MAGNETIC HEAD DRIVING UNIT |
摘要 |
A magnetic head driving unit according to the present invention includes a microprocessor. The microprocessor determines whether a first seek operation for positioning the head on an initial position of a cylinder is completed. If the first seek is not completed, analog switch is triggered ON by a control signal from the microprocessor. Upon the ON operation of the analog switch, the limiter restrains a driving current for a motor in a predetermined value, thereby preventing overrun of the motor. |
