Head slider and disk apparatus

Image Number 5 for United States Patent #6507458.

A head slider has a chamfered pad between the side edge and rail at the surface opposing the disk. The pad prevents contact between the edge of the basic material of the head slider and the disk. Contact between the pad and disk can be generated, but since the pad is chamfered, the disk is not as easily damaged. In comparison with chamfering the basic material and rail, the present invention has less influence on the floating characteristics of the slider, so the amount of chamfering can be increased. Therefore, damage to the disk can be alleviated remarkably and shock resistance of disk apparatus can be much improved.
