Claim 17:
18. An apparatus for performing data operations on a magnetic recording tape, the apparatus comprising:
a magnetic head having at least two servo transducers positioned and configured to read parallel servo tracks extending along a longitudinal axis of the magnetic recording tape, the magnetic head also having an array of data transducers for performing data operations on the magnetic recording tape; and
a controller in communication with the magnetic head, the controller being configured to perform lateral positioning of the magnetic head relative to the servo tracks as well as perform tape dimensional stability (TDS) compensation via head skew based on signals from the servo transducer reading timing-based servo (TBS) patterns of the servo tracks, each servo track comprising a series of servo frames arranged to enable the lateral positioning of a magnetic head relative to the servo tracks and the TDS compensation via head skew, wherein each servo frame comprising a sequence of pairs of leading and trailing servo stripes, wherein midpoints between the servo stripes in each pair, at all points having a same relative lateral height on the tape, are located along a virtual median line oriented at an angle β from perpendicular to the longitudinal axis of the tape, the angle β being greater than 1 degree.
