Abstract	A one-sided MIG (metal-in-gap) head is proposed for perpendicular recording on single-layer Co-Cr layers. When the recording current is sufficiently high, saturation sets in at the pole tip at the ferrite side of this head, while the sendust side is still recording well. This results in an asymmetrical recording field. The recording interference between the fields at each side of the gap which deteriorates the output when a normal ring head with symmetrical head field is used to record on Co-Cr media, is no longer observed. As a consequence of the asymmetrical head field, the recorded magnetization is more perpendicular and the low-frequency output is higher.<>
