A thin film magnetic recording head utilizing a timing based servo pattern
is fabricated using a focused ion beam (FIB). The recording head is
fabricated by sputtering a magnetically permeable thin film onto a
substrate. A gap pattern, preferably a timing based pattern, is defined
on the thin film and the FIB cuts a gap through the thin film based on
that pattern. Once completed, the recording head is used to write a servo
track onto magnetic tape. The timing based servo track then allows for
the precise alignment of data read heads based on the positional
information obtained by a servo read head which scans the continuously
variable servo track.
