摘要： In a variable shape mirror including a base substrate; a mirror with a mirror surface; a fixed part, arranged on the base substrate, for fixing the mirror and the base substrate; and an actuator using a piezoelectric ceramics arranged between the base substrate and the mirror; an initial voltage of the actuator is a negative voltage. The initial voltage differs for each actuator; and is larger than or equal to a voltage at which a displacement of the actuator becomes minimum and smaller than zero voltage. The negative initial voltage is a bias voltage, and a voltage stroke is performed while applying the bias voltage.

摘要： A variable shape mirror includes a support substrate, a mirror substrate that is opposed to the support substrate, a fixing member that is disposed on the support substrate and fixes the mirror substrate, and a piezoelectric element that is disposed on the support substrate and is expanded or contracted so that a reflection plane of the mirror substrate can be deformed. A coefficient of linear expansion of the fixing member is larger than a coefficient of linear expansion of the piezoelectric element. A back surface of the mirror substrate is provided with a metal bonding layer that is disposed in at least a portion to be bonded to the fixing member. The metal bonding layer enables the mirror substrate and the fixing member to be bonded to each other by pressing the mirror substrate and the fixing member to each other while they are heated. The mirror substrate and the piezoelectric element are not bonded to each other.

摘要： An optical pickup device has a variable-shape mirror that reflects a light beam emitted from a light source and that, by use of piezoelectric elements sandwiched between a support substrate and a mirror portion arranged to face the support substrate, corrects for wavefront aberrations in the light beam by deforming a mirror surface of the mirror portion, and converging means for directing, while condensing, the light beam reflected from the variable-shape mirror to a recording surface of an optical recording medium. Let a direction perpendicular to the travel direction of the light beam emitted from the light source be the X direction on the mirror surface and let the direction perpendicular to the X direction be the Y direction on the mirror surface, the mirror surface is inclined about the X direction such that the mirror surface forms a predetermined angle relative to the travel direction of the light bean emitted from the light source. The piezoelectric elements are arranged symmetrically about the center axis of the mirror surface, with two of them arranged in the X direction and another two in the Y direction. The piezoelectric elements are arranged on the support substrate such that, when all of them are driven with equal voltages, the curvature of the mirror surface in the X direction relative to the curvature of the mirror surface in the Y direction fulfills a predetermined curvature ratio.
