Abstract
An apparatus of recording data on a recording medium includes an optical recording device and a microcomputer. The recording medium has a lead-in area, a lead-out area, and a data zone, where the data zone has a user data area and a spare area. When the microcomputer receives a command for physically overwriting first data in a first area within the user data area and determines that the first area is included in a pre-recorded area, it controls the recording device to record the first data in a first replacement area instead and to record a first entry in a TDMA, where the first entry specifies the locations of the first area and the first replacement area. In addition, when the microprocessor receives a command for recording second data in a second area within the user data area and finds the second area defective, it controls the optical recording device to record the second data in a second replacement area instead and to record a second entry in the TDMA, where the second entry specifies the locations of the second area and the second replacement area.
