ABSTRACT:
An apparatus and method is provided for storing and retrieving information from a disk in which a TPI (tracks per inch) profile of a disk drive including a write pole having a trapezoidal cross-section is adaptively varied. The method includes comparing the slope angle of sides of a write pole associated with a magnetic head to a skew angle associated with a disk area; and dividing the disk areas into a first area in which the slope angle is greater than the skew angle and a second area in which the slope angle is not greater than the skew angle. Based on this comparison result, different track pitches for the first area and the second area are determined.
