    Abstract: According to one embodiment, a stopper of a disk device includes a fixing member to be fixed to a supporter of the disk device, and a cushioning member formed of a fluorine rubber and attached to the fixing member. The cushioning member includes a contact surface which contacts the fixing member, a first contact surface which can contact the supporter of the disk device, and a second contact surface which can contact a movable member in the disk device, the first contact surface has a first surface adhesive force based on adhesion of the fluorine rubber, and the second contact surface is subjected to a non-adhesive surface treatment and has a second surface adhesive force which is less than or equal to 1/20 the first surface adhesive force.

    Abstract: A read/write head has an input coupler that receives light at a fundamental mode from an energy source. A mode converter of the read/write head converts light from the fundamental mode to a higher-order mode. The read/write head has a bent waveguide coupled to the mode converter at an interface. The bent waveguide includes a curve with a taper. The taper nullifies the fundamental mode generated in the curve and recovers the higher-order mode at an output of the bent waveguide. A near-field transducer that receives the output of the bent waveguide is offset from the facet of the input coupler in a cross-track direction.

    Abstract: Alignment of a near field transducer (NFT) optical input coupler and a light emitting device involves providing excitation radiation from an excitation light source through an optical input coupler to the NFT and filtering output radiation from the NFT using a short wavelength pass optical filter. The optical input coupler is scanned through multiple positions while the photoluminescent radiation is detected. A first alignment position between the NFT input coupler and the excitation light source is identified based on the detected photoluminescent radiation. A light emitting device is scanned through multiple positions the light output is detected by a detector. A second alignment position between the light emitting device and the detector is identified. The first and second alignment positions are used to align the light emitting device with the optical input coupler.
