Abstract
An example embodiment provides for an apparatus and method, for use in a tape drive system, that supplies tape azimuth error information transduced from servo read elements that are located on differing bumps of a magnetic read/write head. Non-azimuth error information is also transduced from servo read elements located on a read bump. The azimuth error and non-azimuth are utilized to correctly place the magnetic head at a currently selected track of the tape for which data is being written. In one implementation, the servo read elements utilized for transducing the azimuth information are substantially aligned with each other relative to a tape path and disposed on separate bumps. In another implementation, the servo read elements utilized for transducing the azimuth information are not substantially aligned with each other and are disposed diagonally on opposite bumps.
