Abstract:
An optical disc drive apparatus which is mounted on a mobile apparatus, which at least reads information from a disc surface of an optical disc disposed in a predetermined position by using a pickup, which is robust against vibration, and which is capable of preventing collision between the disc surface of the optical disc and the pickup. The apparatus judges a road surface condition associated with location information on the basis of the location information concerning a location on a road on which the mobile apparatus is traveling, acquired externally and road surface condition information depending upon a road surface condition of a road on which the mobile apparatus travels. Servo characteristics of the optical drive apparatus are controlled according to control information associated with the judged road surface condition.
