A V-MR head with a track width of 2.5μm was reported. The structure of the head was applied to MR inductive heads with an areal density of 500-600 Mbits/in2 and there is reason to believe that the structure can be used to achieve an areal density of over 1 Gbits/in2. The structure also has the potential of high TPI and the grounded front gap has the potential of high BPI in near-contact recording.
