ABSTRACT:
A magnetic head, and method of its construction, for placing multiple, high tolerance servo information tracks in evenly spaced configuration across the width of a magnetic medium in a single pass of the magnetic head over the medium. The head comprises a monitoring fixture which secures a full-width write transducer, in tandem with a multiple-track write transducer. Preferably, the transducers are angularly skewed with respect to the travel direction of the magnetic medium, but are substantially parallel to each other. In operation, the magnetic medium first passes adjacent the full-width write transducer which writes a servo pattern across the width of the magnetic medium at a first frequency. The magnetic medium next passes adjacent the multiple-track write transducer which writes servo information onto multiple tracks in the magnetic medium at a second frequency.
A method for constructing the magnetic head is disclosed, including the method of constructing the multiple track write transducer, and the method of determining the desired angular orientation of the transducers as they are affixed in the housing with respect to travel direction of the magnetic medium.
