A magnetic recording head is described which is suitable for vertical magnetic recording on flexible magnetic media, and this head has a read/write pole flanked on each side by erase poles fixed at an extreme angle to the read/write pole. Fig. 1 shows a top view of one embodiment of the magnetic head 1 which comprises a read/write pole 2 and erase poles 3 slanted at an extreme angle to the track direction. All poles are energized by the same coil (not shown). The distance between transitions written by a slanted pole is much lower than that for a standard pole. If the angle between the poles is 85Œ, the ratio of densities written is equal to 11.
