摘要：
A magnetic head drive of the present invention comprises a composite magnetic head structured by integrally combining a write head into a record head and a magnetic disk having a servo area where position information of the composite magnetic head is recorded and a data area where data is recorded, and the servo area includes a positioning data area having head positioning information, and the head has an erased area generated by recording an AC signal having a frequency higher than a burst pattern in an area other than the burst pattern including information of positioning the composite magnetic head of said positioning data area.
