摘要： An actuator for an optical pick-up and a method of rolling a driving coil using the same. The actuator for the optical pick-up includes a bobbin for holding an object lens, a suspension for connecting the bobbin to a holder, and a magnetic driver. The magnetic driver includes a pair of permanent magnets respectively positioned near opposite sides of the bobbin, a plurality of tracking coils with pairs of the tracking coils rolled on opposite side surfaces of the bobbin, and a focus coil rolled around the bobbin and the plurality of tracking coils. The plurality of tracking coils and focus coil receive current to move the optical pickup through interaction with the permanent magnets, and a strong force is generated by narrowing a distance between the permanent magnets and the focus coil based upon the focus coil being rolled around the bobbin and the tracking coils. Accordingly, it is possible to improve the sensitivity and to prevent improper tilting of the actuator.

摘要： An optical pickup assembly having an elastically supported tilt mechanism. The optical pickup assembly includes a bobbin at which an objective lens is mounted and an elastic support member which supports the bobbin in elastic motion with respect to a holder installed at a base. A focus coil and a tracking coil are installed at the bobbin and form a conducting path for driving the objective lens in a focusing direction and a tracking direction. Tilt coils are installed at one side of the bobbin and form a conductive path for driving tilt of the objective lens. A first magnet and a first yoke generate an electromagnetic force to driving the objective lens together with the current carrying focus coil and tracking coil. A second magnet and a second yoke generate an electromagnetic force to driving the objective lens together with the current carrying tilt coils. A position detecting sensor measures relative inclination of the objective lens with respect to a disk, and a balance member coupled to the bobbin to balance the weight of the tilt coils by applying weight corresponding to the weight of the tilt coils at positions symmetrically opposite to the positions of the tilt coils.

摘要： A pickup actuator capable of significantly reducing rolling of the area, including: a pickup base, a lens holder having an objective lens mounted thereon, and lens holder driving means for driving the lens holder in directions for focusing and tracking on the pickup base. The lens holder driving means includes at least one magnet, a yoke for concentrating the magnetic flux of the magnet in the direction of the magnetic flux, and a driving coil having a focusing coil and a pair of tracking coils positioned between the magnet and the yoke. The respective widths of the magnet and the yoke are set at a rate of 1:0.8-1.2. Accordingly, the uniform magnetic flux area of the magnetic flux can be widely distributed in the width's direction of the yoke. Further, the magnet is attached to one side of one yoke while being slightly lowered thereon, so that the center of the magnetic flux of the magnet is downwardly moved from its initial position to a distance corresponding to 4-12% of the height of the magnet, and the center line of the magnetic flux of the magnet and the center line of the focusing coil are aligned with each other, exactly. Further, the width of the magnet and the gap between the pair of tracking coils are set at a rate of 1:0.6-0.9. Accordingly, the portions of the pair of tracking coils intersecting the effective magnetic flux area are positioned in the area where the density of the magnetic flux is low, so that the force in the focusing direction by the tracking coils can be reduced.
