Abstract: According to one embodiment, a suspension assembly including a load beam and an electric wiring member is provided. The load beam has a thin plate-like shape that extends from a base part toward a distal end. The electric wiring member extends from the base part toward the distal end to be overlapped with a first surface of the load beam and includes a wire formed thereon. A protrusion that protrudes on the first surface side is provided at a position avoiding the electric wiring member on the load beam, as seen in a plan view.

Abstract: According to one embodiment, a head assembly manufacturing apparatus for manufacturing a head assembly including a load beam having a protrusion and a gimbal in contact with the load beam at the protrusion, includes: a heater configured to heat the protrusion from a back surface of the load beam; a thermal image forming module configured to form a first image which is a temperature distribution image of the gimbal by detecting infrared radiation emitted from a front surface of the gimbal; and a position detector configured to detect a position of the protrusion on the gimbal based on the first image formed by the thermal image forming module.

Abstract: Provided is a compact inexpensive optical disk drive adaptable to high-density optical disks and having an improved stationary optical unit. The storage device has a first light path and a second light path defined therein. Along the first light path, laser light emanating from a laser light source is passed through a collimator lens and a beam splitter and routed to a movable optical system that is movable on an optical disk. Along the second light path, light reflected from the optical disk and returned from the movable optical system is split into a plurality of rays by the beam splitter, and one of the rays is routed to a sensor via a servo unit and a condenser. An angle at which the second light path meets the first light path is 90°+&agr;° where &agr; denotes a positive number.

Abstract: There is disclosed a storage apparatus which is of a system of utilizing a polarized state change by Kerr effect to read information from a storage medium and which easily and precisely performs adjustment to compensate for a phase deviation between both P, S polarized components attributed to an optical system. Phase plates 500, 510 are disposed between a fixed optical section 200 and a movable optical section 190 and the inclination angles of the phase plates are adjusted.
