摘要： A suspension for supporting a head slider has a flexure, several trace patterns positioned on the flexure, front flexure-bonding pads disposed on the flexure at a position corresponding to a leading edge of the head slider and connected to the trace patterns, and rear flexure-bonding pads disposed on the flexure at a position corresponding to a trailing edge of the head slider and connected to the trace patterns. The front and the rear flexure-bonding pads and the trace patterns are integrally formed and disposed on the flexure at the same time, so the fabricating process is simplified and there is no alignment problem for bonding location. This can ensure the connection strength and position between the head slider and the suspension changeless and, in turns, ensure a good attitude of the head slider. The invention also discloses a HGA and a disk drive device with such suspension, and a fabricating method for the suspension.

摘要： A head gimbal assembly (HGA) has an improved interconnection between a head slider and a suspension of the HGA. The interconnection is achieved by using a reverse surface of an air bearing surface of the head slider as bonding surface to provide more space for arranging more slider electrical bonding pads thereon. The head slider is mechanically and electrically connected to the suspension at the bonding surface to have good performance on shocking conditions. The suspension further has an attitude control layer located between the head slider and the suspension. The attitude control layer serves as a datum plate for the head slider lying thereon and supporting the head slider so as to ensure the head slider a good attitude and reduce variation of slider flying height. The present invention also discloses a magnetic disk drive with the improved HGA and a fabricating method for the HGA.
