Divided Actuator Arm for High Density Hard Disk Drives

       Disclosed is an Actuator Arm Structure used in Hard Disk
Drives to reduce disk to disk spacing.

      This Actuator Arm Structure consists of two different Actuator
Arms.  One Actuator Arm has only UP type Head Suspension Assemblies
shown in Fig. 1, and the other Actuator Arm has only DOWN type Head
Suspension Assemblies shown in Fig. 2.

      Assembly sequence is as follows:
      1.  Combine both Actuator Arms into one (Fig. 3).
      2.  Insert them into a Pivot Shaft.
      3.  Merge Head Suspension Assemblies attached on one Actuator
Arm on the Disk surfaces.
      4.  Merge Head Suspension Assemblies attached on the other
Actuator Arm on the Disk surfaces.
      5.  Align these Actuator Arms.
      6.  Fix them into one by using screws, welding, bonding and so
on.

      Because we can merge DOWN and UP type Head Suspension
Assemblies separately, we can eliminate the dead space for Head
Suspension Assemblies lift when merging.  Thus, disk to disk spacing
is reduced.
