Abstract

A servo head capable of verifying at least one timing based pattern printed on media is provided. The servo head includes a magnetic structure having at least one magnetic element arranged and configured to form at least one magnetic gap parallel to the timing based pattern. In one embodiment, the magnetic element is arranged and configured to have a plurality of magnetic gaps being parallel to each other but not co-linear to each other. In the second embodiment, the magnetic element is arranged and configured to have a magnetic gap being parallel to and co-linear to the timing based pattern.

Claims

exact text as granted — not AI-modified
1 - 39 . (canceled)  
   
   
       40 . A servo head capable of writing a portion of a timing based pattern comprising at least two magnetic writing gap elements, wherein the at least two magnetic writing gap elements are parallel and co-linear.  
   
   
       41 . The servo head of  claim 40 , wherein the at least two magnetic writing gap elements are substantially aligned to a predetermined angle with respect to the direction of a magnetic media velocity.  
   
   
       42 . The servo head of  claim 40 , wherein the servo head further comprises at least one thin film head row bar comprising the at least two magnetic writing gap elements.  
   
   
       43 . The servo head of  claim 40 , wherein the servo head further comprises at least one magnetic gap bar comprising the at least two magnetic writing gap elements.  
   
   
       44 . The servo head of  claim 40 , wherein the servo head comprises a plurality of magnetic writing gap elements.  
   
   
       45 . The servo head of  claim 40 , further comprising at least one additional gap element, wherein the at least two magnetic writing gap elements are substantially aligned to a predetermined angle with the at least one additional gap element.  
   
   
       46 . The servo head of  claim 40 , wherein the timing of energizing the at least two magnetic writing gap elements is staggered to produce an arbitrary pattern of magnetic transitions on magnetic media.  
   
   
       47 . The servo head of  claim 45 , wherein the timing of energizing the gap elements is staggered to produce an arbitrary pattern of magnetic transitions on magnetic media.  
   
   
       48 . A servo head capable of writing a portion of a timing based pattern comprising at least two magnetic writing gap elements, wherein the at least two magnetic writing gap elements are parallel and not co-linear.  
   
   
       49 . The servo head of  claim 48 , wherein the at least two magnetic writing gap elements are substantially aligned to a predetermined angle with respect to the direction of a magnetic media velocity.  
   
   
       50 . The servo head of  claim 48 , wherein the servo head further comprises a thin film head row bar comprising the at least two magnetic writing gap elements.  
   
   
       51 . The servo head of  claim 48 , wherein the servo head further comprises a magnetic gap bar comprising the at least two magnetic writing gap elements.  
   
   
       52 . The servo head of  claim 48 , wherein the servo head comprises a plurality of magnetic writing gap elements.  
   
   
       53 . The servo head of  claim 48 , further comprising at least one additional gap element, wherein the at least two magnetic writing gap elements are substantially aligned to a predetermined angle with the at least one additional gap element.  
   
   
       54 . The servo head of  claim 48 , wherein the timing of energizing the at least two magnetic writing gap elements is staggered to produce an arbitrary pattern of magnetic transitions on magnetic media.  
   
   
       55 . The servo head of  claim 53 , wherein the timing of energizing the gap elements is staggered to produce an arbitrary pattern of magnetic transitions on magnetic media.  
   
   
       56 . Magnetic media made with a servo head capable of writing a portion of a timing based pattern comprising at least two magnetic writing gap elements, wherein the at least two magnetic writing gap elements are parallel and co-linear.  
   
   
       57 . The magnetic media of  claim 56 , wherein the magnetic media is magnetic tape.  
   
   
       58 . Magnetic media made with a servo head capable of writing a portion of a timing based pattern comprising at least two magnetic writing gap elements, wherein the at least two magnetic writing gap elements are parallel and not co-linear.  
   
   
       59 . The magnetic media of  claim 58 , wherein the magnetic media is magnetic tape.
