Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and a device for detecting the terminal open circuit and grounding short circuit in an induction head writing driver.  <P>SOLUTION: The method for detecting the short-circuit state by at least one of a pair of writing head terminals of the writing driver is provided, and by the writing driver, a writing current giving a polarity to the induction head is produced in accordance with the direction of the writing current when made to flow into an induction head assembly which is connected to a pair of writing head terminals. The method includes a step for producing a 1st current proportional to at least a part of the writing current made to flow in the 1st direction to the 1st writing head terminal of the writing driver. A 2nd current is produced, which is proportional to at least a part of the writing current made to flow in the 2nd direction opposite to the 1st direction to the 2nd writing head terminal of the writing driver. When an average value of the 1st current is different from an average value of the 2nd current by the specified amount, the short- circuit state is detected by at least one of the 1st and 2nd writing head terminals.  <P>COPYRIGHT: (C)2003,JPO
