Abstract: A magnetic head includes a slider having a thin-film magnetic element disposed at a trailing end of a surface of the slider opposite a magnetic recording medium. The slider has side surfaces that may be substantially perpendicular to the surface opposite the recording medium and may extend in a direction in which the slider moves relative to the recording medium and inclined surfaces disposed between the surface opposite the recording medium and the side surfaces. The inclined surfaces may form obtuse angles with the surface opposite the recording medium and the side surfaces.

Abstract: A sliding resistance member (3) is interposed between a glove box (B) and a rod type air damper (21). It is assumed that when a glove box lid (L) corresponding to a open-close member starts opening, the rod type air damper (21) rotates while running idle in conjunction therewith, in a relation in which the rotary type oil damper (3) is positively interposed between the glove box (B) corresponding to the mounting shaft and the rod type air damper (21). However, since a braking force of the sliding resistance member (3) is applied to the side of the open-close member in a rotating section of the rod type air damper (21), an sufficient damper effect can be obtained even when the open-close member starts opening.

Abstract: A tubular cylinder has a first end and a second end. A piston is movable in the cylinder. A compressed coil spring resiliently biases the piston toward the first end of the cylinder. A string transmits a damper function, caused by a movement of the piston, to a body to be moved. The string slideably wraps over the piston, and extends the length of the cylinder.

Abstract: A crown forming method of forming a crown on a floating type magnetic head which includes the steps of placing an approximately rectangular-prism-shaped bar, which has magnetic head elements of not less than 1 formed on a side wall thereof in a row, on the convex surface of a jig whose radius of curvature is R1 through an elastic sheet while facing the surface to be processed of the bar to a lapping surface plate having a concave processing surface whose radius of curvature is R2 with the relationship between the radius of curvatures set to R1≧R2, deforming the bar to an arc shape along the longitudinal direction thereof and bonding it on the convex surface together with the elastic sheet, and lapping the surface to be processed by abutting it against the processing surface and moving the surface to be processed relative to the processing surface.

Abstract: A sizing lapping apparatus includes a rotatably provided disk-shaped lap plate for supplying a lapping liquid thereto; at least one holding portion for holding a workpiece, the at least one holding portion being used to press the workpiece against the lap plate; a support shaft, provided in an erected state with respect to the lap plate, for supporting the at least one holding portion; an oscillating mechanism for causing the support shaft to undergo oscillatory rotational motion around an axis thereof; a base for supporting the support shaft so that the support shaft freely rotates around the axis thereof; and a base rocking mechanism for reciprocating the base in a diametrical direction of the lap plate or in a direction substantially parallel to the diametrical direction. The sizing lapping apparatus can carry out lapping operations with very high precision. This is made possible by partly adjusting the amount by which the workpiece is lapped, in accordance with the lapping state of the workpiece.

Abstract: Employed is a crown forming method of forming a crown on a floating type magnetic head which includes the steps of placing an approximately rectangular-prism-shaped bar, which has magnetic head elements of not less than 1 formed on a side wall thereof in a row, on the convex surface of a jig whose radius of curvature is R.sub.1 through an elastic sheet while facing the upper surface (surface to be processed) of the bar to a lapping surface plate having a concave processing surface whose radius of curvature is R.sub.2 with the relationship between the radius of curvatures set to R.sub.1 .gtoreq.R.sub.2, deforming the bar to an arc shape along the longitudinal direction thereof and bonding it on the convex surface together with the elastic sheet, and lapping the upper surface (surface to be processed) by abutting it against the processing surface and moving the upper surface (surface to be processed) relative to a processing surface.

Abstract: The present invention provides a magnetic head including a slider 1 and a thin-film element 3, a magnetic recording/reproducing apparatus including the same, and a method for manufacturing the same. According to the present invention, since a resist layer is formed on the thin-film element 3 prior to a milling process, the thin-film element can be protected from the influence of the milling process, and generation of an element recess can be inhibited. Further, since the slider 1 is preferably formed of a ceramic composition including Al.sub.2 O.sub.3 and TiC, the roughness can be readily adjusted by the milling process. Moreover, when the center line mean roughness of each opposing surface 5 of the slider, said surface opposing the recording medium, is represented by R.sub.ah1 and that of the disk serving as the recording medium is represented by R.sub.ad, the relationship, 6 nm.ltoreq.R.sub.ah1 +R.sub.ad .ltoreq.19 nm is preferably satisfied.
