Abstract
A row bar for forming magnetic heads includes a row of magnetic head forming portions each having a magnetic head and a cutting portion adjacent to the magnetic heads. A row of bonding pads and a first ELG pad are provided at the magnetic head, a second ELG pad is provided at the cutting portion, both of the first and the second ELG pads are adapted for contacting with a probe during lapping process, and a conductive structure that is higher than surfaces of the first and the second ELG pads is formed at peripheries of the first and the second ELG pads respectively. Due to the conductive structures, a probe used in lapping process will be prevented from shifting from the ELG pads to ensure a stable contact, thereby obtaining efficient and accurate resistance measurement.
