Abstract: A transducer suspension system has a transducer head, laminated member and a load beam. The laminated member is comprised of a support layer, at least two electrically insulating layers, and at least two electrically conducting layers. The electrical leads are formed directly into the laminated member such that each electrical lead is directly above or below at least one other electrical lead. The overlying leads have noise cancellation similar to that for twisted wire pairs. In addition, by stacking the electrical leads, more electrical leads can be accommodated in the same suspension width.

Abstract: The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.
