The linear density capability of thin-film media with a coercivity of about 2900 Oe and M/sub r/t ranging from 0.33 to 0.5 memu/cm/sup 2/ was studied with the advanced dual-spin valve heads used for the 14 Gbits/in/sup 2/ areal density demonstration. With a track error rate of 10/sup -7/ as the criterion, a linear density as high as 546 KFCI was achieved with the optimum head/medium design. Track edge noise was studied. Its effect on linear density design was examined, These results were used for designing the 14 Gbits/in/sup 2/ system.
