摘要:
Data is written to a magnetic media, by applying a magnetic write field to the magnetic media with a write pole, in conjunction with a high frequency magnetic field, to the magnetic media to assist writing to the magnetic media. The high frequency magnetic field is generated by applying a specific write current waveform to the magnetic writer, resulting in the generation of a high frequency magnetic write field.
摘要:
A magnetoresistive (MR) sensor having a decreased electrical profile due to a confining of the device sense current within a conductive nanoconstriction. The MR sensor includes a giant magnetoresistive (GMR) stack and a layer of high resistivity material within the GMR stack. The layer of high resistivity material includes a nanoconstriction precursor. When a punch current is applied at the nanoconstriction precursor, a conductive nanoconstriction is formed through the layer of high resistivity material at the nanoconstriction precursor.
