| 20090052086 | METHOD OF MAKING HEAD SLIDER AND RESULTANT HEAD SLIDER - A laser beam is radiated to the corner of the back surface of the head slider having the front surface defining a medium-opposed surface. This method employs a laser beam radiated to the corner of the back surface of the head slider. The material thus gets molten at least partly at the corner of the head slider. The molten material then gets cured or hardened. The corner of the head slider warps back. The corner of the medium-opposed surface is in this manner chamfered. The shape of the chamfer can clearly be observed. Such chamfering process can be repeated until a desired shape is obtained. In this manner, the head slider can readily be chamfered with a high accuracy. | 02-26-2009 |

| 20090168261 | HEAD SLIDER AND MAGNETIC STORAGE DEVICE - A magnetoresistive element is located between a lower shielding layer and an upper shielding layer. The magnetoresistive element receives an electric current through the lower shielding layer and the upper shielding layer. A non-magnetic conductive layer is embedded in the insulating film between the slider body and the lower shielding layer. An air layer is formed between the head slider and a storage medium. Capacitive coupling is established between the head slider and the storage medium. The capacitive coupling allows transmission of the noise from the storage medium to the slider body. The noise affects capacitance established between the lower shielding layer and the slider body. The non-magnetic conductive layer serves to prevent variation in a potential difference resulting from transmission of the noise between the lower shielding layer and the upper shielding layer. | 07-02-2009 |
