Abstract :
An accurate head positioning system uses a magnetoresistive head to generate a servo signal from radially magnetised servo patterns on a rigid disk. The servo patterns are written by a thin film transverse write head and occupies about 6.8% of data area for submicron track servo. Track following on 0.7 μm tracks has been demonstrated using the new servo method on longitudinal rigid disks
