Abstract
A disk drive has an actuator coil that includes first and second lateral legs joined by first and second longitudinal legs to form a closed coil periphery. The first lateral leg is disposed closer to the actuator pivot bore than the second lateral leg. The first and second longitudinal legs join the second lateral leg at a first interior bend location and at a second interior bend location within the closed coil periphery, respectively. A bobbin is disposed within the closed coil periphery and contacts the conductive coil at two locations (e.g. the first interior bend location and the second interior bend location). Preferably, the bobbin defines a total bobbin length and an average bobbin width, and the total bobbin length is at least 3 times the average bobbin width.
