Abstract
An enclosure for a rigid disk data file is shown which includes a base casting and a cover that interface along planar surface that is not perpendicular to the axis of the spindle supporting the data disks. The base casting at one side extends axially along the disk stack and has the transducer positioning actuators mounted through openings therein. At the opposite side, the disk stack is fully exposed to permit easy access to the disk surface for procedures such as servo writing during manufacture of the drive. This structure makes possible concurrent operation of the product heads and servo writing heads.
