Title:
SUBSTRATE FOR MAGNETIC HEAD SLIDER AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/102621
Kind Code:
A2
Abstract:
The present invention relates to a substrate for a magnetic head slider and a manufacturing method thereof. More particularly, the present invention relates to a substrate for a magnetic head slider having an optical waveguide through which a light source of a laser and the like can pass and a manufacturing method thereof. According to the present invention, the substrate for the magnetic head slider comprises: a substrate having a first surface, a second surface parallel to the first substrate, and a through-hole which passes through the first and second surfaces; and an optical waveguide formed in the though-hole. The substrate for the magnetic head slider according to the present invention can transfer the light energy of the light source of the laser and the like to a magnetic disk through the optical waveguide formed on the substrate. Accordingly, the substrate for the magnetic head slider according to the present invention enables the improvement of the recording density and the data recording and replay speed of the hard disk by irradiating the laser light source and the like on the slider to heat the surface of the magnetic disk.
