摘要： An optical head includes a lens carrier movable at least radially of a magneto-optical disk in facing relation thereto. An object lens is mounted on the lens carrier to converge a laser beam for forming a laser spot on the disk. The object lens has an optical axis and includes a lens surface directed toward the disk. A patterned coil is formed on the lens surface at least in one layer and has a light-passing opening corresponding to the optical axis of the object lens. A light-pervious layer is formed on the lens surface for closing the light-passing opening of the coil.

摘要： An optical head includes a lens holder for carrying a biconvex lens and a plano-convex lens above a data storage disk. In data-writing or data-reading operation, the plano-convex lens comes closer to the storage disk than the biconvex lens. The plano-convex lens is accommodated in a through-hole formed in the lens holder. The lower opening of the through-hole is closed by a transparent plate attached to the bottom surface of the lens holder. The flat lens surface of the plano-convex lens is held in close contact with the transparent plate.

摘要： An air-bearing head slider for supporting an electromagnetic transducer opposite to a rotating recording media or magnetic disk. A slider body has a surface having a leading or air-entry side and a trailing or air-delivery side. Two rails are provided on the surface of the slider body and has floating surfaces opposite to the rotating magnetic disk for generating a floating force. The two side rails extend along a direction of air flow generated by the rotation of the magnetic disk and define a relatively shallow groove between these two rails. The groove has a width-enlarged portion at which the width of the groove is enlarged, so that a negative pressure is generated in such a manner that the slider body is attracted to the rotating magnetic disk. Inclined surfaces are formed on the air-entry sides of the floating surfaces of the rails. An inclination angle of the inclined surface is not more than 3.degree. and not less than 0.5.degree. and a length of the inclined surface is not less than 50 .mu.m and not more than a half of a length of the rails in the direction of air flow.

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)
