摘要： Disclosed is a compliant joint achieving passive compliance. The compliant joint includes a housing and a rotating member mutually rotatably provided; and a cam provided between the housing and the rotating member, and connected to the housing and the rotating member respectively. The cam is connected to the rotating member to rotate together with the rotation of the rotating member, or be independent of the rotating member so as to move in the axial direction of the rotating member separately from the rotating member. The cam is connected to the housing such that the cam can maintain the connection with the housing when external force below a designated value is applied to the rotating member, and release the connection with the housing in the case that external force more than the designated value is applied to the rotating member.

A tracking coil of a swing arm-type actuator is disposed substantially perpendicular to an arm and on the opposite side to an optical disc loading slot with respect to the line connecting the center of rotation of the optical disc to the center of swing movement of the actuator. A pair of permanent magnets are disposed such that they face the tracking coil and they are opposite in polarity. The tracking coil is disposed on both the permanent magnets such that the tracking coil straddles the boundary of the pair of permanent magnets.
