Abstract:
A method for writing servo patterns on a disk in a hard disk drive assembly, said assembly comprisinga disk having at least one magnetic surface in which a reference pattern has been written, determining a reference track, an actuator having a shaft engaged with said disk to provide rotational motion to said disk, an actuator arm, and a micro-actuated read/write head on said actuator arm, comprising the steps of: using said read/write head to position said actuator arm at a first fixed position over said reference track; maintaining said actuator arm at said first fixed position while displacing said read/write head and using said displaced read/write head to write a second servo pattern, determining a second track displaced from said reference track; using said read/write head to position said actuator arm at a second fixed position over said second track; and maintaining said actuator arm at said second fixed position while displacing said read/write head and using said displaced read/write head to write a third servo pattern determining a third track displaced from said second track.
