Embodiment Construction
[0048] As described above, the boundary line detection method of the present invention can detect the boundary line between regions with different light reflection luminance with very high accuracy, so that the position of the boundary line can be determined with a size finer than the arrangement pitch of pixels. .
[0049] Furthermore, when the position determination of the magnetic head and the support member is carried out by this detection method, the position of the magnetic head main body can be determined with high precision, so that its flying distance can be stabilized.
[0050] figure 1 It is a side view showing the magnetic head position specifying device of the present invention.
[0051] This head position determination device can be used for such as figure 2 A magnetic head device such as that used in a hard disk device is shown to implement position determination.
[0052] as figure 2 As shown, this magnetic head device is composed of a magnetic head main...
