Write head for high anisotropy media |
摘要 |
A write head for writing information bits to magnetic storage media comprises a first write pole for producing a first magnetic field in a first direction and a second write pole for producing a second magnetic field such that the combined field from the two poles lies either substantially along the first direction or in a second direction that is substantially orthogonal to the first direction. The second write pole includes a free layer having magnetization controlled by spin transfer torque, and a first spacer positioned between the free layer and the first write pole. The write head can further include a pinned layer and a second spacer positioned between the pinned layer and the free layer. A disc drive that includes the write head and a method of writing to magnetic storage media that utilizes the write head are also included.
