Abstract

An apparatus for reproducing a recording medium having a recorded defect management area. The apparatus includes a pickup reading data from a recording medium and a controller controlling the pickup to read data on the recording medium and determining whether the recording medium contains predetermined data, recorded in response to a finalization command, to prevent recording with respect to the recording medium. The controller determines whether an area of a temporary defect management area not having defect management data includes the predetermined data by checking whether the temporary defect management data is filled with repetitions of a predetermined value.
