Problems solved by technology

[0009] However, in the conventional machining process, in the final cutting with a grindstone of a single cutting slider, since the angle formed by the step surface and the side surface is 90°, chipping, Burrs, etc., or threshing, become the cause of damage to the disk surface
In addition, even in the inspection process, the yield rate decreases due to debris on the cut surface, etc.

Embodiment Construction

[0033] figure 1 It is a perspective view showing the magnetic head according to the embodiment of the present invention mounted on a hard disk or the like with the recording medium facing surface facing upward. figure 1 The slider 11 of the shown magnetic head is made of a ceramic material such as alumina, titanium carbide, or silicon, and an air groove 12 is formed on the surface facing the recording medium, and rail portions 13a, 13b are formed around the air groove 12 .

[0034] The surroundings of the rail portions 13 a and 13 b form a recording medium facing surface 14 that faces a recording medium that is formed on the same plane as the air groove 12 . In addition, in the present invention, two rail portions 13a, 13b are formed, but the number and shape of the rail portions 13a, 13b are not limited to figure 1 Quantity, shape shown.

[0035] On the rear end surface (end) B of the slider 11, a thin-film magnetic element 15 adjacent to the recording medium facing surf...

Abstract

A magnetic head and its manufacturing method. The 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.

Description

technical field [0001] The present invention relates to a slider of a magnetic head mounted on, for example, a hard disk device, and more particularly to a magnetic head having a predetermined side shape of a slider and a method of manufacturing the same. Background technique [0002] In conventional magnetic head sliders mounted on conventional hard disk devices, etc., a plurality of thin-film magnetic head elements are formed on a substrate, and then the substrate is diced to form rod-shaped chip strips (element arrays), and the cut surfaces are subjected to predetermined polishing. . On the surface of the chip bar that becomes the trailing end of each slider, a plurality of magnetic recording and / or reproducing devices are provided adjacent to the recording medium facing surface (ABS surface) facing the magnetic recording medium. thin film magnetic components. By processing this chip bar, sliders for a plurality of magnetic heads having a track pattern of a predetermine...
