Abstract

The magnetic recording characteristics of a giant magnetoresistive spin-valve head in combination with a perpendicular disk medium have been measured. The disk medium contains a 30-nm-thick Pt/CoCrTa multilayer displaying low noise and high remanence. A pulse width of 172 nm, a signal to noise ratio of 31 dB, and a rolloff D50 point of 120 kFCI were achieved. The parametric data and window margin testing show this recording system can support recording storage density of 3.5 Gbits/in2 using a simple peak detect channel at a data rate of 65 Mbits/s.
