ABSTRACT:
A tape head assembly for use in conjunction with a magnetic recording tape has a support structure, an island affixed to the support structure, and a transducer located on the island. The island has at least two sections of differing widths parallel to the direction of tape operation. The transducer is located in the wider section. The island is susceptible to wear as the magnetic recording tape streams across the island, such that the height profile of the island in a direction perpendicular to the direction of a tape operation varies over time. The island experiences substantially uniform wear at a substantially nonuniform height profile, and substantially nonuniform wear at a substantially uniform height profile.
