Claims

[Claims for Utility Model Registration] (1) A performance means including an optical pickup that has an objective lens and emits light onto the recording surface of a rotating optical information recording disk and reads information by the reflected light; reproduction processing means for generating a reproduction signal by reproducing the information signal obtained from the means;
an optical disk player comprising tilt servo means for adjusting the optical axis of the optical pickup, wherein the tilt servo means is provided to be swingable in a plane including the disk rotation axis and includes a support that supports at least the objective lens; a member, an inclination angle detection means for detecting a relative inclination angle between the optical axis of the irradiated light and the recording surface and emitting an inclination angle detection signal; and detecting the presence of a reproduction signal from the reproduction processing means and generating a reproduction signal. reproduction signal presence detection means for emitting a presence detection signal; and drive means for positioning the support member to either a neutral position or at least one tilt adjustment position according to the tilt angle detection signal and the reproduction signal presence detection signal. An optical disc player comprising: (2) The optical disc player according to claim 1, wherein the driving means is an electromagnetic plunger.
