Abstract:
1. An information processor comprising: an optical disc drive comprising a loading mechanism configured to load an optical disc and to eject the optical disc; a recorder configured to obtain state information indicating an operating state of the loading mechanism, and to store a log of the state information; and a determination module configured to determine that there is a risk of failure in the loading mechanism when a rate of increase from a previous value to a most recent value is greater than a predetermined threshold value, the previous value being before the most recent value, the most recent value and the previous value corresponding to the determination of the risk of failure of the loading mechanism, the most recent value being calculated by combining a plurality of indices comprised in the state information recorded most recently, the previous value being calculated by combining a plurality of indices comprised in the state information recorded previously before the most recent recording of the state information.
