Patent ID: 8406099

Claim:
An optical disc apparatus comprising: a focus-drive voltage output unit configured to output a focus drive voltage for moving an objective lens in a thickness direction of an optical disc; a focus-drive voltage acquisition unit configured to acquire at least one average value of focus drive voltages while the optical disc is rotating at least one time in an in-focus condition in which a laser beam emitted via the objective lens is in focus to a data layer of the optical disc and to record the average value in a recording unit; a voltage setting unit configured to set a closest-position voltage based on the average value, the closest-position voltage being a focus drive voltage at which the objective lens is moved closest to the optical disc in a focus search that is performed after the average value has been recorded in the recording unit; and a focus-search control unit configured to perform the focus search by moving the objective lens between a specific starting position and a position corresponding to the closest-position voltage.
