Abstract:
1. An information processor comprising: an optical disc drive; an identification information receiver configured to receive identification information associated with an optical disc in the optical disc drive based on information from the optical disc; a storage module configured to store information related to failure analysis of the optical disc in state information indicating a reading state upon reading from the optical disc or a writing state upon writing to the optical disc in association with the identification information; and a determination module configured to calculate failure indicator values indicating levels of failure of the optical disc based on logs of the information related to failure analysis of the optical disc in association with the identification information and to determine whether the failure indicator values satisfy a predetermined condition to determine whether there is a risk of disc error, wherein the information related to failure analysis of the optical disc includes double-speed down information indicating that double speed reading or writing is slowed down.
