1. A computer readable medium having a data structure for managing a data area of the computer readable medium, the data area having a user area and a non-user area, the user area including a plurality of recording-units, the computer readable medium comprising:
- a first management area storing a first data block including a plurality of sectors and a second data block including a plurality of sectors, the first management area being a temporary defect management area, the first data block having first information including recordation status indicating whether or not each recording unit of the user area has recorded data and the second data block having second information including a defect list, wherein respective last sectors of the first and second data blocks include third information including a first pointer pointing to an address where latest first information is recorded and a second pointer pointing to an address where latest second information is recorded; and
a second management area storing a latest first data block recorded in the first management area when no further recording of user data is made on the computer readable medium, the second management area being a defect management area.
