Summary :

In the case of rigid disk files, improvements in the recording medium and the head are required to increase bit density. This letter reports a high recording density of 2600 bit/mm (65000 bit/i), achieved by using high coercive force (100 Oe) sputtered γ-Fe2O3 thin film media and a narrow gap (2g0.15µm)head.
