Patent ID: 7675824

Claim:
An optical disc apparatus comprising: an optical pickup for outputting a signal on the basis of reflection light of the optical disc, the optical pickup including an objective lens; a driving section for moving the objective lens of the optical pickup relatively to an optical disc surface; and a focus controlling section for carrying out a focus detecting operation by detecting a reflection signal on a signal surface of the optical disc from the output signal of the optical pickup within a predetermined range of distance between the objective lens and the optical disc surface while the objective lens is being moved relative to the optical disc surface by means of the driving section, wherein the driving section staffs to move the objective lens relative to the optical disc surface from a predetermined initial point at a substantially fixed speed, the focus controlling section restricts the detection of the reflection signal on the signal surface of the optical disc until a predetermined time period has passed from a predetermined reference point of time after the start of the relative movement, and detects the reflection signal on the signal surface of the optical disc after the predetermined time period has passed to perform the focus detecting operation within the predetermined range of distance, and the predetermined time period is determined based on a time period between a time when the signal due to the surface reflection on the surface of the optical disc is detected and a time when a fake signal due to the surface reflection on the surface of the optical disc is detected.
