Abstract :
The objective of the present paper is to explore the capability and challenges of CPP-GMR heads by fabricating narrow track heads using common materials such as CoFe, NiFe, and Cu etc. currently used for CIP-GMR heads and by investigating bias current effect etc. on DET and QST performance at small sensor size.
