摘要:
There is provided a compact optical disc apparatus having a small footprint actuator. 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.
