, real time data can be recorded and reproduced.
Claims10
Apparatus for managing defects and recording and/or reproducing information on and/or from a recording medium, comprising a pickup unit and a controller to control the pickup unit to record and/or reproduce, on the recording medium, defect management mode information, of at least a flag, to show a plurality of defect management modes representing replacement or non-replacement of a defective unit which occurs after initialization of the recording medium.
An apparatus for managing defects for, and recording and/or reproducing to/from, a recording medium, comprising:
- a pick-up unit to record and/or reproduce information, representing replacement or non-replacement of a defective unit which occurs after initialization of the recording medium;
- and
- a control unit to determine whether a defective unit of the recording medium is to be replaced by a block in a spare area, according to the information representing replacement or non-replacement of a defective unit.
A defect managing method for an optical storage medium and recording and/or reproducing apparatus, comprising:
- recording information representing replacement or non-replacement of a defective unit which occurs after initialization of the optical storage medium;
- and
- determining whether the defective unit will be replaced by a block in a spare area of the storage medium according to the information representing replacement or non-replacement.
An apparatus for managing defects of a recording and/or reproducing storage medium, comprising:
- a pick-up unit to record and/or reproduce defect management information representing whether replacement or non-replacement by a linear replacement operation of a defective unit of the storage medium is required;
- and
- a control unit to replace the defective unit by a block in a spare area of the storage medium if the recorded defect management information indicates that a defective unit requires replacement by linear replacement, and not replacing the defective unit even if the defective unit was previously designated for linear replacement if the defect management information indicates that the defective unit is not to be replaced by linear replacement.
