RELATED APPLICATIONS [0001] This Application is related to U.S. patent application Ser. No. 11/252,511 by Kurita et al., filed on Oct. 18, 2005 and entitled "Method for Selectively Sensing and Removing Asperities from Hard Disk Drive Media Utilizing Active Thermally controlled Flying Heights" with attorney docket no. HSJ920040365US1, assigned to the assignee of the present invention and incorporated herein by reference as background material. [0002] This Application is related to U.S. patent application Ser. No. 11/253,102 by Kurita et al., filed on Oct. 18, 2005 and entitled "System and Apparatus for Selectively Sensing and Removing Asperities from Hard Disk Drive Media Utilizing Active Thermally controlled Flying Heights" with attorney docket no. HSJ920050160US1, assigned to the assignee of the present invention and incorporated herein by reference as background material. TECHNICAL FIELD [0003] Embodiments of the present invention relate to burnishing disks. More specifically, embodiments of the present invention relate to location specific burnishing of disks. BACKGROUND [0004] Disks are used for writing data to and for reading the data from. Disks are typically used in storage devices, such as hard disk drives (HDDs). [0005] The disk needs to be smooth in order to write data to the disk and to read the data from the disk. Disks are burnished in order to achieve a smooth surface. In the conventional art, the entire surface of a disk is burnished. Then the smoothness of the surface of the disk is evaluated. If there are any asperities, e.g., protrusions, on the disk, the entire surface of the disk is burnished again. The disks are moved back and forth between a system that burnishes and a system that evaluates the smoothness of the surface of the disk until the disk's surface passes a specified level of smoothness. SUMMARY OF THE INVENTION [0006] Various embodiments of the present invention pertain to enabling location specific burnishing of a disk. According to one embodiment, the smoothness of a disk is evaluated by gliding over a disk to determine if there is an asperity on the disk. If there is an asperity on the disk, a location of the asperity is stored to enable location specific burnishing of the disk. BRIEF DESCRIPTION OF THE DRAWINGS [0007] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention: [0008] FIGS. 1A-1D depict sliders that enable location specific burnishing of a disk, according to various embodiments of the present invention. [0009] FIGS. 2A and 2B depict sliders that have a fly height adjuster and a burnisher, according to various embodiments of the present invention. [0010] FIG. 3 depicts a slider that both enables location specific burnishing of a disk and that performs location specific burnishing of the disk, according to various embodiments of the present invention. [0011] FIG. 4 depicts a top view of a disk with locations depicted for two asperities, according to various embodiments of the present invention. [0012] FIG. 5 depicts a slider that enables location specific burnishing, according to various embodiments of the present invention. [0013] FIG. 6 depicts a slider that can be used for the purpose of burnishing asperities using location specific burnishing, according to various embodiments of the present invention. [0014] FIG. 7 depicts a computer system that controls location specific burnishing, according to one embodiment of the present invention. [0015] FIG. 8 depicts a flowchart 800 for a method of enabling location specific burnishing of a disk, according to one embodiment of the present invention. [0016] FIG. 9 depicts a flowchart 900 for a method of performing location specific burnishing of a disk, according to another embodiment of the present invention [0017] The drawings referred to in this description should not be understood as being drawn to scale except if specifically noted. DETAILED DESCRIPTION [0018] Reference will now be made in detail to various embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with these embodiments, it will be understood that they are not intended to limit the invention to these embodiments.
