Tunneling magnetoresistive heads beyond 150 Gb/in/sup 2

Tunneling magnetoresistive (TMR) readers capable of 150 Gb/in/sup 2/ of areal density magnetic recording for hard disk drive were demonstrated with bit-error-rate performance. The head design used is basically a bottom type stack of Ta/PtMn/CoFe/Ru/CoFe/oxide barrier/CoFe/NiFe/Ta cap with abutted ha...
