A drive apparatus of the present invention includes a recording/reproduction section and a drive control section. The drive control section at least performs a process including: allocating a contiguous area to a specific location in the user data area other than the location specified by the recording instruction; controlling the recording/reproduction section to record the data in the allocated contiguous area; and generating new disc management information including first replacement management information for mapping a start location of the contiguous area specified by the recording instruction to a start location of the allocated contiguous area and second replacement management information for mapping an end location of the contiguous area specified by the recording instruction to an end location of the allocated contiguous area.
