Patent ID: 7561367

Claim:
A disc sweeping method comprising: rotating a data storage disc at a speed sufficient to generate a fluid flow that supports a transducer at a desired spatial separation from the data storage disc; during the rotating step, beginning a sweep routine of the transducer, along a sweep path and in accordance with a velocity profile that are both predefined before the beginning the sweep routine, by moving the transducer to a first track of the data storage disc that is predefined by the sweep path; during the rotating step and after completing the moving the transducer to the first track step, accelerating the transducer from the first track radially inward to a second track of the data storage disc that is predefined by the sweep path, at an acceleration rate that is predefined by the velocity profile; during the rotating step and after completing the accelerating the transducer from the first track step, moving the transducer to a third track of the data storage disc that is predefined by the sweep path, the third track being disposed neither radially between the first and second tracks nor consecutive to either of the first or second tracks; and during the rotating step and after completing the moving the transducer to the third track step, accelerating the transducer from the third track radially outward to a fourth track of the data storage disc that is predefined by the sweep path, at an acceleration rate that is predefined by the velocity profile, thereby ending the sweep routine.
