  • Detection of track misregistration within user data channel
    Patent number: 7009805
    Abstract: A method for computing position error signal information of a transducer in a data storage system provides for different readback signals between adjacent tracks. The method involves a computation to obtain coarse position information from the servo bursts signals for track seeking and a computation to obtain a position indicator from the user data sector for more precise track following within the user data sector.
    Type: Grant
