摘要：

Unshielded spin-valve sensors, exchange biased with TbCo (trackwidths from 2 to 80 mu m) and with NiO (2 mu m trackwidth) have been fabricated, showing a well-linearized and Barkhausen noise fi ee behaviour. The response at low. frequency of these TbCo biased sensors and the performance Of a TbCo biased head, implemented into a tape drive, is described. The results of shielded TbCo exchange biased sensors are discussed.
