Abstract

PURPOSE:To hold the position of a magnetic head even when stopping the driving of the motor of the feeding mechanism of a magnetic head or the like by fixing the magnetic head etc., and correctly writing a servo pattern even with the application of a disturbance. CONSTITUTION:At the time of writing the servo pattern by a controller 10, or at the time of stopping or operating the motor according to the command of a host computer, the time and the fixed position of the magnetic head are decided to operate a brake 4 according to the command of the controller 10 and fix a carriage 2 and the magnetic head. Thereby, even when the disturbance is applied at the time of writing the servo pattern, the correct pattern can be written. According to the command of a host computer, when the magnetic disk stands by, the position can be held with a motor current cut. Further, a damage because of an impact or an oscillation in the operation at the time of charging no power of the magnetic disk can be prevented.
