Abstract
A novel single-pole head on a flying slider is presented as a high fre quency writing head. The main pole of the head is driven with three th in-film conductor layers to have a short magnetic circuit path. Thus, a low inductance of around 10 nH and a high writing sensitivity of les s than 0.03 AT(p-p) is obtained. The writing field distribution is sho wn to be the same as a regular single-pole head by computer simulation s. The recording performance of the head is examined and the high writ ing sensitivity is demonstrated.
