Abstract
A method of writing a tracking servo signal pattern for a magnetic disc device includes the steps of recording only a first burst signal and a second burst signal with a servo track writer for writing tracking servo signals, followed thereafter by reproducing the first burst signal and the second burst signal with a magnetic head equipped in the magnetic disc device, and recording a third burst signal and a fourth burst signal with the magnetic head of the magnetic disc device, while controlling a position of the magnetic head in such a manner that a ratio in level of both of the reproduced signals becomes equal to a predetermined proportion.
