Abstract: PROBLEM TO BE SOLVED: To provide a read/write head which writes information to a magnetic medium and reads the information from the magnetic medium. SOLUTION: The read/write head 10 includes a write head which writes the information on the magnetic medium, a read head which reads the information from the magnetic medium and an electric circuit element 54 which is disposed adjacent to the read head and acts to generate an electromagnetic field of a direction approximately opposite to the direction of the electromagnetic field generated by the write head in the read head. A method for manipulating the read/write head 10 of a hard disk drive includes a step of writing data onto a hard disk and simultaneously a step of generating the electromagnetic field of the direction opposite to the electromagnetic field generated by the write head in the writing head.
