In a record operation mode, a nonvolatile memory stores a record end address. In a restoring operation mode, the record end address stored in the nonvolatile memory is read, and a record end address in an FDCB is read and is compared with the record end address read from the nonvolatile memory to determine whether these addresses match with each other or not. When the record end address in the FDCB is different from the record end address stored in the nonvolatile memory, the data in the FDCB is updated based on the record end address stored in the nonvolatile memory.
