J.Attorney, Agent or FirmInternational ClassG11B 005/48AbstractA head suspension has a segmented trace conductor array for electrically interconnecting a read/write head to electronic circuitry in a disk drive. Each trace segment has a predetermined generally rectangular cross-sectional area such that the intermediate first segment has a predetermined cross-sectional width greater than a predetermined cross-sectional width of an first outer segment, in order to optimize current density at very high signaling frequencies associated with information transfer between the head and the read/write circuitry. | |
