Abstract

A flexible circuit construction is provided for connecting stationary electrical components to electrical components of a moving actuator within a head and disk assembly of a disk drive. The flexible circuit is integrally formed from a plastic film material carrying a plurality of metal film conductive traces and defining a plurality of regions. A connecting region has a plurality of connection pads for connecting to head conductor wires. A hairpin loop portion is provided adjacent the connecting region for reversing direction of the flexible circuit. An elongated arcuate portion leads from the hairpin loop portion to a fixed substrate portion defining plural connections for mounting a read preamplifier/write driver/head selection integrated circuit device. The connecting region defines for at least one edge region thereof a head wire tube engagement portion having a slotted opening for positioning and securing a head wire tube carrying the head wires. The connecting region includes a tab structure for engaging an adjacent portion of the moving actuator, whereby when the tab structure engages the adjacent portion, the head wire tube engagement portion is deflected into a guiding position for guiding the head wire tube toward the connection pads of the connecting region.
