Disk drive system having open slot swage connection

A swage connection connecting a member to an actuator arm in a disk drive system, the swoon connection comprising:

• a first open slot located on a perimeter of said actuator arm, said first open slot passing through upper and lower surfaces of said actuator arm and extending into the actuator arm from a periphery thereof;
• a boss located on a proximal end of said member for registering with said open slot;
• said boss swaged within said first open slot with an outer surface of said boss expanded into an inner surface of said first open slot;
• a second open slot located on said perimeter of said actuator arm, said second open slot passing through said upper and lower surfaces of said actuator arm and extending into the actuator arm from said periphery thereof;
• a second boss located on said proximal end of said member for registering with said second open slot;
• said second boss swaged within said second open slot with an outer surface of said second boss expanded into an inner surface of said second open slot;
• and
• said first open slot and said second open slot being angled away from each other, wherein said member is fixedly attached to said actuator arm.

A disk drive system comprising:

• rotatably mounted, vertically spaced apart magnetic disks, a disk motor for rotating said rotatably mounted, vertically spaced apart magnetic disks, an actuator hub, actuator hub motor, a control circuit for controlling said disk motor and said actuator hub motor to allow selective positioning of read/write heads over said rotatably mounted, vertically spaced apart magnetic disks;
• an actuator arm extending radially from said actuator hub:
• a first open slot located on a perimeter of said actuator arm, said first open slot passing through upper and lower surfaces of said actuator arm and extending into the actuator arm from a periphery thereof;
• a member for .mounting said read/write heads to said actuator arm;
• a boss located on a proximal end of said member for registering with said first open slot;
• said boss swaged within said first open slot with an outer surface of said boss expanded into an inner surface of said first open slot, wherein said boss and said first open slot keep said member fixedly attached to said actuator arm;
• and
• said first open slot in said actuator arm having an opening that is smaller than a diameter of said boss.

A disk drive system comprising;

• rotatably mounted, vertically spaced apart magnetic disks, a disk motor for rotating said rotatably mounted, vertically spaced apart magnetic disks, an actuator hub, actuator hub motor, a control circuit for controlling said disk motor and said actuator hub motor to allow selective positioning of read/write heads over said rotatably mounted, vertically spaced apart magnetic disks;
• an actuator arm extending radially from said actuator hub;
• a first open slot located on a perimeter of said actuator arm, said first open slot passing through upper and lower surfaces of said actuator arm and extending into the actuator arm from a periphery thereof;
• a member for mounting said read/write heads to said actuator arm;
• a boss located on a proximal end of said member for registering with said first open slot;
• said boss swaged within said first open slot with an outer surface of said boss expanded into an inner surface of said first open slot;
• a second open slot located on said perimeter of said actuator arm, said second open slot passing through said upper and lower surfaces of said actuator arm and extending into the actuator arm from said periphery thereof;
• a second boss located on said proximal end of said member for registering with said second open slot;
• said second boss swaged within said second open slot with an outer surface of said second boss expanded into an inner surface of said second open slot;
• and
• said first open slot and said second open slot being angled away from each other, wherein said member is fixedly attached to said actuator arm.
