Title:
MANUFACTURING METHOD FOR LIGHT-ASSISTED MAGNETIC HEAD AND LIGHT-ASSISTED MAGNETIC HEAD
Document Type and Number:
WIPO Patent Application WO/2011/089940
Kind Code:
A1
Abstract:
Disclosed are a manufacturing method for a light-assisted magnetic head for manufacturing a high-precision light-assisted magnetic head by bonding an optical element to a slider with high precision, and a light-assisted magnetic head. Upon a slider (32), by using a mold (M10) for forming a diffraction grating (D) of an optical element (31), it is possible directly to form the optical element (31) comprising the diffraction grating (D) into a tight fit and therefore, it is possible to secure with high precision a positional relationship between the slider (32) and the diffraction grating (D) of the optical element (31) even while reducing the number of man-hours for manufacturing.
