Abstract

This article describes a method for reducing the bias force that is caused by the influence of a flexible cable in a compact hard disk. This method is that head wires are directly connected to a card through the center of a pivot shaft of an actuator. This actuator assembly has no flexible cable and, thus, is not influenced by the flexible cable bias force.

Actuator Assembly in Compact Hard Disk Drive

This article describes a method for reducing the bias force that is caused by the influence of a flexible cable in a compact hard disk. This method is that head wires are directly connected to a card through the center of a pivot shaft of an actuator. This actuator assembly has no flexible cable and, thus, is not influenced by the flexible cable bias force.

The construction of this actuator assembly is shown in Figs. 1, 2 and 3.

The manufacturing steps of this actuator assembly are as follows.
1. Hollow out the center of a pivot shaft and pass

lead wires through a hole.
2. Clip two head wire tubes with wire support; fix it

in the pivot shaft.
3. Insert RTV rubber into the hole so air does not leak

out from the shaft.
4. Solder the head wires directly on a card.
