A thin film servo head apparatus is described that provides verification
of time-based servo marks on a magnetic tape. The thin film servo head
apparatus includes a plurality of thin film servo heads formed in a
substrate. The substrate is canted such that servo gaps included in each
of the thin film servo heads are substantially parallel to the time-based
servo marks. Thin film servo heads eliminate the high labor, low yield
machining process associated with conventional ferrite composite servo
heads. Thin film servo heads may be fabricated in bulk on substrate
wafers to reduce manufacturing time and cost. The invention described
herein enables thin film servo heads to be used with time-based servo
markings by defining a servo gap spacing such that when the substrate is
canted, the servo gaps of the thin film servo heads substantially align
with the time-based servo markings.
