Abstract

A new design for a high writing-sensitivity single-pole head is proposed. The head is driven with regular pancake structure dual coils, which sandwiches the main-pole. The outer parts of both coils are exposed to the air bearing surface. These coils can generate a cusp field with bifilar connection. A high recording sensitivity of this new head has been clarified by the fact that a small magneto-motive force of less than 0.1 AT0-P can saturate a medium with a high-coercivity of 3.5 kOe.
