Abstract :
Summar form only given. We have successfully demonstrated magnetic recording at an areal density of 3 Gb/in2 with narrow track inductive-write MR-read dud element heads on low noise CO alloy thin fiim disks. In this demonstration, the write head is a ten turn thin film inductive head with thick (-3 pm) and narrow (-1.4 pm) P2 pole-tips. The read head consists of a 120A thick MR layer with soft-film biasing in the center read region for linearization and exchange-biasing at the tail regions for magnetic stabilization. head
