Abstract :
Summary form only given. CIP-GMR (Current In-Plane GMR) film with 15-20% MR ratio could be applied to around 100 Gbpsi but it seems there are no major candidates for recording density over 100 Gbpsi. Now the most probable candidate i.e. the TMR (tunneling MR) head seems doubtful in terms of scalability toward the over 100 Gbpsi region because of its much higher resistance than CIP-GMR heads. We discuss the applicability of CPP-GMR (Current Perpendicular to Plane GMR), which is another candidate, for over 100 Gbpsi with simulation results and some experiment results.
