摘要：

Using a merged MR head with novel CoB/Pt multilayers, various magnetic and recording properties were measured and compared with a commercial longitudinal media disk. At high frequency, about 3 dB of integrated SNR improvement was found compared with the longitudinal disk; Recording non-linearities, such as non-linear transition shift and partial erasure were also found to be smaller. Using various PRML channels, error rates below 1x10(-7) was achieved at low linear densities. The error I ate began to degrade at 300 kfci. Using an EPR4 channel, a raw error rate of 4x10(-4) was obtained at 350 kbpi with a data rate of 60 Mbits/sec.
