Patents by Inventor Mark Mastache

Mark Mastache has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Disk drive having an improved transducer suspension assembly
    Patent number: 5579190
    Abstract: A hard disk drive having an actuator assembly in which the armstack structure comprises only load beams. The load beams are assembled by stacking on a tubular member along with the movable member of the actuator motor, or other actuator drive mechanism, and after alignment are secured to the tubular member. This actuator structure is applicable to both rotary and linear actuators in disk drives. In the rotary actuator structure, the tubular member or hub is journaled in the base of the drive for rotation about the axis of the tubular member. In the linear actuator structure, the tubular member, being fastened to the moving part of the linear drive mechanism, linearly moves with that mechanism. The load beams and the movable actuator drive mechanism are secured to the tubular member by a ball swaging operation which forcibly expands the tubular member into secure frictional engagement with the items assembled thereon to thereby integrate the assembly with a single ball swaging pass through a single member.
    Type: Grant
