An optical pickup actuator for actuating a lens holder having an object lens according to an interaction between coils and magnets, the optical pickup actuator comprising;
- a lens-seating portion formed on the lens holder to support the object lens;
- and
- a lens guide portion protruding from the lens-seating portion to securely support the object lens, wherein the lens guide portion has an adhesive confining groove in which adhesive can be injected to securely fix the object lens.
An optical pickup actuator for actuating a lens holder having an object lens according to an interaction between coils and magnets, the optical pickup actuator, wherein the lens holder is provided at a side surface with a dissipation groove that does not directly contact a tracking coil.
An optical pickup actuator comprising:
- a lens holder having a lens-seating portion on which an object lens seats and a bobbin around which a focusing coil is wound, and a coil-supporting portion around which a tracking coil is wound,
- wherein the coil-supporting portion protrudes from a side surface of the lens holder and the side surface of the lens holder is provided with a coil-contacting portion contacting the tracking coil and a heat dissipation groove that does not contact the tracking coil.
