A recording and/or reproducing method, a recording and/or reproducing apparatus, and a computer readable recording medium storing a program for performing the method. A recording unit block in which invalid data is partially padded is written on an information storage medium along with padding information indicating that the invalid data is included in the recording unit block. The padding information is useful in determining whether the recording unit block includes the padding data. Accordingly, unnecessary retrial processes of a drive system are reduced such that the performance of the drive system is improved and error correction capability is enhanced.

Recording and/or reproducing method, recording and/or reproducing apparatus, and computer readable recording medium storing program for performing the method

A recording method for use by an apparatus and/or which is encoded on a computer readable medium includes selecting a defect management on mode or a defect management off mode that indicates whether defect management is to be performed or not while data is recorded in the recording medium, recording the data in the recording medium while defect management is performed on the recording medium, if the defect management on mode is selected, and recording the data in the recording medium without defect management, if the defect management off mode is selected.

Recording/reproducing method, recording/reproducing apparatus, optical recording medium, and computer readable recording medium having recorded thereon program for the recording/reproducing method

A recording medium on which a recording/reproducing unit block is recorded, an apparatus to record and/or reproduce data on/from the recording medium, and a method of recording/reproducing the data on/from the recording medium. The recording/reproducing unit block comprises invalid data used in disc certification, and an identifier to indicate that the invalid data is included in the recording/reproducing unit block, the invalid data being used during the disc certification on a portion of the recording medium or the entire recording medium.
