Abstract:
A method for enabling correct placement of a read-write head of a disk drive having a disk storage medium with a servo track and a data area, said method comprising:calculating a series of values for an integral parameter to be utilized within a servo-positioning analysis that positions said read-write head during operation of said disk drive, wherein each value of said series of values represents a particular off-set for a respective servo track at which said value is calculated; evaluating a respective offset constant that is added to said integral parameter when said value of said integral parameter falls outside of a particular range required to ensure that said servo positioning analysis provides a correct placement of said read-write head; and storing said integral parameter along with said respective offset constant, wherein said values are later retrieved and utilized to complete said servo-positioning analysis to enable substantially correct placement of said read-write head.
