  • 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 hard bias stabilization. The electrical reader width is about 4 /spl mu/'' to reach a very high track density and shield-to-shield spacing is about 700 /spl Aring/ for high linear density. On-track bit… CONTINUE READING
