    摘要: Disclosed is a method of polishing a magnetic head slider whereby a by-processed step can be easily reduced. An air bearing surface of the magnetic head slider is polished with setting a bar that includes the magnetic head slider where a thin film magnetic head element is formed to reciprocate in a radius direction of a polishing plate, as well as rotating the polishing plate having a polishing surface. Polishing steps include a first polishing step of performing a height polish while rotating the polishing plate at a first velocity, and a second polishing step of performing a finishing polish while rotating the polishing plate at a second velocity sufficiently lower than the first velocity. The second velocity at the second polishing step is set so that an average linear velocity in the direction of the rotation of the polishing plate is equal to or lower than 0.032 m/s (preferably equal to or lower than 0.008 m/s). Consequently, the by-processed step that is generated on the air bearing surface of the magnetic head slider is reduced.

    摘要: Provided are a method and an apparatus for manufacturing a magnetoresistive element and a method and an apparatus for manufacturing a magnetic head which can reduce variation in properties of an magnetoresistive element and variation in the median of distribution.Before starting polishing, wafer information containing various types of factors in a wafer stage which may have an influence on a resistance value of a final MR film is obtained, and an S value is calculated from the information by using a statistical scheme. During a polishing step, ongoing-work-information containing various types of factors in a polishing stage which may have an influence on the resistance value of the final MR film is obtained at regular intervals. A K value is calculated from the information by using the statistical scheme. Then, an MR resistance estimate during the polishing step is calculated from the S value and the K value. When the MR resistance estimate reaches a target resistance value , polishing is stopped.

    摘要: When electric elements are formed on a ceramic bar or the like, the positional displacement of the respective elements occurs due to a division exposing process or the like. An object of the present invention is to provide a device and a method which unify the non-polished portion of the respective elements by conducting polishing while a complicated deformation or the like is given to the ceramic bar. To achieve this object, the ceramic bar or like is held by using a jig, and a plurality of loads are applied to portions of the jig where the ceramic bar or the like is held, to thereby deform the ceramic bar or the like and polish the element in that state. In this situation the load applied points are disposed so as to avoid the boundaries of the division exposure.

    摘要: In a surface light source device (1), a positive reflective region (23) of a reflective member (20) that is disposed on the bottom surface (4) of a housing (2) reflects light output by a light emitting device (14) toward a direction away from the light emitting device (14). As a result, the brightness of the light in the proximity of the light emitting device (14) of the surface shaped illuminating light output by a light emitting surface member (3) can be suppressed, and the brightness of light of a central part (position furthest away from the light emitting device (14)) of the surface shaped illuminating light output by the light emitting surface member (3) can be increased.
