Claim 4:
5. A data storage product as recited in claim 1, wherein a distance xt between topmost endpoints of each pair of servo stripes is calculated according to the following formula:, x
   t
  
  =
  
   
    L
    2
   
   -
   
    h
    ⁢
    
     tan
     ⁡
     (
     α
     )
    
   
  
 

where L is a subframe length,
h is a pattern height of the associated servo track, and
α is an equivalent azimuth angle of a nonrotated pair of servo stripes having topmost points aligned along the longitudinal axis of the tape, and bottommost points aligned along the longitudinal axis of the tape.
