  "title": "Removable ball staked head gimbal assembly",
  "abstract": "In a magnetic head carrying device a method and apparatus for removing a magnetic head carrying arm from a support arm wherein ball stake mounting is used to affix the magnetic head carrying arm to the support arm. A mounting plate is provided having a bevel. Tool blades may be inserted into the bevel to disassemble the ball stake mount.",
  "claims": [
    "1. A magnetic transducer support comprising: a support arm including a hole defined in the support arm creating a first passageway therethrough; a transducer carrying arm having a hole therein for creating a second passageway therethrough; a ball stake connector for fixedly mounting the support arm to the transducer carrying arm, the ball stake connector including a mounting plate joined to the carrying arm and sandwiched between the carrying arm and the support arm, and a tubular member extending from the mounting plate into the first passageway for ball staked connection to the support arm; and opposing surfaces of the support arm and the mounting plate defining tool insertion gaps between the transducer carrying arm and the mounting plate for use in disengaging the ball stake connector, wherein the tool insertion gaps are positioned on opposite sides of the mounting plate to receive a tool and wherein the opposing surfaces receive a separation force from the tool to cause separation of the ball stake connector and the support arm.",
    "2. A magnetic transducer assembly comprising: a flat arm carrying a magnetic transducer head; a second arm having a hole therein mounted to the first arm; a mounting plate joined to the first arm and sandwiched between the first and second arms, said mounting plate having a tubular member extending therefrom and into said hole, said tubular member being ball staked into engagement with said second arm; and opposing surfaces of said mounting plate and said second arm defining a plurality of beveled surfaces for engaging a disassembly tool and receiving disassembly forces therefrom.",
    "3. The assembly of claim 2, wherein the mounting plate has four corners, each corner having one of said beveled surfaces.",
    "4. An apparatus in a magnetic storage system comprising: a first arm which carries a magnetic transducer at one end and includes an aperture a the other end; a mounting plate coupled to the first arm, the mounting plate including a mounting plate face and an elongated hollow member aligned with the first arm aperture; and a second arm connected to an E-block assembly, the second arm including an aperture and a second arm face, the second arm aperture aligned with the first arm aperture and the elongated hollow member, wherein a portion of the second arm face is in abutting contact with the mounting plate face and a portion of the second arm face is spaced apart from the mounting plate face to receive a disassembly tool, and to receive disassembly forces from the tool for separating the mounting plate and the second arm."
