Abstract :
A novel single-pole head on a flying slider is presented as a high frequency writing head. The main pole of the head is driven with three thin-film conductor layers to have a short magnetic circuit path. Thus, a low inductance of around 10 nH and a high writing sensitivity of less than 0.03 ATpp is obtained. The writing field distribution is shown to be the same as a regular single-pole head by computer simulations. The recording performance of the head is examined and the high writing sensitivity is demonstrated
