Abstract
An actuator assembly in a disk drive includes an actuator arm having a first distal end supporting a transducer head and a second distal end opposite to said first distal end supporting a movable voice coil section of a voice coil motor. The voice coil section comprises a coil, inner and outer bobbins positioned respectively at inner and outer sides of the coil, and a plurality of coil guides installed at respective corners of the inner bobbin for fixedly guiding the coil so as to prevent distortion due to difference in thermal expansion coefficients between the plastic bobbins and the coil during insertion molding in order to enhance a combining force between the coil and the bobbins. A gap of at least 0.5 mm is formed between the coil guides and the coil for separating the coil from the coil guides to prevent damages due to friction therefrom. The inner bobbin further comprises a plurality of guide holes perforated at corners for mounting the coil guides.
