Abstract
A method and system in accordance with the present invention for minimizing the loss of data by a write head is disclosed. The method comprises providing a desired write head width based upon a hard error rate. The method further comprises adjusting at least one parameter of the servo control logic based upon a comparison of the width of the write head and the desired write head width, wherein the write head will not exceed the hard error rate when writing data. Through the use of a system and method in accordance with the present invention a servo system can be designed based on a constant hard error rate. The write inhibit window and the settle delay for writing operations in a servo system will be optimized, based on the hard error rate, for each individual head in the disk drive configuration. This will increase the speed of the servo process without affecting the reliability of the data.
