Abstract:
1. An optical pickup actuator comprising: an objective lens which converges a light on an optical recording medium; a lens holder which holds the objective lens; a suspension wire which holds the lens holder; and projections which are provided at the lens holder; wherein the projections are provided at a periphery of the objective lens and at least one of the projections is provided on an upstream side of an insertion direction of the optical recording medium, each of the projections including at least two independent sloped surfaces that are sloped relative to the insertion direction of the optical recording medium and in different directions from each other, and wherein the at least two independent sloped surfaces are sloped in a direction away from the objective lens and configured such that when the optical recording medium contacts one of the at least two independent sloped surfaces at a time of inserting the optical recording medium, the optical recording medium is guided in a direction away from the lens holder and the lens holder is moved in a direction substantially perpendicular to the insertion direction.
