Abstract
A method of setting write factors of each head in a hard disk and a hard disk drive using the method. The method includes writing a write signal onto a test track based on a write factor initially set on the magnetic head, writing the write signals onto the tracks adjacent to the test track, measuring the write quality of the test track, changing the write factor of the magnetic head and repeating the writing of the write signal onto the test track, and setting a write factor of the magnetic head by selecting the write factor corresponding to an optimum write quality from among the write qualities of the write factors of the test track.
