Abstract

A method is described to configure a single-piece flexible data cable for an actuator within a hard disk drive so that solder pads for attaching the data head lead wires are positioned on both sides of the actuator arms. Two different configurations are shown.

Flexible Data Cable for High Volumetric Density Hard Disk Drives

       A method is described to configure a single-piece
flexible data cable for an actuator within a hard disk drive so that
solder pads for attaching the data head lead wires are positioned on
both sides of the actuator arms.  Two different configurations are
shown.

      Fig. 1A shows an actuator comb for a hard disk drive and a
flexible data cable exploded outwardly beyond the ends of the arms.
Slots are provided in the cable so that the cable can slip over the
arms and attach to the hub portion of the comb.  Fig. 1B shows the
cable in place relative to the comb.  Solder pads for making
connections with the lead wires from the read/write heads (not shown)
are provided on both sides of a comb assembly.

      Fig. 2 illustrates a second configuration for a flexible data
cable that also provides solder pads to both sides of a comb
assembly.  The profile of a flat, flexible cable is shown in Fig. 2A
prior to forming.  The cable is subsequently formed as illustrated in
Fig. 2B, and is shown exploded outwardly relative to a actuator comb
in Fig. 2C.  Finally, Fig. 2D depicts the cable attached to the comb
assembly.
