Abstract
A hard disk drive architecture includes a housing including a continuous base wall and continuous sidewalls extending from the base wall, and cooperating with a cover structure for enclosing and sealing an interior space for a plurality of rigid data storage disks mounted on a spindle, and a rotary actuator structure for positioning a stack of data transducer heads relative to concentric track locations defined on storage surfaces of the disks. The spindle includes a spindle motor for rotating the spindle and the disks. The housing defines an exterior recess region of the base wall. The recess region includes an opening for a connector pin array. A seal is provided for sealing the opening after the connector pin array is in place. A flex circuit mounting bracket within the interior space is provided for positioning and connecting to a flex circuit connecting to the rotary actuator structure and to the connector pin array. An analog read/write channel printed circuit board is located within the exterior recess region and includes an analog circuit connector socket for connecting to the connector pin array. A digital electronics main printed circuit board overlies the exterior recess region, connector pin array and analog read/write channel printed circuit board and includes a digital circuit connector socket for connecting to the connector pin array.
