PROBLEM TO BE SOLVED: To provide an optical disk apparatus, a gap servo device and a gap pull-in control method.SOLUTION: An optical disk apparatus 1 of the present invention includes: a stabilization plate 21 for stabilizing rotation of a thin optical disk 2; a spindle motor 4 for rotatably driving the thin optical disk 2; an SIL optical head 6 for fixing an objective lens 5; tilt actuators 18, 19 for adjusting the tilt amount of the SIL optical head 6 with respect to the thin optical disk 2; a gap actuator 7 for controlling a gap between the SIL optical head 6 and the thin optical disk 2; and a control part 14 for controlling the tilt actuators 18, 19 and the gap actuator 7. The control part 14 functioning as a gap servo device performs control so as to adjust, at the time of an initial setting, the tilt amount of the SIL optical head 6 with respect to the stabilization plate 21, and to perform, at the time of recording and reproduction, gap pull-in for the thin optical disk 2 on the basis of the adjusted tilt amount. |
