Abstract: A transducer (48) for a hard disk drive has a magnetic core (66) and a pair of poletips (44) that project transversely from the core for sliding contact with the disk during reading and writing. The transducer is formed entirely of thin films in the shape of a low profile table having three legs that slide on the disk, the poletips being exposed at a bottom of one of the legs for high resolution communication with the disk, the throat height of the poletips affording sufficient tolerance to allow for wear. The transducer includes a loop shaped core of magnetic material that ends at the poletips, the core extending further parallel than perpendicular to the disk surface. The dimensions of the yoke adjacent to the poletips are designed to avoid saturation at the poletips by saturating at a lower flux in the yoke than the poletips.
