Abstract
There is provided 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 includes 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. The lens guide portion has an adhesive confining groove in which adhesive can be injected to securely fix the object lens.
