Abstract
In the present application, a disc storage apparatus is disclosed. The disc drive is of the type that has a transducer head assembly connected to a pivoting assembly at one end thereof. The other end of the pivoting assembly is pivotally movable about a pivot axis. A voice coil motor is used to actuate the pivoting assembly to move the transducer heads over the surface of the data discs. The pivoting assembly further has a support member connecting the transducer assembly to the pivot axis. The support member has an arcuate region substantially at the location of the voice coil motor which is near the center of percussion. The arcuate region is arched in a direction to the plurality of discs and provides greater mechanical stability, thereby resulting in greater frequency response.
