Abstract
We have successfully demonstrated recording at areal densities as high as 3 6 Gb/in(2) at data rates as high as 173 Mbits/s (21.6 MB/s) and at a Bit-As pect-Ratio (BAR) of 7.3, using merged inductive-write/spin-valve-read heads on low noise thin film disks. Recording at a data rate of 590 Mbits/s (73. 8 MB/s) has also been achieved at the corresponding linear density of 231 K BPI, Comparisons with previous areal density demonstrations have also been summarized.
