Patent ID: 7593188

Claim:
A magnetic head slider configured to move over a magnetic disk to write data thereto and read data therefrom, the disk being capable of generating an air flow between the disk and the slider during operation, the magnetic head slider comprising: at least one front pad formed on an upstream portion of the slider and operative to generate a lifting force by use of the air flow; a rear pad located downstream of said front pad and along a longitudinal axis of the slider and including a load-carrying part for generating a lifting force by use of the air flow and a head mounting part that is separated from said load-carrying part by a groove formed therebetween, said load-carrying part having a transverse width of a first dimension and a downstream edge including a concave portion facing said head mounting part and defining one side of said groove, said head mounting part having a transverse width of a second dimension substantially smaller than said first dimension and including a heat source for generating heat energy in said head mounting part to cause a protrusive deformation of said head mounting part in the direction of the disk, and wherein said groove tends to thermally isolate said head mounting part from said load-carrying part and prevent said heat energy from deforming said load-carrying part.
