A magnetic media having servo track written with a thin film magnetic
recording head utilizing a servo pattern 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 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 a magnetic tape. The 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.
