摘要： A magnetic head structure has a coil and a magnetic pole allowing a magnetic flux generated by the coil to be transmitted therethrough and forming a magnetic gap. An insulating layer surrounds the coil, and a protective layer covers the insulating layer and the magnetic pole. The insulating layer has a volume equal to or greater than a value which is determined with respect to a thickness of the protective layer. It is preferable to increase the volume of the insulating layer as the thickness of the protective layer is made greater. By increasing the volume of the insulating layer, the protrusion of a portion of a floating surface of the magnetic head slider near the magnetic pole, toward the disk, is reduced.

摘要： A method for manufacturing a head stack assembly that includes a pair of suspensions each of which supports a head, an arm that drives the head, and a pair of base plates that attach the pair of suspensions to both sides of the arm that has a perforation hole, each of the pair of base plates having a boss with an opening includes the step of swaging the pair of base plates with the arm by passing, in one direction, a processing member larger than the opening through the perforation hole and the base plates while the pair of base plates are being inserted into the perforation hole at both sides of the perforation hole, wherein where a neutral plane is defined as a plane that halves a thickness of the arm and is perpendicular to a section that includes a center axis of the perforation hole, a first position is defined as a position that has a minimum internal diameter of the base plate, and a second position is defined as a position closest to the neutral plane among contact positions between the base plates and the arm, a distance between the neutral plane and the first position is equal to or smaller than a distance between the neutral plane and the second position before the swaging step.

摘要： A head slider is related to an actuator block. A flexible printed circuit board is received on the surface of the actuator block. A head IC is mounted on the surface of the flexible printed circuit board. A heat conductive member is mounted on the head IC. The heat resistance of the heat conductive member is set smaller than that of the flexible printed circuit board. A larger amount of heat can be transmitted from the head IC to the actuator block. The actuator block is made of a metal material such as aluminum. The heat resistance of the actuator block is apparently smaller than that of the flexible printed circuit board. A larger amount of heat can be radiated from the actuator block as compared with the flexible printed circuit board. The head IC is thus reliably prevented from a rise in the temperature.

摘要： A collapsible lens barrel is provided, including a mechanism capable of reliably inhibiting rotation of a rotational barrel even if any impact is applied thereto, for example, due to a fall with the barrel being extended. When the rotational barrel is pressed upon a fixed member due to impact in defiance of the biasing force of a wave spring, a first engagement portion provided at a camera body-side end of the rotational barrel engages with second engagement portions provided on a subject-side surface of the fixed member, which locks rotation of the rotational barrel, thereby making it possible to prevent gears from being damaged, for example.
