Claim:
A method for managing a defective area on a recording medium, comprising the steps of: (a) receiving a command for data writing with data to be written, the command including LBA (Logical Block Address) for designating a position to be written, a transfer length for indicating an amount of data to be written, and a write type information for identifying whether or not there is real time or non-real time writing; (b) controlling a write operation based on the command such that a linear replacement for a defective area of the recording medium is not performed when the write type information identifies real time writing, while a linear replacement to a spare area is performed when the write type information identifies non-real time writing; and (c) generating a defect entry on the defective area, the defect entry including a location of the defective area and a status information for indicating non-replaced defective area regarding the linear replacement to the spare area when the write type information identifies the real time writing.
