When servo heads in a head chip of a servo write head assembly record servo patterns onto a tape's servo tracks, the servo heads are continuously being rapidly worn away by the tape. This general wear affects the servo heads' ability to record the servo patterns, impairing accurate positioning of the tape heads in the drive. However, by implementing, on the leading edge of the head chip, a support block that has a wear resistant skiving edge and landing zone for the tape “crow bar,” which forms when the tape is running over the servo head, the general wear of the servo heads from the tape is mitigated. The skiving edge, which may be formed by thin film technology process steps, causes the tape to fly over the head chip in those regions. An additional support block may be implemented at the trailing edge of the head chip.
