PROBLEM TO BE SOLVED: To solve the problem that writing servo data takes much time when there is a write error. SOLUTION: A servo data writing device 21 is provided with: a push pin arm 31 which is interlocked with a magnetic head 25; a head position detection controller 32 which detects the position of the magnetic head 25 in cooperation with the push pin arm 31 and controls the position of the magnetic head 25; a writing controller 33 connected to the head position detection controller 32; and a writing section 34 which is connected with the writing controller 33 and writes servo data 20 in a magnetic disk 22 through the magnetic head 25. The position detection controller 32 detects the vibration amount of the magnetic head 25 and causes the writing controller 33 to perform repair processing to the servo data 20 written in the magnetic disk 22 through the magnetic head 25 based on the vibration amount. Thereby the intended object can be attained. COPYRIGHT: (C)2009,JPO&INPIT
