    摘要: An optical information recording/reproducing apparatus records information on and/or reproduces information from an optical recording medium based on a reflected light beam from the optical recording medium. The apparatus includes a light splitting part having a plurality of light splitting stages which split the reflected light beam from the optical recording medium into a plurality of light beams, and a photodetector unit including a plurality of photodetectors which receive the plurality of light beams from the light splitting part. The photodetector unit includes a plurality of photodetectors which receive light beams used to detect a focal error, at least one photodetector which receives a light beam used to detect a tracking error, and a plurality of photodetectors which receive light beams used to detect magneto-optic information recorded on the optical recording medium.

    摘要: A floating slider (1) includes an opposing face (11) opposed to a storage medium (Dc). The opposing face (11) has a crown surface (7) like an outer columnar surface having an axis extending radially of the storage medium. The floating slider (1) is floated off the storage medium (Dc) by air flowing in between the storage medium (Dc) and the opposing surface (11). In the floating slider (1), the following expression is satisfied where d represents a crown thickness defined as a distance from an vertex of an arc in a section of the crown surface (7) to a chord of the arc, and L represents a slider length defined as a length of the opposing face parallel to the chord: 250(nm/mm)×L(mm)≦d(nm)≦250(nm/mm)×L(mm)+1500(mm)
