Patent number: 8416648Abstract: Producing a servo pattern on a media involves rotating a master, and during a first revolution of the master, forming a first transition at a first radial position on the master, and forming a first transition at a second radial position. During a second revolution of the master, a second transition at the first radial position is formed, and a second transition at the second radial position is formed. By exposing individual servo burst transitions located at the first and second radial positions, in separate disk revolutions, only one of the magnetic transitions will inherit a particular deflection from a nominal radial position. If there are any mechanical disturbances, each magnetic transition will be randomly displaced from its nominal position, reducing the written-in run-out by ?n, where n is the number of magnetic transitions in a particular servo burst.Type: GrantFiled: August 31, 2010Date of Patent: April 9, 2013Assignee: Seagate Technology LLCInventors: Gabor Szita, Koichi Wago, Neil Deeman
