Abstract
A low profile, high capacity, high performance disk drive includes a plurality of disk surfaces mounted in parallel for simultaneous rotation about an axis. Each of a plurality of data transducer heads for reading and/or writing data to the data surfaces is attached to a slider. A stacked arm actuator for moving the data transducer heads in a radial direction across the disk surfaces includes a supporting arm and a suspension load beam attached to the supporting arm. The suspension load beam connects the supporting arm to the slider. The suspension load beam includes a load dimple bearing on the slider and has opposed stiffening flanges extending in a plane adjacent the slider. The actuator includes a stack of 9 head arm suspension assemblies and the stack has a height of 16.634 mm. An interdisk spacing of less than 1.4 mm provides a height dimension of 14.635 for a stack of 8 disks. Shock and electrical isolation is accomplished using four mounting blocks carrying energy absorbing, highly damped, resilient material.
